FINAL PUMP TEST
Operate the pump with the following outlet pressures for the times indicated.
3000 psi ± 100 psi, 207 bar ± 6,9 bar 2 minutes minimum
5000 psi ± 100 psi, 345 bar ± 6,9 bar 1 minute minimum
6000 psi ± 100 psi, 414 bar ± 6,9 bar 1 minute minimum
While breaking in, destroke the pump several times at each pressure setting, by either reducing compensator setting,
servo/stroker command, or Q command to PQ control, as applicable.
FULL DISPLACEMENT REQUIREMENTS AT 6000 PSI, 414 BAR
PUMP SERIES MINIMUM OUTPUT FLOW MAX CASE DRAIN FLOW
GPM LPM GPM LPM
P07/P110 @ 1750 RPM 47.0 178 3.0 11,4
P07/P110 @ 1450 RPM 41.3 156 3.0 11,4
Raise compensator setting from minimum to maximum outlet pressure. Caution: Load sensing control is limited to 5000
psi, 345 bar maximum pressure.
At each condition, increase the outlet pressure until the pump fully de-strokes. At no time should the outlet pressure vary
over 150 psi, 10,3 bar from full to zero flow. The control should be steady and stable at all conditions.
Reduce outlet pressure to 150 psi, 10,3 bar below the compensator setting. Pump should return to full displacement.
Repeat two or more times. Compensator settings should be repeatable. Set compensator at 1000 psi ± 100 psi, 69 bar
± 6,9 bar standard, or desired value.
Check for leaks. NO external leaks are permitted. The shaft seal can be dry or damp. (Damp: A very small amount of
oil at the seal and shaft joint, but NOT running onto the seal face).
