Dimension: 20, 21, 22, 23, 24, 25, 26, 27
Nominal strain 210 bars, Highest force 350 bars.
 
The Sauer PV axial piston variable displacement pumps, Sequence twenty, are of swash plate construction with variable stream capability suitable for hydrostatic transmissions with shut circuit. The circulation rate is proportional to the pumps driven speed displacement, which, in flip, is identified by the swash plate angle. The latter is infinitely adjustable among zero and greatest displacement. Movement route is reserved by titling the swash plate to the opposite facet of the neutral or zero displacement placement. These models and areas are in shape, form and operate replacements for Sauer-Sundstrand series twenty parts.
 
– Ideal for a variety of purposes
– A number of displacements and alternatives obtainable
– eight different body sizes
– Engineered to offer a extended services life and reliability
– Set displacement motor can be operated in both route of rotation
– Multiple push shaft possibilities and management alternatives
– Heavy responsibility bearings and shafts
– Effortlessly serviceable
– Alternative elements also offered
– Immediate replacements for Sauer-Sundstrand
 
Characteristics of CZPT Sauer PV pump
The total-length shaft with a high productive tapered roller bearing arrangement delivers a higher loading potential for exterior radial forces. Additional pumps can be constructed on. The hydro-mechanical servo displacement handle maintains the chosen swash plate position and that’s why pump displacement.
Upon launch of the management manage, the swash plate routinely returns to the null placement and the flow grow to be zero.
Large case pressures can be archived without leakage even at the least expensive temperature by using suitable shaft seals. The servo valve arrangement offers the facility to include function regulators and remote handle technique. Axial piston units are made for simple servicing, complete dismantling and reassembly can be carried out CZPT hand equipment, and all elements or sub-assemblies are replaceable.
Servo Displacement Handle (Linear response)
Standard by management handle on the servo valve, the swash plate can be infinitely varied in both instructions with the help of the servo program.
The pump displacement ensuing from any manage manage position can be proven employing figures.
The angle of the control handle for stroke initiation and for the ultimate position of the stroke can differ from unit to unit inside the assortment of the tolerance band.
