Cavitation depends on the vapor pressure of the

Pumped liquid viscosity is also very important but

Mount The Pump
To avoid serious injury from toxic fluid or fumes:
• Ventilate to a remote area. The pump
exhaust air may contain contaminants. See
Air Exhaust Ventilation, page 11.
• Never move or lift a pump under pressure. If
dropped, the fluid section may rupture. Always
follow the Pressure Relief Procedure, page 14,
before moving or lifting the pump.
1. Mount the pump so the exhaust port remains
clear of the production area. Exhaust air may
contain debris and condensation from the air
supply and air chamber.
Installation
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 secured
with screws through the mounting feet. Always
mount the pump upright.
4. Make sure the surface is flat and that the pump
doesn’t wobble.
5. For ease of operation and service, mount the
pump so air inlet, fluid inlet and fluid outlet ports
are easily accessible.

Ground The Sys
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 electrical current.
• Always ground the entire fluid system as
described below.
• The pumps are not conductive. Any system
used to pump flammable fluids must be properly
grounded.
• Follow your local fire codes.
Before operating the pump, ground the system as
explained below.
• Pump: Always ground the entire fluid system by
making sure the fluid has an electrical path to a
true earth ground.
• Air and fluid hoses: Use only flexible 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.

Air Exhaust Ventilation
If pumping toxic fluids, you must vent the exhaust
away from people, animals, food handling areas,
and all sources of ignition. Follow all applicable
codes.
NOTE: Do not restrict the air exhaust port. Excessive
exhaust restriction can cause erratic pump operation.

1. Use grounded, flexible fluid hoses (E). See
Ground The System, page 10.
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 inefficient 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 adequate for most
materials.

3. For maximum suction lift (wet and dry), see
Technical Data, page 29. For best results, always
install the pump as close as possible to the
material source. Minimize suction requirements
to maximize pump performance.
Fluid Outlet
1. Use grounded, flexible fluid hoses. See
Ground The System, page 10,
2. Install a fluid drain valve (F) near the fluid outlet.
3. Install a shutoff valve (G) in the fluid outlet line.

8. Apply medium-strength thread locker to the
threads of the second sleeve cap (3). Use the
tool (45) to install the second sleeve cap (3) into
the body. Tighten just until the cap is flush with
the surface. Do not overtighten.
9. If using new diaphragms, remove the thread
cover on each diaphragm (25†).
10. Tighten the pump shaft (5) onto one diaphragm,
hand tight only. Do not use any tools on the shaft.
11. Lubricate the shaft, then install it in the body.
Turn the diaphragm as you push it in. Then,
tighten the other diaphragm onto the shaft, hand
tight only.
5. Place a belleville washer (27) with the rounded
side toward the nut, then a flat washer (26) on
each tie bolt (24). Thread the first tie bolt (24)
through one fluid cover retainer (9), and then the
second tie bolt (24) through the other fluid cover
retainer (9). This necessary so that the first two
tie bolts come in from opposite sides to help keep
everything together before clamping.
6. Thread a fluid cover (6), the center section
assembly, the other fluid cover (6) onto the first
two tie bolts (24) and between the fluid cover
retainers (9).

11. Align the inlet manifold (10) on the assembly.
Orient the manifold so the inlet port is facing the
correct direction for your application (either the
same as, or the opposite from, the exhaust port).
12. Align the inlet manifold retainers (12). Place a
belleville washer (27), then a washer (26) on
each bolt. The rounded side of the belleville
washer must face toward the head of the
fastener. Install the bolts (29), just hand-tight for
now, then flip the pump over.
13. Assemble the top checks. Insert the seat (21†)
with the chamfered side up, the ball (22†), and
the outlet ball retainer (19†).
14. Carefully remove the manifold bolts (29) from
the top of the fluid covers (6), keeping nuts (18)
aligned.
15. Align the outlet manifold (8) with the dowels on
the top of the body.
16. Align the outlet manifold retainers (11). Place
a belleville washer (27), then a washer (26) on
each bolt. Install the bolts (29) hand-tight.
