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 all mountings, be sure the pump is bolted
directly to the mounting surface.
•
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
Mount these accessories on the wall or on a
bracket. Be sure the air line supplying the
accessories 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).
See F
. 5. Use a minimum 3/8 in. (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 mat-
ing fitting into the pump air inlet snugly.
Fluid Suction Line
1.
Use flexible, grounded fluid hoses.
2.
For best sealing results, use a standard tri-clamp or
DIN style sanitary gasket of a flexible material such
as EPDM, Buna-N, fluoroelastomer, 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
inefficient pump operation.
4.
At inlet fluid pressures greater than 15 psi (0.1 MPa,
1 bar), diaphragm life will be shortened.
5.
See the
on page 32
for maximum suction lift (wet and dry).
NOTICE
The pump exhaust air may contain contaminants.
Ventilate to a remote area if the contaminants could
affect your fluid supply. See
on page 11.
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 hazard-
ous fluids. See F
In the step below, do not connect the
quick-disconnect coupler (D) on the air hose to the
mating fitting on the pump until you are ready to
operate the pump. Connecting the coupler too early
can result in unintentional operation of the pump,
leading to serious injury from moving parts,
splashing fluid in the eyes or on the skin, and
contact with hazardous fluids.
