High Efficiency Hydraulic Piston Pump PVE

1.Variable axial piston pump in swash plate design for hydrostatic drives in open circuits Flow is proportional to drive speed and displacement.

2.The flow is infinitely variable by adjustment of the swash plate.
3.Strong bearings for long service life
4.High permissible drive speeds
5.High power to weight ratio
6.Small dimensions

Detailed Description

Eaton PVE piston pumps are inline, variable displacement pumps that are available in three displacement sizes. An assortment of optional controls offer maximum operating flexibility.

Pump displacement is varied by means of pressure and/or flow compensator controls.

Features and Benefits

1.Inline, variable displacementpump

2.Displacement is varied bypressure/flow compensatorcontrols

3.Optional controls formaximum operating flexibility

4.Thru-drive available on PVE19/21

Technical Data

Preparation for Start-up

Before starting a PVE pump, fill the case through the uppermost drain port with clean system hydraulic fluid. The case drain line must be connected to the reservoir below oil level. For multiple pump arrangements that include non-PVE sections, the requirements of the non-PVE units must also be considered.

Mounting

Eaton Hydraulics recommends these PVE series piston pumps be mounted horizontally.

PRESSURE LIMITS

Port	Pressure Range
Inlet^**	0,2 bar to 2,0 bar (5 in. Hg. vacuum to 30 psi)
Outlet	See Maximum Pressures listed above
Drain^*	0,35 bar (5 psig) maximum

*Integral relief valve protects pump by limiting case pressure peaks to 0,7 bar

(10 psi) above inlet pressure. Flow from valve returned directly to pump inlet.

Case drain line required to limit steady-state case pressure.
