Product Description

Claw Vacuum Pump (RC180)

Product Description

With claw vacuum pumps, 2 claw-shaped rotors turn in opposite direction inside the housing. Due to the shape of these claw rotors, the air or gas is sucked in, compressed and discharged. The claw rotors do not come into contact either with each other nor with the cylinder in which they are rotating. Tight clearances between the claw rotors and the housing optimise the internal seal and guarantee a consistently high pumping speed. A synchronisation gearbox ensures exact synchronisation of the claw rotors.

Claw vacuum pumps are driven by a directly flange-mounted asynchronous motor, with an efficiency class IE2.  Claw vacuum pumps are ideally suited to use with frequency-controlled drives. Claw vacuum pumps are available in a wide range of sizes.

There are also variants for special applications such as dust and gas explosion protection, high steam contents, gas tightness and increased oxygen contents.

Can Vacuum Pumps Be Used for Chemical Distillation?

Yes, vacuum pumps are commonly used in chemical distillation processes. Here’s a detailed explanation:

Chemical distillation is a technique used to separate or purify components of a mixture based on their different boiling points. The process involves heating the mixture to evaporate the desired component and then condensing the vapor to collect the purified substance. Vacuum pumps play a crucial role in chemical distillation by creating a reduced pressure environment, which lowers the boiling points of the components and enables distillation at lower temperatures.

Here are some key aspects of using vacuum pumps in chemical distillation:

1. Reduced Pressure: By creating a vacuum or low-pressure environment in the distillation apparatus, vacuum pumps lower the pressure inside the system. This reduction in pressure lowers the boiling points of the components, allowing distillation to occur at temperatures lower than their normal boiling points. This is particularly useful for heat-sensitive or high-boiling-point compounds that would decompose or become thermally degraded at higher temperatures.

2. Increased Boiling Point Separation: Vacuum distillation increases the separation between the boiling points of the components, making it easier to achieve a higher degree of purification. In regular atmospheric distillation, the boiling points of some components may overlap, leading to less effective separation. By operating under vacuum, the boiling points of the components are further apart, improving the selectivity and efficiency of the distillation process.

3. Energy Efficiency: Vacuum distillation can be more energy-efficient compared to distillation under atmospheric conditions. The reduced pressure lowers the required temperature for distillation, resulting in reduced energy consumption and lower operating costs. This is particularly advantageous when dealing with large-scale distillation processes or when distilling heat-sensitive compounds that require careful temperature control.

4. Types of Vacuum Pumps: Different types of vacuum pumps can be used in chemical distillation depending on the specific requirements of the process. Some commonly used vacuum pump types include:

– Rotary Vane Pumps: Rotary vane pumps are widely used in chemical distillation due to their ability to achieve moderate vacuum levels and handle various gases. They work by using rotating vanes to create chambers that expand and contract, enabling the pumping of gas or vapor.

– Diaphragm Pumps: Diaphragm pumps are suitable for smaller-scale distillation processes. They use a flexible diaphragm that moves up and down to create a vacuum and compress the gas or vapor. Diaphragm pumps are often oil-free, making them suitable for applications where avoiding oil contamination is essential.

– Liquid Ring Pumps: Liquid ring pumps can handle more demanding distillation processes and corrosive gases. They rely on a rotating liquid ring to create a seal and compress the gas or vapor. Liquid ring pumps are commonly used in chemical and petrochemical industries.

– Dry Screw Pumps: Dry screw pumps are suitable for high-vacuum distillation processes. They use intermeshing screws to compress and transport gas or vapor. Dry screw pumps are known for their high pumping speeds, low noise levels, and oil-free operation.

Overall, vacuum pumps are integral to chemical distillation processes as they create the necessary reduced pressure environment that enables distillation at lower temperatures. By using vacuum pumps, it is possible to achieve better separation, improve energy efficiency, and handle heat-sensitive compounds effectively. The choice of vacuum pump depends on factors such as the required vacuum level, the scale of the distillation process, and the nature of the compounds being distilled.

What Is a Vacuum Pump, and How Does It Work?

