Fluid Supply Line
1. Use grounded, flexible fluid supply lines
(G). See Grounding, page 8.
2. If the inlet fluid pressure to the pump is
more than 25% of the outlet working pres-
sure, the ball check valves will not close
fast enough, resulting in inefficient pump
operation. Excessive inlet fluid pressure
also will shorten diaphragm life. Approxi-
mately 3 - 5 psi (0.02- 0.03 MPa, 0.21-0.34
bar) should be adequate for most materi-
als.

3. For maximum suction lift (wet and dry), see
Technical Data, page 22. For best results,
always install the pump as close as possi-
ble to the material source.

Fluid Outlet Line
See F
1. Use grounded, flexible fluid hoses (L). See
2. Install a fluid drain valve (J) near the fluid
outlet.
3. Install a shutoff valve (K) in the fluid outlet
line.
