I am translating a manual for Enerpac Track Lift Solution. In the manual, there are, "Install the pressure gauge onto the extra V-152 port and a low restriction return hose to the bottom (tank port) of the V-152." "Connect an unrestricted hose from the advance port of the pump valve to the test bench flow meter supply." what do "low restriction return hose" and "unrestricted hose" mean? can i think of it as an electrical wire that has low resistance/no resistance? Or do they mean soemthing else? Including excerpt is below However, the excerpt is... F FLOW TEST PROCEDURE FLOW METER METHOD (requires test bench) F.1 Low Pressure Flow Measurement 1. Connect an unrestricted hose from the advance port of the pump 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). 2. Plug the pump into an electrical power supply. 3. Start the motor and operate the pump in the advance mode for 30 seconds. 4. Check Test Specification Table. If pump does not meet 1st stage flow rating see Section 1.0 Troubleshooting. 5. Stop the pump motor and unplug the pump from its electrical power supply. 6. Disconnect the flow meter hoses from the pump and return the pump to its original condition. F.2 High Pressure Flow Measurement 1. Attach a V-152 relief valve to advance port of the valve on the pump. Install a 0-15000 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 f low 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).
enerpac couplers shut off when not connected "fully". Make sure your connectors are very much tight or they remain blocked. As far as return to pump, they might use a non shut off connector, also the valved connectors do add some resistance to the line.
Thanks for the reply, but what I am having trouble understanding is what "low restriction hose" and "unrestricted hose" are. Do they describe the type of hose? Can I think of "restrction" as resistance in electrical wire?
Is there an illustrated parts list showing the different hoses with "titles". If you could show illustrations of the two hoses someone might be able to make sense of it all.
unfortuntely, no illustration.. However, the excerpt is... F FLOW TEST PROCEDURE FLOW METER METHOD (requires test bench) F.1 Low Pressure Flow Measurement 1.

Do you have all the parts in that case.? If you do, can you take photos of the hoses.? Have you tried searching on YouTube.? Are you creating a manual for operating this system or for testing it.?
I'm guessing it's poorly worded for pressure ratings.
