4. The method used to prime the system will vary with the chosen barrier fluid. The fluid must
be introduced under pressure on the inlet side. This pressure can be normal water pressure if
water is being used. It can be provided by a pressurized tank and/or a hand pump. Refer to
Section 4.1
for instructions on how to utilize a pressure chamber to achieve the fill. The fill
pressure should not exceed 30 psi (2 bar)
5. Connect a hand pump to the fitting on the outlet side of the system, and apply vacuum, which
serves to pull the barrier fluid through the system.
6. Attach the incoming barrier fluid supply under pressure to the inlet side and verify that the
needle valve is open.
7. WAIT…. The process will take time. Higher pressure will not help and may cause
damage to the diaphragm. Maintain pressure on the inlet side and vacuum on the outlet
side to move the fluid through the system.
8. Observe the fluid at the outlet (vacuum pump) side. When clear, air free fluid is observed,
close the inlet side needle valve and remove the pressure source.
9. Replace the plug into the needle valve to seal the system inlet.
10. Allow vacuum to remain on the outlet side of the system for approx. 2-3 minutes, this will aid
in the evacuation of excess fluid. Once complete, release the vacuum and remove the hand
pump.
11. Attach a short section of tubing to the fitting on the outlet side to catch excess fluid as the
system setup is completed in the next steps.

12. Ensure that the eccentric box of the pump has been filled to the appropriate level with the
correct hydraulic fluid.
13. If the pump is not already hydraulically primed, re-prime it now using the appropriate
procedure for a standard Pulsa Series flat diaphragm pump. If the diaphragm was never
removed, this step should not be necessary. If a new diaphragm is being installed, the pump
will need to be re-primed.
