Fluid Supply Line

See F . 3.
IG
1. Use grounded fluid supply lines (G). See
Grounding, page 7.
2. If the fluid inlet 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 on page 19.

Fluid Outlet Line

See F . 3.
IG
1. Use grounded fluid hoses (L). The pump
fluid outlet is 1 in. npt(f). Screw the fluid fit-
ting into the pump outlet securely.
2. A fluid drain valve (J) is required in your
system to relieve pressure in the hose and
dispense valve. Install the valve close to
the pump fluid outlet.
3. Install a shutoff valve (K) in the fluid outlet
line.

Fluid Inlet and Outlet Ports

NOTE: Remove and reverse the manifold(s) to
change the orientation of inlet or outlet port(s).
Follow the Torque Instructions on page 15.
The fluid inlet and outlet manifolds each have
four 1 in. npt(f) or bspt threaded ports. Close
off the unused ports, using the supplied plugs.
