5.2 High Pressure Flow Measurement
1.
Attach a V-152 relief valve to advance port of the valve on
the pump. Install a 0-15,000 psi pressure gauge onto the
extra V-152 port and a low restriction return hose to the
bottom (tank port) of the V-152.
2.
Connect the hose from the V-152 valve to the test bench
flow meter supply. Route the flow meter return hose back
to the return port of the pump valve (for 4 way valves) or the
reservoir (for 3 way valves).
3.
Fully open the V-152 valve (turning its handle counter-
clockwise).
4.
Plug the pump into an electrical power supply.
5.
Start the motor and operate the pump in the advance
mode.
6.
Monitor the system pressure and slowly close the V-152
valve by turning its handle clockwise until 85% of maximum
pressure is reached.
7.
Check Test Specification Table. If pump did not meet 2nd
stage flow ratings see Section 1.0 Troubleshooting.
8.
Stop the pump motor and unplug the pump from its
electrical power supply.
9.
Disconnect the flow meter hoses from the pump.
10. Remove the V-152 valve and pressure gauge and restore
the pump to its original condition.

5.3 Low Pressure Flow Measurement
1.
Verify sufficient oil exists inside the pump reservoir to
complete this test.
2.
Connect an unrestricted hose from the advance port of the
pump valve to a graduated cylinder or beaker (ensure the
container contains sufficient volume to complete the test –
also take care that the initial flow oil flow surge will not tip
it over or cause the hose to jump outside).
3.
Plug the pump into an electrical power supply.
4.
Start the motor and operate the pump in the advance
position for 30 seconds.
5.
Stop the pump motor and unplug the pump from its
electrical power supply.
6.
Calculate the flow rate by dividing the amount of oil
collected in the cylinder or beaker and dividing by 30
seconds (0.5 minutes).
7.
Check Test Specification Table. If pump does not meet 1st
stage flow rating see Section 1.0 Troubleshooting.
8.
Disconnect the hose from the pump and return the pump to
its original condition.
5.4 High Pressure Flow Measurement
1.
Verify sufficient oil exists inside the pump reservoir to
complete this test.
2.
Attach a V-152 relief valve to advance port of the valve on
the pump. Install a 0-15,000 psi pressure gauge onto the
extra V-152 port and a low restriction return hose to the
bottom (tank port) of the V-152.
3.
Route the hose from the V-152 valve to an oil sump
and prepare a graduated cylinder or beaker (ensure the
container contains sufficient volume to complete the test)
4.
Fully open the V-152 valve (turning its handle counter-
clockwise).
5.
Plug the pump into an electrical power supply.
6.
Start the motor and operate the pump in the advance
position.
7.
Monitor the system pressure and slowly close the V-152
valve by turning its handle clockwise until 85% of maximum
pressure is reached.
8.
Shift the return oil hose from the sump to the graduated
cylinder or beaker and continue running the pump in the
advance position for 30 seconds.
9.
Stop the pump motor and unplug the pump from its
electrical power supply.
10. Calculate the flow rate the dividing the amount of oil
collected in the cylinder or beaker and dividing by 30
seconds (0.5 minutes).
11. Check Test Specification Table. If pump does not meet 2nd
stage flow rating see Section 1.0 Troubleshooting.
12. Remove the V-152 valve, pressure gauge and hose and
restore the pump to its original condition.