A vacuum pump is a mechanical device used to create and maintain a vacuum or low-pressure environment within a closed system. Here’s a detailed explanation:

A vacuum pump operates on the principle of removing gas molecules from a sealed chamber, reducing the pressure inside the chamber to create a vacuum. The pump accomplishes this through various mechanisms and techniques, depending on the specific type of vacuum pump. Here are the basic steps involved in the operation of a vacuum pump:

1. Sealed Chamber:

The vacuum pump is connected to a sealed chamber or system from which air or gas molecules need to be evacuated. The chamber can be a container, a pipeline, or any other enclosed space.

2. Inlet and Outlet:

The vacuum pump has an inlet and an outlet. The inlet is connected to the sealed chamber, while the outlet may be vented to the atmosphere or connected to a collection system to capture or release the evacuated gas.

3. Mechanical Action:

The vacuum pump creates a mechanical action that removes gas molecules from the chamber. Different types of vacuum pumps use various mechanisms for this purpose:

– Positive Displacement Pumps: These pumps physically trap gas molecules and remove them from the chamber. Examples include rotary vane pumps, piston pumps, and diaphragm pumps.

– Momentum Transfer Pumps: These pumps use high-speed jets or rotating blades to transfer momentum to gas molecules, pushing them out of the chamber. Examples include turbomolecular pumps and diffusion pumps.

– Entrapment Pumps: These pumps capture gas molecules by adsorbing or condensing them on surfaces or in materials within the pump. Cryogenic pumps and ion pumps are examples of entrainment pumps.

4. Gas Evacuation:

As the vacuum pump operates, it creates a pressure differential between the chamber and the pump. This pressure differential causes gas molecules to move from the chamber to the pump’s inlet.

5. Exhaust or Collection:

Once the gas molecules are removed from the chamber, they are either exhausted into the atmosphere or collected and processed further, depending on the specific application.

6. Pressure Control:

Vacuum pumps often incorporate pressure control mechanisms to maintain the desired level of vacuum within the chamber. These mechanisms can include valves, regulators, or feedback systems that adjust the pump’s operation to achieve the desired pressure range.

7. Monitoring and Safety:

Vacuum pump systems may include sensors, gauges, or indicators to monitor the pressure levels, temperature, or other parameters. Safety features such as pressure relief valves or interlocks may also be included to protect the system and operators from overpressure or other hazardous conditions.

It’s important to note that different types of vacuum pumps have varying levels of vacuum they can achieve and are suitable for different pressure ranges and applications. The choice of vacuum pump depends on factors such as the required vacuum level, gas composition, pumping speed, and the specific application’s requirements.

In summary, a vacuum pump is a device that removes gas molecules from a sealed chamber, creating a vacuum or low-pressure environment. The pump accomplishes this through mechanical actions, such as positive displacement, momentum transfer, or entrapment. By creating a pressure differential, the pump evacuates gas from the chamber, and the gas is either exhausted or collected. Vacuum pumps play a crucial role in various industries, including manufacturing, research, and scientific applications.

Vacuum Pump

Types of vacuum pumps

A vacuum pump is a device that draws gas molecules from a sealed volume and maintains a partial vacuum. Its job is to create a vacuum in a volume, usually one of several. There are several types of vacuum pumps, such as root pumps, diaphragm pumps, rotary piston pumps, and self-priming centrifugal pumps.

The diaphragm pump is a dry positive displacement vacuum pump

Diaphragm pumps are a versatile type of vacuum pump. They can be installed in a variety of scenarios including container emptying, positive suction, and simultaneous fluid mixing. Their performance depends on the stiffness and durability of the diaphragm, which in turn depends on the material.
They have good performance when running in dry mode. Diaphragm pumps work very similarly to the human heart, which is why they are often used to create artificial hearts. In addition, the diaphragm pump is self-priming and has high efficiency. They are also capable of handling the most viscous liquids and are used in almost all industries.
However, this type of pump has several disadvantages. One of them is that they are difficult to restart after a power outage. Another disadvantage is that they can generate a lot of heat. Fortunately, this heat is carried away by airflow. However, this heat builds up in the multistage pump. If this happens, the diaphragm or motor may be damaged. Diaphragm pumps operating in two or more stages should be fitted with solenoid valves to maintain vacuum stability.
Diaphragm pumps are a good choice for drying processes where hygiene is important. These pumps have check valves and rubber or Teflon diaphragms. Diaphragm pumps are also ideal for high viscosity applications where shear sensitivity is important.

