Installation
Mountings
CAUTION
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.
5. Prolonged exposure to UV radiation will degrade
natural polypropylene components of the pumps. To
prevent potential injury or equipment damage, do
not expose pump or the plastic components to direct
sunlight for prolonged periods.
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.
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 end of tubes to external air
signal, such as Graco’s Cycleflo (P/N 195264) or
Cycleflo II (P/N 195265) controllers.
NOTE:
the air pressure at the connectors must be at
least 30% of the air pressure to the motor for the pump
to operate.
Fluid Suction Line
•
If using a conductive (Acetal) pump, use conductive
hoses (G). If using a non-conductive (polypropylene
or PVDF) pump, ground the fluid system. See
•
The pump fluid inlet (R) is a 1” raised face flange.
See
•
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.
•
At inlet fluid pressures greater than 15 psi (104 kPa,
1 bar), diaphragm life will be shortened.
•
See the
Technical Data
on page 34 for maximum
suction lift (wet and dry).
Fluid Outlet Line
WARNING
1.
Use grounded fluid hoses (L)
. The pump fluid out-
let (S) is 1” npt(f). See Fig. 5. Refer to
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.
The pump exhaust air may contain contaminants.
Ventilate to a remote area if the contaminants could
affect your fluid supply. See
Air Exhaust Ventilation
A fluid drain valve (J) is required to relieve pressure
in the hose if it is plugged. The drain valve reduces
the risk of serious injury, including splashing 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.
