Installation

Fluid Supply Line

1.Use grounded, flexible fluid hoses (E). See Ground The System, page 10.

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 Data, page 22. For best results, always install the pump as close as possible to the material source. Minimize suction requirements to maximize pump performance.

Fluid Outlet Line

1.Use grounded, flexible fluid hoses. See Ground The System, page 10,

2.Install a fluid drain valve (F) near the fluid outlet.

3.Install a shutoff valve (G) in the fluid outlet line.