Roots pumps are dry method centrifugal pumps

Roots pumps use a vane rotor pump with two counter-rotating vanes that move in opposite directions to move the gas. They are often the first choice for high-throughput process applications. Depending on the size and number of blades, they can withstand up to 10 Torr.
Centrifugal pumps have several advantages, including the ability to handle corrosive fluids and high temperatures. However, when choosing a pump, it is essential to choose a reputable manufacturer. These companies will be able to advise you on the best pump design for your needs and provide excellent after-sales support. Roots pumps can be used in a wide range of industrial applications including chemical, food, and biotechnology.
The Roots pump is a dry centrifugal pump whose geometry enables it to achieve high compression ratios. The screw rotors are synchronized by a set of timing gears that allow gas to pass in both directions and create a compressed state in the chamber. The pre-compressed gas is discharged through a pressure connection and cooled with water. Some pumps are also able to accept additional cooling gas, but this should be done with caution.
The size of the impeller plays an important role in determining the pump head. The impeller diameter determines how high the pump can lift the liquid. Impeller speed also affects the head. Since the head is proportional to the specific gravity of the liquid, the available suction pressure will be proportional to the density of the liquid. The density of water is about 1.2 kg/m3, and the suction pressure of the centrifugal pump is not enough to lift the water.

The rotary vane pump is a self-priming centrifugal pump

A rotary vane pump is a centrifugal pump with a circular pump head and a cycloid cam that supports the rotor. The rotor is close to the cam wall, and two side plates seal the rotor. Vanes in vane pumps are installed in these cavities, and the rotor rotates at high speed, pushing fluid in and out of the pump. The pump offers several advantages, including a reversible design and the ability to handle a wide variety of clean fluids.
Agknx Pumps manufactures a wide range of vane pumps that combine high performance, low cost, and easy maintenance. These pumps handle medium to high viscosity liquids up to 500 degrees Fahrenheit and 200,000 SSU.
The suction side of the rotary vane pump has a discharge port, and the valve prevents the backflow of the discharge air. When the maximum pressure is reached, the outlet valve closes to prevent the backflow of exhaust gas. The mechanical separation step separates the oil from the gas in the pump circuit and returns the remaining oil particles to the sump. The float valve then reintroduces these oil particles into the oil circuit of the pump. The gas produced is almost oil-free and can be blown out of a pipe or hose.
Rotary vane pumps are self-priming positive displacement pumps commonly used in hydraulic, aeration, and vacuum systems. Unlike gear pumps, rotary vane pumps can maintain high-pressure levels while using relatively low suction pressures. The pump is also very effective when pumping viscous or high-viscosity liquids.
Vacuum Pump

Rotary piston pumps are dry method positive displacement pumps

Rotary piston pumps are dry positive displacement pumps designed to deliver high-viscosity fluids. They are capable of pumping a variety of liquids and can run dry without damaging the liquid. Rotary piston pumps are available in a variety of designs. Some are single shafts, some are two shafts and four bearings.
Positive displacement pumps operate slower than centrifugal pumps. This feature makes the positive displacement pump more sensitive to wear. Piston and plunger reciprocating pumps are particularly prone to wear. For more demanding applications, progressive cavity, diaphragm or lobe pumps may be a better choice.
Positive displacement pumps are typically used to pump high-viscosity fluids. This is because the pump relies on a mechanical seal between the rotating elements and the pump casing. As a result, when fluids have low viscosity, their performance is limited. Additionally, low viscosity fluids can cause valve slippage.
These pumps have a piston/plunger arrangement using stainless steel rotors. Piston/piston pumps have two cavities on the suction side. The fluid then flows from one chamber to the other through a helical motion. This results in very low shear and pulsation rates. The pump is usually installed in a cylindrical housing.

