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. Rubber mounting
feet are supplied with the pump. They should be
used to mount the pump to a cart or to the floor.The
rubber mounts have 3/8-16 in. internal and external
threads that allow a variety of mounting options. The
mounts reduce noise and vibration during operation
and provide clearance for the sanitary inlet clamps.
•
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 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).
See Fig. 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. Do not con-
nect the coupler (D) to the fitting until you are ready
to operate the pump.
Installation of Remote Pilot Air Lines
1.
Refer to Parts Drawings. Connect air line to pump
as in preceding steps.
2.
Connect 1/4 in. O.D. tubing to push type connectors
(14) on air motor of pump.
3.
Connect remaining ends of tubes to external air sig-
nal, such as Graco’s Cycleflo (P/N 195264) or
Cycleflo II (P/N195265) controllers.
Fluid Suction Line
1.
Use flexible, grounded fluid hoses.
2.
For best sealing results, use a standard Tri-Clamp®
style sanitary gasket of a flexible material such as
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 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 32, 40, and 50 for
maximum suction lift (wet and dry).
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
By replacing the push type connectors, other
sizes or types of fittings may be used. The new fit-
tings will require 1/8 in. npt threads.
The air pressure at the connectors must be at
least 30% of the air pressure to the air motor for
the pump to operate.
