Mountings
•
Be sure the mounting surface can support the
weight of the pump, hoses, and accessories, as well
as the stress caused during operation.
•
For ease of operation and service, mount the pump
so the air valve cover (2), air inlet, and fluid inlet and
outlet ports are easily accessible.
Air Line
1.
Install the air line accessories as shown in F
IG
. 2.
Mount these accessories on the wall or on a
bracket. Be sure the air line supplying the accesso-
ries is grounded.
a.
Install an air regulator (C) and gauge to control
the fluid pressure. The fluid outlet pressure will
be the same as the setting of the air regulator.
b.
Locate one bleed-type master air valve (B)
close to the pump and use it to relieve trapped
air. See the
WARNING
above. Locate the other
master air valve (E) upstream from all air line
accessories and use it to isolate them during
cleaning and repair.
c.
The air line filter (F) removes harmful dirt and
moisture from the compressed air supply.
2.
Install a grounded, flexible air hose (A) between the
accessories and the 1/2 npt(f) pump air inlet (N).
Use a minimum 3/8” (9.5 mm) ID air hose. Screw an
air line quick disconnect coupler (D) onto the end of
the air hose (A), and screw the mating fitting into the
pump air inlet snugly. Do not connect the coupler
(D) to the fitting until you are ready to operate the
pump.
Fluid Suction Line
1.
Use flexible, grounded fluid hoses (G) where possi-
ble.
2.
For best sealing results, use a standard Tri-Clamp®
style sanitary gasket of a flexible material such as
Buna-N, Viton, or silicon.
3.
If the fluid inlet pressure to the pump is more than
25% of the outlet working pressure, the ball check
valves will not close fast enough, resulting in ineffi-
cient pump operation.
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 35 for maximum
suction lift (wet and dry).
Fluid Outlet Line
1.
Use flexible, grounded fluid hoses (L) where possi-
ble.
2.
For best sealing results, use a standard Tri-Clamp®
style sanitary gasket of a flexible material such as
Buna-N, Viton, or silicon
3.
Install a fluid drain valve (J) near the fluid outlet. See
the
WARNING
above, and F
IG
. 2.
4.
Install a shutoff valve (K) in the fluid outlet line.
CAUTION
The pump exhaust air may contain contaminants.
Ventilate to a remote area if the contaminants could
affect your fluid supply. See
Air Exhaust Ventilation
on page 10.
WARNING
A bleed-type master air valve (B) is required in the
system to relieve air trapped between this valve and
the pump. Trapped air can cause the pump to cycle
unexpectedly, which could result in serious injury,
including splashing in the eyes or on the skin, injury
from moving parts, or contamination from hazardous
fluids. See F
IG
. 2.
WARNING
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
. 2.