Rotary vane pump corrosion resistance

Rotary vane vacuum pumps are designed for use in a variety of industries. They feature plasma-treated corrosion-resistant parts and anti-suck-back valves to help reduce the number of corrosive vapors entering the pump. These pumps are commonly used in freeze dryers, vacuum ovens, and degassing processes. The high flow rates they provide in their working vacuum allow them to speed up processes and reduce the time it takes to run them. Plus, they have energy-efficient motors and silent volume. <br/While rotary vane vacuum pumps are relatively corrosion resistant, they should not be used for aggressive chemicals. For these chemicals, the most suitable pump is the chemical mixing pump, which combines two types of pumps to improve corrosion resistance. If the application requires a more powerful pump, a progressive cavity pump (eg VACUU*PURE 10C) is suitable.
Oil seals used in rotary vane pumps are important to pump performance. The oil seal prevents corrosion of the aluminum parts of the rotary vane pump and prolongs the service life. Most rotary vane vacuum pumps have a standard set of components, although each component may have different oil seals.
Rotary vane vacuum pumps are the most common type of positive displacement pump. They provide quiet operation and long service life. They are also reliable and inexpensive and can be used in a variety of applications.
Vacuum Pump

Roots pumps are primarily used as a vacuum booster

Root vacuum pumps are mainly used as vacuum boosters in industrial applications. They need a thorough understanding of operating principles and proper maintenance to function properly. This course is an introduction to Roots vacuum pumps, covering topics such as pump principles, multi-stage pumps, temperature effects, gas cooling, and maintenance.
Roots pumps have many advantages, including compact and quiet operation. They do not generate particles and have a long service life. They also don’t require oil and have a small footprint. However, Roots pumps have several disadvantages, including relatively high maintenance costs and low pumping speeds near atmospheric pressure.
Root vacuum pumps are often used with rotary vane vacuum pumps. They work on the same principle, the air enters a conveying unit formed by two rolling pistons in the housing. The piston heads are separated from each other, and the air passes through the unit without being reduced until it is discharged. When the air in the next unit reaches a higher absolute pressure, it is expelled from the last unit.
Roots pumps can be classified as sheathed or sealed. Roots pumps with sealed motors are suitable for pumping toxic gases. They have less clearance between the stator and motor rotor and have a sealed tank.

What Is the Role of Vacuum Pumps in Pharmaceutical Manufacturing?

Vacuum pumps play a crucial role in various aspects of pharmaceutical manufacturing. Here’s a detailed explanation:

Vacuum pumps are extensively used in pharmaceutical manufacturing processes to support a range of critical operations. Some of the key roles of vacuum pumps in pharmaceutical manufacturing include:

1. Drying and Evaporation: Vacuum pumps are employed in drying and evaporation processes within the pharmaceutical industry. They facilitate the removal of moisture or solvents from pharmaceutical products or intermediates. Vacuum drying chambers or evaporators utilize vacuum pumps to create low-pressure conditions, which lower the boiling points of liquids, allowing them to evaporate at lower temperatures. By applying vacuum, moisture or solvents can be efficiently removed from substances such as active pharmaceutical ingredients (APIs), granules, powders, or coatings, ensuring the desired product quality and stability.

2. Filtration and Filtrate Recovery: Vacuum pumps are used in filtration processes for the separation of solid-liquid mixtures. Vacuum filtration systems typically employ a filter medium, such as filter paper or membranes, to retain solids while allowing the liquid portion to pass through. By applying vacuum to the filtration apparatus, the liquid is drawn through the filter medium, leaving behind the solids. Vacuum pumps facilitate efficient filtration, speeding up the process and improving product quality. Additionally, vacuum pumps can aid in filtrate recovery by collecting and transferring the filtrate for further processing or reuse.

3. Distillation and Purification: Vacuum pumps are essential in distillation and purification processes within the pharmaceutical industry. Distillation involves the separation of liquid mixtures based on their different boiling points.

This helps to prevent defects and imperfections caused by trapped air or bubbles in the final printed part.

