Installation
4. For ease of operation and service, mount the pump
so air valve, air inlet, fluid inlet, and fluid outlet ports
are easily accessible.
Tighten Fasteners
Before mounting and using the pump for the first time,
check and retorque all external fasteners. Follow
your pump. After the first day of operation retorque the
fasteners.
Ground the System
Mount 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.
•
Aluminum and stainless steel pumps have a
ground screw. Always ground the entire fluid sys-
tem as described below.
To avoid serious injury or death from toxic fluid or
fumes:
•
Ventilate to a remote area. The pump exhaust air
may contain contaminants. See Air Exhaust Ven-
•
•
Polypropylene pumps are not conductive and are
not for use with flammable fluids.
•
Never move or lift a pump under pressure. If
dropped, the fluid section may rupture. Always fol-
before moving or lifting the pump.
Follow your local fire codes.
Pump: See FIG. 3. Loosen the ground screw (N). Insert
one end of a 12 ga. minimum ground wire behind the
ground screw and tighten the screw securely. Connect
the clamp end of the ground wire to a true earth ground.

Installation
Solvent containers used when flushing: Follow local
code. Use only conductive metal containers, placed on a
grounded surface. Do not place the container on a non-
conductive surface, such as paper or cardboard, which
interrupts grounding continuity.
Polypropylene (3300P)
The fluid inlet and outlet manifolds each have a 3 in.
raised face ANSI/DIN center flange.
NOTICE
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 main-
tained.
Use even and opposite torque to connect to the
polypropylene manifold flange. Excessive uneven
force can damage the flange.
Stainless Steel (3300S)
Fluid Supply Line
The fluid inlet and outlet manifolds each have either
3 in.-8 npt or 3 in.-11 bspt ports.
2. If the inlet fluid 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. Excessive inlet fluid pressure
also will shorten diaphragm life. Approximately 3-5
psi (0.02-0.03 MPa, 0.21-0.34 bar) should be ade-
quate for most materials.
Air Line
1. Install an air regulator and gauge (C) 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.
the pump as close as possible to the material
source. Minimize suction requirements to maximize
pump performance.
Trapped air can cause the pump to cycle unexpect-
edly, which could result in serious injury from splash-
ing.
Fluid Outlet Line
3. Locate another master air valve (D) upstream from
all air line accessories and use it to isolate them
during cleaning and repair.
2. Install a fluid drain valve (F) near the fluid outlet.
3. Install a shutoff valve (G) in the fluid outlet line.
4. An air line filter (C) removes harmful dirt and mois-
ture from the compressed air supply.
Fluid Inlet and Outlet Ports
NOTE: Remove and rotate the center manifold(s) to
change the orientation of inlet or outlet port(s). Follow
5. Install a grounded, flexible air hose (A) between the
accessories and the 3/4 npt(f) pump air inlet.
Aluminum (3300A)
The fluid inlet and outlet manifolds each have a 3 in.
ANSI/DIN center flange with either 3 in.-8 npt or
3 in.-11 bspt internal threads.

Installation
To provide a remote exhaust:
Air Exhaust Ventilation
1. Remove the muffler (U) from the pump air exhaust
port (K).
2. Install a grounded air exhaust hose (S) and connect
the muffler (U) to the other end of the hose. Use
muffler PN 111897, sold separately. The minimum
size for the air exhaust hose is 1 in. (25 mm) ID. If a
hose longer than 15 ft (4.57 m) is required, use a
larger diameter hose. Avoid sharp bends or kinks in
the hose.
If pumping flammable or toxic fluids, you must vent the
exhaust away from people, animals, food handling
areas, and all sources of ignition. Follow all applicable
codes.
.
NOTICE
The air exhaust port is 1 npt. Do not restrict the air
exhaust port. Excessive exhaust restriction can
cause erratic pump operation and poor diaphragm
life.
3. Place a container (T) at the end of the air exhaust
line to catch fluid in case a diaphragm ruptures. If
the diaphragm ruptures, the fluid being pumped will
exhaust with the air.

Operation
Operation
NOTE: If fluid inlet pressure to the pump is more than
25% of outlet working pressure, the ball check valves
will not close fast enough, resulting in inefficient pump
operation.
Pressure Relief Procedure
Follow the Pressure Relief Procedure
whenever you see this symbol.
NOTICE
Excessive fluid inlet pressure can reduce diaphragm
life.
This equipment stays pressurized until pressure is
relieved manually. To help prevent serious injury from
pressurized fluid, such as splashing in the eyes or on
skin, follow the Pressure Relief Procedure whenever
you stop pumping and before you clean, check, or ser-
vice the equipment.
4. Place the end of the fluid hose into an appropriate
container.
5. Close the fluid drain valve (F).
6. Back out the air regulator knob (C), and open all
bleed-type master air valves (B, D).
1. Shut off the air supply to the pump.
2. Open the dispensing valve, if used.
7. If the fluid hose has a dispensing device, hold it
open.
3. Open the fluid drain valve (F) to relieve fluid pres-
sure. Have a container ready to catch the drainage.
8. Slowly increase air pressure with the air regulator
until the pump just starts to cycle. Allow the pump to
cycle slowly until all air is pushed out of the lines
and the pump is primed.
Flush the Pump Before First Use
The pump was tested in water. If water could contami-
nate the fluid you are pumping, flush the pump thor-
oughly with a compatible solvent. See Flushing and
NOTE: Use lowest possible air pressure to prime, just
enough to cycle the pump. If the pump does not prime
as expected, turn air pressure DOWN.
9. If you are flushing, run the pump long enough to
thoroughly clean the pump and hoses.
Start and Adjust the Pump
1. Be sure the pump is properly grounded. Refer to
10. Close the bleed-type master air valve (B).
2. Check fittings to be sure they are tight. Use a com-
patible liquid thread sealant on male threads.
Tighten fluid inlet and outlet fittings securely.
3. Place the suction tube (if used) in fluid to be
pumped.

At the end of the work shift and before you check,
adjust, clean or repair the system, follow the Pressure
Maintenance
Maintenance Schedule
Flushing and Storage
Establish a preventive maintenance schedule based on
the pump’s service history. Scheduled maintenance is
especially important to prevent spills or leakage due to
diaphragm failure.
•
Flush before fluid can dry in the equipment, at the
end of the day, before storing, and before repairing
equipment.
Lubrication
The pump is lubricated at the factory. It is designed to
require no further lubrication for the life of the packings.
There is no need to add an inline lubricator under nor-
mal operating conditions.
•
•
•
Flush at the lowest pressure possible. Check con-
nectors for leaks and tighten as necessary.
Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.
Always flush the pump and relieve the pressure
before storing it for any length of time.
Tighten Threaded Connections
Before each use, check all hoses for wear or damage
and replace as necessary. Check to be sure all threaded
connections are tight and leak-free. Check mounting
bolts. Check fasteners. Tighten or retorque as neces-
sary. Although pump use varies, a general guideline is
to retorque fasteners every two months. See Torque
