1.
Install an air filter/regulator assembly (H). The
fluid stall pressure will be the same as the setting
of the air regulator. The filter removes harmful
dirt and moisture from the compressed air supply.
2.
Locate a bleed-type master air valve (G) close to
the pump and use it to relieve trapped air. Be
sure the valve is easily accessible from the pump
and located downstream from the regulator.
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious
injury from splashing.
3.
Locate another master air valve (J) upstream
from all air line accessories and use it to isolate
them during cleaning and repair.
4.
Install a grounded, flexible air hose (F) between
the accessories and the pump air inlet.

1.
Connect a grounded, flexible fluid hose (K) to
the fluid inlet port. The port on pumps with
aluminum, stainless steel, or cast iron fluid
sections is 3 in. npt(f) or 3 in. bspt. On pumps
with polypropylene, conductive polypropylene, or
PVDF fluid sections, the port is an 80 mm (3 in.)
raised face ANSI/DIN flange.
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 0.21–0.34 bar (0.02–0.03 MPa,
3–5 psi) should be adequate for most materials.
3.
For maximum suction lift (wet and dry), see
. For best results, always
install the pump as close as possible to the
material source. Minimize suction requirements
to maximize pump performance.

Connect a grounded, flexible fluid hose (N) to
the fluid inlet port. The port on pumps with
aluminum, stainless steel, or cast iron fluid
sections is 3 in. npt(f) or 3 in. bspt. On pumps
with polypropylene, conductive polypropylene, or
PVDF fluid sections, the port is an 80 mm (3 in.)
raised face ANSI/DIN flange.
2.
Install a fluid drain valve (L) near the fluid outlet.
3.
Install a shutoff valve (M) in the fluid outlet line.