5. Enclosure Pressure Control: Some 3D printing processes, such as selective laser sintering (SLS) or binder jetting, require the printing chamber to be maintained at a specific pressure or controlled atmosphere. Vacuum pumps are used to create a controlled low-pressure or vacuum environment within the printing chamber, enabling precise pressure regulation and maintaining the desired conditions for optimal printing results. This control over the printing environment helps to prevent oxidation, improve material flow, and enhance the quality and consistency of printed parts.

6. Post-Processing and Cleaning: Vacuum pumps can also aid in post-processing steps and cleaning of 3D printed parts. For instance, in processes like support material removal or surface finishing, vacuum systems can assist in the removal of residual support structures or excess powder from printed objects. They can also be employed in vacuum-based cleaning methods, such as vapor smoothing, to achieve smoother surface finishes and enhance the aesthetics of the printed parts.

7. System Maintenance and Filtration: Vacuum pumps used in 3D printing systems require regular maintenance and proper filtration to ensure their efficient and reliable operation. Effective filtration systems within the vacuum pumps help to remove any contaminants or particles generated during printing, preventing their circulation and potential deposition on the printed parts. This helps to maintain the cleanliness of the printing environment and minimize the risk of defects or impurities in the final printed objects.

In summary, vacuum pumps have a significant impact on the quality of 3D printing. They contribute to material handling and filtration, build plate adhesion, material drying, resin handling in SLA, enclosure pressure control, post-processing and cleaning, as well as system maintenance and filtration. By utilizing vacuum pumps in these critical areas, 3D printing processes can achieve improved accuracy, dimensional stability, material quality, and overall print quality.

Can Vacuum Pumps Be Used in Food Processing?

Yes, vacuum pumps are widely used in food processing for various applications. Here’s a detailed explanation:

Vacuum pumps play a crucial role in the food processing industry by enabling the creation and maintenance of vacuum or low-pressure environments. They offer several benefits in terms of food preservation, packaging, and processing. Here are some common applications of vacuum pumps in food processing:

1. Vacuum Packaging: Vacuum pumps are extensively used in vacuum packaging processes. Vacuum packaging involves removing air from the packaging container to create a vacuum-sealed environment. This process helps extend the shelf life of food products by inhibiting the growth of spoilage-causing microorganisms and reducing oxidation. Vacuum pumps are used to evacuate the air from the packaging, ensuring a tight seal and maintaining the quality and freshness of the food.

2. Freeze Drying: Vacuum pumps are essential in freeze drying or lyophilization processes used in food processing. Freeze drying involves removing moisture from food products while they are frozen, preserving their texture, flavor, and nutritional content. Vacuum pumps create a low-pressure environment that allows frozen water to directly sublimate from solid to vapor, resulting in the removal of moisture from the food without causing damage or loss of quality.

3. Vacuum Cooling: Vacuum pumps are utilized in vacuum cooling processes for rapid and efficient cooling of food products. Vacuum cooling involves placing the food in a vacuum chamber and reducing the pressure. This lowers the boiling point of water, facilitating the rapid evaporation of moisture and heat from the food, thereby cooling it quickly. Vacuum cooling helps maintain the freshness, texture, and quality of delicate food items such as fruits, vegetables, and bakery products.

4. Vacuum Concentration: Vacuum pumps are employed in vacuum concentration processes in the food industry. Vacuum concentration involves removing excess moisture from liquid food products to increase their solids content. By creating a vacuum, the boiling point of the liquid is reduced, allowing for gentle evaporation of water while preserving the desired flavors, nutrients, and viscosity of the product. Vacuum concentration is commonly used in the production of juices, sauces, and concentrates.

5. Vacuum Mixing and Deaeration: Vacuum pumps are used in mixing and deaeration processes in food processing. In the production of certain food products such as chocolates, confectioneries, and sauces, vacuum mixing is employed to remove air bubbles, achieve homogeneity, and improve product texture. Vacuum pumps aid in the removal of entrapped air and gases, resulting in smooth and uniform food products.

