Electric Test Pump Dixon 800.355.1991
Procedure for Hydrostatic Testing using Electric Test Pump (E.T.P.)
It is very important to know the parameters of the test being conducted. Follow the hose
manufacturer, recommendations of Rubber Manufacturers Association (R.M.A.), OSHA, or
other regulatory bodies guidelines for specific test parameters. The test should be carefully
monitored and all results recorded. Dixon recommends the following
sequence for a successful test:
1. Determine the test pressure of the assembly to be tested.
2. Make sure that the test caps or test plugs and all connections are tight on the test
sample.
3. Connect test specimen (hose) to high pressure outlet intermediate hose. Connection
between test specimen (hose) and intermediate hose should be tight.
4. Connect the bleed-off valve to the other end of the test sample.
5. Open the bleed-off valve on the test sample.
6. Open water inlet valve (1 - see drawing on page 6) to fill test specimen (hose)
7. Fill test sample with water. Vent all air from test sample by keeping the bleed-off valve
elevated until a solid stream of water (no bubbles) is coming out of the bleed-off valve.
8. Close the bleed-off valve at this point. Recommended bleed-off valve 3,000 psi minimum.
9. Turn pressure control knob (2 -see drawing on page 6). Pressure knob located at right hand
side of pump.
10. Start pump (3 - see drawing on page 6). Switch is located on the same side of the pump
as the pressue control knob.
Warning!
Do not turn off water supply once test sample has been filled with water
