Product Description

PV20 PV21 PV23 PV25 Hydraulic Axial Piston Pump

Product Description

The Sauer PV axial piston variable displacement pumps, Series 20, are of swash plate construction with variable flow capability suitable for hydrostatic transmissions with closed circuit. The flow rate is proportional to the pumps driven speed displacement, which, in turn, 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 opposite side of the neutral or zero displacement position. These units and parts are fit, form and function replacements for Sauer-Sundstrand series 20 components.

Eaton has the lead position in providing reliable and durable system solutions for transit mixers-vehicles on which downtime can mean disaster. Whether the truck is traveling down a highway or idling at a traffic light, the drum must maintain a consistent rotation speed. That's no problem when Eaton is on the inside. Eaton pump and motor provide the high pressure and high flow required to keep drums rotating.
 Advanced cylinder barrel design - permits high speed and pressure.
Fixed clearance slipper hold down - on Models 39 through 64 allows operation at high speed and reduces friction. Model 76 is a ball guide unit.
Pistons - have long engagement with cylinder bore resulting in low leakage.
Hydraulic servo control - provides low effort operation with low control pressure. Large servo pistons hold swash plate position and provide damping.
Large case drain ports - minimize case back pressure.
