Installation

Fluid Supply Line

See F . 4, page 13.
IG
1. Use grounded, flexible fluid supply lines (G). See
Grounding, page 9.
2. If the inlet fluid pressure to the pump is more than
25% of the outlet working pressure, the ball check
valves will not close fast enough, resulting in
inefficient pump operation. Excessive inlet fluid
pressure also will shorten diaphragm life.
Approximately 3 - 5 psi (0.02- 0.03 MPa, 0.21-0.34
bar) should be adequate for most materials.
3. For maximum suction lift (wet and dry), see
Technical Specifications, page 25. For best
results, always install the pump as close as possible
to the material source.

Fluid Outlet Line

See F . 4, page13.
IG
1. Use grounded, flexible fluid hoses (L). See
Grounding, page 9.
2. Install a fluid drain valve (J) near the fluid outlet.
3. Install a shutoff valve (K) in the fluid outlet line.
