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 10.
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 236452 is available to
reduce noise and vibration during operation.
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 connec-
tors (14) on air motor of pump.
NOTE: by replacing the push type connectors, other
sizes or types of fittings may be used. The new fittings
will require 1/8 in. npt threads.
3. Connect remaining ends of tubes to external air
signal, such as Graco’s Cycleflo (P/N 195264) or
Cycleflo II (P/N195265) controllers.
NOTE: the air pressure at the connectors must be at
least 30% of the air pressure to the air motor for the
pump to operate.
Fluid Suction Line
D If using a conductive (Acetal) pump, use conductive
hoses (G). If using a non-conductive (polypropy-
lene or PVDF) pump, ground the fluid system. See
Grounding on page 5.
D The pump fluid inlet (R) is a 1” raised face flange.
See Flange Connections on page 8.
D 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.
D At inlet fluid pressures greater than 15 psi
(104 kPa, 1 bar), diaphragm life will be shortened.
D See the Technical Data on page 32 for maximum
suction lift (wet and dry).
Fluid Outlet Line
WARNING
A fluid drain valve (J) is required to relieve pres-
sure in the hose if it is plugged. The drain valve
reduces the risk of serious injury, including splash-
ing 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
Fig. 2.
1. Use grounded fluid hoses (L). The pump fluid
outlet (S) is a 1” raised face flange. Refer to
Flange Connections on page 8.
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.
