Installation
The Typical Installation shown in FIG. 4 is only a guide
for selecting and installing system components. Contact
your Graco distributor for assistance in planning a
system to suit your needs.
Tighten Fasteners Before Setup
Before using the pump for the first time, check and
retorque all external fasteners. Follow Torque
Instructions, page 18.
Tips to Reduce Cavitation
Cavitation in a diaphragm pump is the formation and
collapse of bubbles in the pumped liquid. Frequent or
excessive cavitation can cause serious damage,
including pitting and early wear of fluid chambers, balls,
and seats. It may result in reduced efficiency of the
pump. Cavitation damage and reduced efficiency both
result in increased operating costs.
Cavitation depends on the vapor pressure of the
pumped liquid, the system suction pressure, and the
velocity pressure. It can be reduced by changing any of
these factors.
1. Reduce vapor pressure: Decrease the temperature
of the pumped liquid.
2. Increase suction pressure:
a. Lower the installed position of the pump relative
to the liquid level in the supply.
b. Reduce the friction length of the suction piping.
Remember that fittings add friction length to the
piping. Reduce the number of fittings to reduce
the friction length.
c. Increase the size of the suction piping.
NOTE: Be sure the inlet fluid pressure does not exceed
25% of the outlet working pressure.
3. Reduce liquid velocity: Slow the cyclic rate of the
pump.
Pumped liquid viscosity is also very important but
normally is controlled by factors that are process
dependent and cannot be changed to reduce cavitation.
Viscous liquids are more difficult to pump and more
prone to cavitation.
Graco recommends taking all of the above factors into
account in system design. To maintain pump efficiency,
supply only enough power to the pump to achieve the
required flow.
Graco distributors can supply site specific suggestions
to improve pump performance and reduce operating
costs.

Installation
312877ZAD 9
Mounting
1. For wall mounting, order Graco Kit 24C637.
2. Be sure the mounting surface can support the
weight of the pump, hoses, and accessories, as well
as the stress caused during operation.
3. For all mountings, be sure the pump is bolted
directly to the mounting surface.
4. For ease of operation and service, mount the pump
so air valve, air inlet, fluid inlet and fluid outlet ports
are easily accessible.
5. Rubber Foot Mounting Kit 236452 is available to
reduce noise and vibration during operation.
6. 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.
Grounding
Pump: See FIG. 1. Loosen the grounding screw (GS).
Insert one end of a 12 ga. minimum ground wire (R)
behind the grounding screw and tighten the screw
securely. Do not exceed 15 in-lb (1.7 N•m). Connect the
clamp end of the ground wire to a true earth ground. A
ground wire and clamp, Part 238909, is available from
Graco.
Air and fluid hoses: Use only grounded hoses with a
maximum of 500 ft (150 m) combined hose length to
ensure grounding continuity.
Air compressor: Follow manufacturer’s
recommendations.
Fluid supply container: Follow local code.
Solvent pails used when flushing: Follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive
surface, such as paper or cardboard, which interrupts
grounding continuity.
Check your system electrical continuity after the initial
installation, and then set up a regular schedule for
checking continuity to be sure proper grounding is
maintained.
• The pump exhaust air may contain contaminants.
Ventilate to a remote area. See Air Exhaust
Ventilation on page 11.
• Never move or lift a pump under pressure. If
dropped, the fluid section may rupture. Always
follow the Pressure Relief Procedure on page 16
before moving or lifting the pump.
The equipment must be grounded to reduce the risk of
static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current.
Polypropylene and PVDF: Only aluminum,
conductive polypropylene, hastelloy, and stainless
steel pumps have a ground screw. Standard
polypropylene and PVDF pumps are not conductive.
Never use a non-conductive polypropylene or PVDF
pump with non-conductive flammable fluids. Follow
your local fire codes. When pumping conductive
flammable fluids, always ground the entire fluid
system as described.

Air Line
See FIG. 4, page 13.
1. Install an air regulator (C) and gauge to control the
fluid pressure. The fluid stall pressure will be the
same as the setting of the air regulator.
2. Locate a bleed-type master air valve (B) close to the
pump and use it to relieve trapped air. Be sure the
valve is easily accessible from the pump and
located downstream from the regulator.
3. Locate another master air valve (E) upstream from
all air line accessories and use it to isolate them
during cleaning and repair.
4. An air line filter (F) removes harmful dirt and
moisture from the compressed air supply.
5. Install a grounded, flexible air hose (A) between the
accessories and the 1/2 npt(f) pump air inlet (D).
Use a minimum 3/8 in. (10 mm) ID air hose.
Installation of Remote Pilot Air Lines
1. Connect an air supply line to the pump (A, FIG. 3,
page 11).
2. Insert 5/32 OD tubing into the push-to-connect
fitting on each pilot valve (113).
3. Connect remaining ends of tubes to external air
signal, such as Graco’s CycleFlo™(PN 195264) or
CycleFlo II (PN 195265) controllers.
Reed Switch
Pulse Count models are intended for use with
customer-supplied fluid management or inventory
tracking systems. Attach an M12, 5-pin female cable to
connect the reed switch to your data monitoring system.
See Manual 406824.
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious injury from
splashing.
NOTICE
Pilot supply pressure should not exceed 25-50% of
main air supply pressure. If pilot supply pressure is
too high, the pump could leak air or exhaust
excessive air at stall.
