Fluid Supply Line
See F
IG
. 3 and F
IG
. 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 pressure, 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 F
IG
. 3 and F
IG
. 4, pages 10 and 11.
1. Use grounded fluid hoses (L). See Ground-
ing, page 7.
2. Install a fluid drain valve (J) near the fluid
outlet.
3. Install a shutoff valve (K) in the fluid outlet
line.
