Description  

Closed circuit
Series twenty
Size: twenty, 21, 22, 23, 24, 25, 26, 27
Nominal strain 210 bars, Highest strain 350 bars.
 
The Sauer PV axial piston variable displacement pumps, Sequence twenty, are of swash plate construction with variable circulation capacity suitable for hydrostatic transmissions with shut circuit. The circulation fee is proportional to the pumps pushed velocity displacement, which, in change, is determined by the swash plate angle. The latter is infinitely adjustable between zero and maximum displacement. Flow direction is reserved by titling the swash plate to the reverse side of the neutral or zero displacement situation. These units and areas are in shape, type and purpose replacements for Sauer-Sundstrand series twenty components.

– Substitution elements also offered
– Immediate replacements for Sauer-Sundstrand
 
Functions of CZPT Sauer PV pump
The full-size shaft with a high successful tapered roller bearing arrangement delivers a higher loading ability for exterior radial forces. Added pumps can be constructed on. The hydro-mechanical servo displacement manage maintains the chosen swash plate place and therefore pump displacement.
Upon release of the handle handle, the swash plate automatically returns to the null placement and the stream turn out to be zero.
High case pressures can be archived with no leakage even at the lowest temperature by using appropriate shaft seals. The servo valve arrangement offers the facility to integrate function regulators and distant manage technique. Axial piston models are created for effortless servicing, full dismantling and reassembly can be carried out CZPT hand instruments, and all parts or sub-assemblies are replaceable.
Servo Displacement Handle (Linear response)
Standard by control take care of on the servo valve, the swash plate can be infinitely diverse in each directions with the aid of the servo system.
The pump displacement resulting from any manage handle place can be set up using figures.
The angle of the handle take care of for stroke initiation and for the final position of the stroke can differ from unit to device within the range of the tolerance band.