6. Vacuum Filtration: Vacuum pumps are utilized in food processing for vacuum filtration applications. Vacuum filtration involves separating solids from liquids or gases using a filter medium. Vacuum pumps create suction that draws the liquid or gas through the filter, leaving behind the solid particles. Vacuum filtration is commonly used in processes such as clarifying liquids, removing impurities, and separating solids from liquids in the production of beverages, oils, and dairy products.

7. Marinating and Brining: Vacuum pumps are employed in marinating and brining processes in the food industry. By applying a vacuum to the marinating or brining container, the pressure is reduced, allowing the marinade or brine to penetrate the food more efficiently. Vacuum marinating and brining help enhance flavor absorption, reduce marinating time, and improve the overall taste and texture of the food.

8. Controlled Atmosphere Packaging: Vacuum pumps are used in controlled atmosphere packaging (CAP) systems in the food industry. CAP involves modifying the gas composition within food packaging to extend the shelf life and maintain the quality of perishable products. Vacuum pumps aid in the removal of oxygen or other unwanted gases from the package, allowing the introduction of a desired gas mixture that preserves the food’s freshness and inhibits microbial growth.

These are just a few examples of how vacuum pumps are used in food processing. The ability to create and control vacuum or low-pressure environments is a valuable asset in preserving food quality, enhancing shelf life, and facilitating various processing techniques in the food industry.

How to install a vacuum pump

A vacuum pump creates a relative vacuum within a sealed volume by drawing gas molecules from the sealed volume. Vacuum pumps can be used in a variety of industrial applications. They also offer various lubrication options. If you are considering purchasing, please understand its functions and features before purchasing.

How it works

The working principle of a vacuum pump is called gas transfer. The principle can be further divided into two basic categories: positive displacement and momentum transfer. At high pressure and moderate vacuum, gas molecules collide and move and create a viscous flow. At higher vacuum levels, gas molecules separate to create molecular or transitional flows.
Another principle of vacuum pumps is fluid-tightness. There are two main types of seals: rotary seals and screw seals. Rotary seals prevent liquid leakage, while screw seals only allow liquids to flow out at higher pressures. Some pumps may not use the third seal.
The flow rate of the vacuum pump determines the machine’s ability to pump a certain amount of material. A higher pumping speed will shorten the drain time. Therefore, the mass flow of the vacuum pump must be carefully considered. The speed and type of vacuum must also be considered.
The working principle of a vacuum pump is to push gas molecules from a high-pressure state to a low-pressure state. This creates a partial vacuum. There are many different types of vacuum pumps, each with different functions. Some are mechanical, some are chemical. In either case, their function is the same: to create a partial or complete vacuum. Vacuum pumps use a variety of technologies and are sized according to the application. Proper sizing is critical for optimum efficiency.
Gas transfer pumps use the same principles as vacuum pumps but use different technology. One of the earliest examples is the Archimedes spiral. Its structure consists of a single screw inside a hollow cylinder. More modern designs use double or triple screws. The rotation of the screw causes gas molecules to be trapped in the cavity between the screw and the housing. The fluid is then discharged at slightly above atmospheric pressure. This difference is called the compression ratio.
Another type of vacuum pump is a diffusion pump. Its main use is industrial vacuum processing. It is used in applications such as mass spectrometry, nanotechnology and analytical instrumentation. These pumps are generally inexpensive to purchase and operate.


