Description
Plunger Pumps are designed for high-pressure industrial
washing applications. They are constructed of die-cast
bodies and feature a forged brass head with a bayonet
style sight glass in the rear and side covers. Internal
components include special solid ceramic plungers for long
life and durability. Precision cast cooling fins are anodized
for maximum heat dissipation. Oversized premium
tapered roller bearings and the precision supports assure
proper shaft alignment and maximum life. Valve cages of
special designed Ultra-Form provide positive seating and
extended life. Two-piece connecting rods are a special
alloy aluminum-based material oversized for strength
and load disbursement. These pumps are designed for
gearbox, belt drive, or flex coupled systems, with a 24mm
solid crankshaft.

General Safety Information
(continued)
Maximum water temperature is
140°F.
All positive displacement plunger
pumps must have a safety relief valve
installed on the discharge side of the
pump, this valve could be either an
unloader or regulator and must be of
adequate flow and pressure for the
pump.
Adequate protective guards must
cover all moving parts. Perform
routine maintenance on the pump and
components.
Use only components that are rated
for the flow and pressure of the pump,
this would include hose, fittings, safety
valves, spray guns etc.
Electric Drive Pumps
Your power supply must conform to the
system requirements.
The motor must be grounded. Use
GFCI plugs and receivers.
Do not handle the pump/motor with
wet hands.

Service Pumps
Servicing the Valves
The inlet and discharge valves in this
series pumps are all the same. The
valves are located under the six 27mm
hex plugs. The inlet valves are located
on the lower row and the discharge
valves are located on the top row of the
pump head.
Tools required: 27mm socket, ratchet,
needle nose pliers,
mechanics pick and
torque wrench.
Valve Removal:
1. Remove the valve
cap. (See Figure 5)
2. Inspect the valve cap
O-ring for any damage,
replace if necessary. (See
Figure 6)
Figure 5
3. Use the needle
nose pliers to
remove the valve.
(See Figure 7)
4. Use a small probe
to move the poppet
Figure 7
up and down to assure that
the valve is functioning properly
and that no debris is stuck in the
valve.
5. Using the mechanics pick remove
the valve seat O-ring and inspect
for any damage, replace if
necessary.
Valve Assembly:
1. Install the valve seat
O-ring squarely into
the bottom of the
manifold. (See Figure
8)
Figure 8
2. Insert the
valve assembly
squarely into the
port pushing it
into the O-ring.
3. Install the valve
cap and torque
to the proper
specification. (See Figure
9)
Figure 9
Servicing the Packings/Seals
To access the water seals for inspection
or replacement, you will first need to
remove the head of the pump.
Tools required: 8mm hex socket, ratchet,
(2) long screwdrivers, reversible pliers,
mechanics pick and torque wrench.

6. Squarely seat the
retainer into the
Figure 19
head and push with even
pressure until it snaps into position.
(See Figure 19)
Servicing the Plungers
If the plungers are not damaged they
do not need any servicing.
Tools required: 17mm socket, ratchet,
mechanics pick, taper blade gasket
scraper, thread sealant and torque
wrench.
NOTE: Be very careful when working
with the plungers, they are made from
ceramic which is brittle and can be
damaged.
Any time you remove a plunger it is
recommended you replace the slinger
washer, O-ring and top plunger washer.
The washers are a cushion for the
ceramic plunger and compress when
first used, O-ring will set to create a
seal and usually will not spring back
to its original shape. By not replacing
these parts you run the risk
of breaking a plunger or
having a water leak.
Disassembly:
1. Remove the plunger
retainer nut. (See
Figure 20)
2. Insert the gasket
scraper between the
copper washer and
plunger to remove the
washer. (See Figure
21)
Figure 20
Figure 21
3. Twist and pull the
plunger off the
plunger rod. (See
Figure 22)
4. Remove the
Figure 22
plunger rod O-ring seal
and split back-up ring with the
mechanics pick.
5. Remove the brass slinger. At this
point clean any thread locker that
is left on the plunger rod and
retaining nut threads.
