FIG. 2. Vent exhaust air

Fluid Supply Line

See FIG. 3 and FIG. 4, pages 10 and 11.

1.Use grounded fluid supply lines (G). See Grounding, page 7.

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.

3.At inlet fluid pressures greater than 15 psi (0.1 MPa, 1 bar), diaphragm life will be shortened.

4.For maximum suction lift (wet and dry), see Technical Data, page 22.

Fluid Outlet Line

See FIG. 3 and FIG. 4, pages 10 and 11.

1.Use grounded fluid hoses (L). See Grounding, page 7.

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

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