Mounting
Pump exhaust air may contain contaminants that can
contaminate the fluid supply. Ventilate to a remote
area. See Air Exhaust Ventilation on page 10.
•
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, air inlet, and fluid inlet and
outlet ports are easily accessible.
Air Line
Trapped air can cause the pump to cycle unexpect-
edly, which could result in serious injury, including
splashing in the eyes or on the skin, injury from moving
parts, or contamination from hazardous fluids. A
bleed-type master air valve (B) is required in the sys-
tem to relieve air trapped between this valve and the
pump.
See F
. 2, page 8.
IG
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 accesso-
ries is grounded.
a. Install an air regulator/filter assembly (C) and
gauge to control the fluid pressure. The fluid
outlet pressure will be the same as the setting of
the air regulator. The air line filter removes
harmful dirt and moisture from the compressed
air supply.
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.
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. Con-
necting 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.
2. Install a grounded, flexible air hose (A) between the
accessories and the 1/4 npt(f) pump air inlet. Use a
minimum 6.3 mm (1/4 in) 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.
Fluid Suction Line
1. Use flexible, grounded fluid hoses (F). The inlet fits
sanitary tubing of 1 to 1.5-inch OD.
2. For best sealing results, use an appropriate
tri-clamp-style or DIN-style sanitary gasket of a flex-
ible material such as EPDM or Buna-N.
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. Excessive inlet fluid pressure
IG
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.
4. For maximum suction lift (wet and dry), see Techni-
cal Data, page 26. For best results, always install
the pump as close as possible to the material
source.
