Installation
Fluid Fluid Fluid Supply Supply Supply Line Line 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 29 . For best results, always
install the pump as close as possible to the
material source. Minimize suction requirements
to maximize pump performance.

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