Installation
Mountings
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 8.
1.
Be sure the mounting surface can support the weight of
the pump, hoses, and accessories, as well as the stress
caused during operation.
2.
For all mountings, be sure the pump is bolted directly to
the mounting surface.
3.
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.
4.
Rubber Foot Mounting Kit 819.4333 is available to
reduce noise and vibration during operation.
Air Line
Warning
A bleed-type master air valve (B) is required in your 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 Fig. 2.
1.
Install the air line accessories as shown in Fig. 2. 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 mois-
ture 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. 3. Use a minimum 13 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 grounded fluid hoses (G). The pump fluid inlet (R)
is 1–1/2 in. bspt. Screw the fluid fitting into the pump inlet
securely.
2.
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.
3.
At inlet fluid pressures greater than 1.05 bar, diaphragm
life will be shortened.
4.
See the Technical Data on page 29 for maximum suc-
tion lift (wet and dry).
Fluid Outlet Line
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 seri-
ous injury, including splashing in the eyes or on the skin, or
contamination from hazardous fluids when relieving pres-
sure. Install the valve close to the pump fluid outlet. See
Fig. 2.
1.
Use grounded fluid hoses (L). The pump fluid out-
let (S) is 1–1/2 in. bspt. Screw the fluid fitting into the
pump outlet securely.
2.
Install a fluid drain valve (J) near the fluid outlet. See the
Warning above.
3.
Install a shutoff valve (K) in the fluid outlet line.