Vacuum pumps are essential for many scientific and industrial processes. They are used in the production of vacuum tubes, CRTs, lamps and semiconductor processing. They can also be used to support mechanical equipment. For example, they can be mounted on the engine of a motor vehicle. Likewise, they can be used to power hydraulic components of aircraft. Among other uses, the vacuum pump helps calibrate the gyroscope.
Vacuum pumps are widely used in the pharmaceutical industry and are one of the largest users of this technology. They help deal with hazardous materials and eliminate waste quickly. They are also used in power jets, dump fuel tanks and rear doors, among others. However, they are sensitive to contamination and should only be used in environments where leaks can be prevented. Therefore, choosing the right fluid for the application is very important.
The most popular type of vacuum pump is the rotary vane pump. These pumps are known for their high pumping speed and low pressure. Their efficient pumping capacity allows them to reach pressures below 10-6 bar. Additionally, they are usually oil-sealed and have excellent vacuuming capabilities.
Vacuum pumps are often used to remove air from closed systems. They create a vacuum by reducing the density of the air in the compressed space. This is done by using the mechanical force energy generated by the rotating shaft. When the pump is under pressure, it converts this energy into pneumatic power. When the pressure is different, the energy produced depends on the volume of the gas and the pressure difference between the inner and outer atmospheres.
Vacuum pumps are also used in the manufacture of solar cells. They are used in the manufacture of solar cells, including ingot casting processes as well as cell and module processes. The design of the vacuum system plays an important role in reducing the cost of the process, thus making it profitable. Due to their low maintenance costs, they are an invaluable tool for making solar cells.
Vacuum pumps are widely used in many applications. In addition to industrial and research uses, they are also used in water remediation.
Vacuum Pump

Oil Lubrication Option

Vacuum pumps are available in a variety of oil lubrication options. Choosing the right lubricant can help protect your vacuum pump and maximize its performance. Different base oils may contain different additives, such as antioxidants, and some contain additional additives for specific purposes. You should choose an oil with the right concentration of these additives for optimal lubrication of your vacuum pump.
Vacuum pumps are usually lubricated with paraffinic mineral oil. However, this type of lubricant evaporates as the temperature increases. To minimize evaporative losses, choose a lubricant with low vapor pressure. Also, you should choose lubricants that are resistant to extreme temperatures. Extreme temperatures can put extra stress on the oil and can even significantly shorten the life of the oil.
In terms of viscosity, synthetic oils are the best choice for vacuum pumps. These types of oils are designed to resist gas dissolution and are more resistant to corrosion. Therefore, synthetic oils are ideal for handling aggressive substances. Whether or not your pump needs lubrication, choosing a quality product is important.
The vacuum pump oil should be changed periodically according to the manufacturer’s recommendations. If you use a filter, you should also change the oil as soon as the filter reaches the end of its life. Unplanned oil changes will eventually cause the vacuum pump to not reach its maximum vacuum capacity.
You can buy vacuum pump oil from vacuum pump manufacturers or other suppliers. These options are available in a variety of sizes, and labels can be customized. The oil should be designed for the pump. However, you should check the manufacturer’s recommendations to avoid buying the wrong type.
If you choose to use a synthetic oil, it is important to use a good quality oil. It helps the pump work more efficiently and prolong its life.
Vacuum Pump


After choosing a suitable location, the next step is to install the pump. First, place the pump on a flat surface. Then, screw the pump onto the motor body above the check valve. Make sure the accessories are wrapped with sealing tape and secured with screws. The direction of gas inflow and outflow is indicated by arrows on the pump. The direction of rotation around the pump is also shown.
During commissioning, check the operation of each part of the pump. If the pump is equipped with a pipe connection, the pipe should be the same size and shape as the pump flange. Also, make sure that the piping does not cause any pressure drop. In addition, the first three weeks of operation require the installation of protective nets at the suction ports.
When selecting a pump, consider the back pressure of the system. Too much back pressure will affect the capacity of the vacuum pump. Also, check the temperature of the seal. If the temperature is too high, the seal may be damaged. It could also be due to a partially closed valve in the recirculation line or a clogged filter. Circulation pumps and heat exchangers should also be checked for fouling.
The vacuum pump is usually installed in the chassis area of ​​the car. They can be mounted next to the engine or on a lower support frame. They are usually fastened to the bracket using suitable shock absorbers and isolating elements. However, before installing the vacuum pump, be sure to check the vacuum pump’s wiring harness before connecting it to the vehicle.
In many experimental setups, a vacuum pump is essential. However, improperly installed vacuum pumps can expose users to harmful vapors and chemicals. Appropriate plugs and belt guards should be installed to prevent any accidental chemical exposure. It is also important to install a fume hood for the pump.
In most cases, vacuum pumps come with installation manuals and instructions. Some manufacturers even offer start-up assistance if needed.
