Hydraulic Vane Pump – 20vq Vane Steering Pump; Hydraulic Gear Pump; Hydraulic Piston Pump

Hydraulic Vane Pump - 20vq Vane Steering Pump Hydraulic Gear Pump Hydraulic Piston Pump

The composite construction with hydraulically well balanced makes the pump have the qualities of large strain, big stream, modest quantity, stable procedure and lower sound. The pump is a plug-in construction, which can modify the movement package on web site and shorten the downtime. In addition, the series of vane pumps have complete requirements, outstanding overall performance and dependability, easy and sensible knots, and practical installation and upkeep.

Technical Attribute
01.The optimum design and style of the core even more lowers strain, stream pulsation and sound
02.Reliable strain stability compensation hole can attain greater volumetric effectiveness
03.Higher force, large movement rate and basic structure
04.The use of a better versatile aspect plate framework can routinely compensate the end experience clearance, enhance the speed of the oil pump, and properly improve the support life of the oil pump
05.The facet plate is made of bimetal substance, which enhances the anti occlusive efficiency and tends to make the pump existence lengthier
06.CZPT specifications, effortless installation and servicing
