™ Test Procedure to Evaluate Fluids in Open Loop Axial Piston Pumps Technical Data V-PUPI-TS022-E Pump Model PVH57C-RF-2S-11-C25V-31 This test procedure is to evaluate fluids for use in open loop axial piston pumps. It consists of 250 hours of actual test time (not including break-in or performance running). The operation temperature is dependent upon the capability of the test fluid as specified by the fluid manufacturer or the rated temperature specified for the pump, whichever is lower. Inlet fluid temperature must be maintained per fluid/pump rating throughout the complete test.

Record the results on the Test Fluid Record (page 13). • Viscosity cSt @ 40°C • Water content wt % (0.03% max. non-water based fluid) • Cleanliness level ISO Code 18/16/14 or better • Spectrographic analysis for at least the following elements (ppm): P, Zn, Ca, K, Ba, B, Si, Fe, Cu, Pb, Sn • Total Acid Number (TAN) mg/KOH (Report only for vegetable and synthetic environmentally acceptable hydraulic fluids, and polyolester fire resistant hydraulic fluids.) Fluid Pass/Fail Criteria The following are the criteria by which the fluid is judged to have passed or failed the test: more than 5% at the end of the 200-hour cyclic test. • The overall efficiency of the pump is equal to or greater than 85%. • The control pressure hysteresis is less than or equal to 45 bar (652.5 psi) at the end of the 200-hour cyclic test. • The volumetric efficiency of the pump is not degraded by EATON CORPORATION Fluid Power Test Procedure to Evaluate Fluids in Piston Pumps Technical Data V-PUPI-TS022-E March 2009 7 Glossary Pressure Compensator Cut-off: The pump is at maximum pressure without any outlet flow. The control has de-stroked the pump giving it the minimum displacement to maintain the outlet pressure. Load Sense Stand-by: The pump is at minimum pressure without any outlet flow. The control has de-stroked the pump giving it the minimum displacement to maintain the de-stroked position. The load sense signal line is at zero pressure. Valve Plate: Cradle (saddle) Bearings: The plate between the cylinder barrel and end cover on which the cylinder barrel surface runs. The surface on which the swashplate rotates to determine the displacement. Cylinder Barrel (block): The body in which the pistons reciprocate producing flow. Swashplate (yoke): The surface on which the shoes of the piston/shoe assemblies run. The swashplate also determines the displacement of the pump. The control piston and bias piston provide the forces to position the swashplate.

Pump is now at cut-off (pressure compensation mode, high pressure, no flow). 2 Open variable orifice valve 22 to vary the pump outlet pressure to run a control pressure hysteresis check per Appendix B. 3 Once the control pressure hysteresis check has been completed, close the variable orifice valve 22 and resume test. Control Pressure Hysteresis Check Procedure Control pressure hysteresis is calculated using a plot of outlet flow versus control pressure. To check control pressure hysteresis, plot outlet flow (on the y-axis) versus control piston pressure while varying outlet pressure from 500 psi (at full flow) to the compensator setting (high-pressure, no-flow condition) and back to 500 psi (at full flow). An adapter block needs to be assembled between the control and the end cover (valve block) to pick up control piston pressure. Use a variable orifice valve to vary the pump’s outlet pressure (refer to page 3 for preparatory steps). It may take 1.5 to 2.0 minutes to run a sweep from full flow to pressure compensation and back again. The majority of the sweep time should be while the pump is going into and out of the compensator mode. After generating a plot of outlet flow vs. control piston pressure: • Determine the full flow value. • Draw horizontal lines on the plot at 75%, 50% and 25% of full flow. • Determine the pressure values at which these lines intersect the vertical sections of the plot. (Note: There will be two intersection points for each horizontal line.) • Calculate the difference between each pair of pressure values (one ∆p for 75% flow, one ∆p for 50% flow, and one ∆p for 25% flow). • Take the average of these three ∆p values. This is considered the average control pressure hysteresis. This value should not exceed 45 bar (652.5 psi). A sample curve is shown in Figure 8.
