EATON CORPORATION Fluid Power

Test Procedure to Evaluate Fluids in Piston Pumps Technical Data V-PUPI-TS022-E March 2009

Installation

Fluid Ratings

For standard anti-wear
petroleum base fluids, the
PVH57 pump has the following
ratings:
• Rated Speed: 2400 rpm
• Rated Pressure: 250 bar (3625

psig)

• Rated Temperature: 95°C

(203°F)

• Inlet Pressure: Atmospheric

Pressure 1 bar absolute (0
psig)

For performance testing, the
PVH57 is to be tested at the
ratings listed in Table 1.

Install pump into test circuit per
Figure 1. Fill the pump case with
pre-filtered anti-wear petroleum-
based hydraulic fluid.
