4. At inlet fluid pressures greater than 15 psi (0.1 MPa,
1 bar), diaphragm life will be shortened. 5. See the Technical Data on pages 34 and 37 for
maximum suction lift (wet and dry).
Fluid Outlet Line
A fluid drain valve (J) is required to relieve pressure in
the hose if it is plugged. The drain valve reduces the risk
of serious injury, including splashing in the eyes or on
the skin, or contamination from hazardous fluids when
relieving pressure. Install the valve close to the pump
fluid outlet. See F
IG . 3.
1. Use flexible, grounded fluid hoses (L) where possi-

EPDM, Buna-N, fluoroelastomer, or silicon
3. Install a fluid drain valve (J) near the fluid outlet. See
