High Performance Pumps
Description
Plunger Pumps are designed for a wide variety of high
pressure washing applications. They are constructed
with die-cast bodies and feature a brass head. Internal
components include coated ceramic plungers for long life
and durability. Precision cast cooling fins are anodized for
maximum heat dissipation. Oversized needle bearings on the
drive side, and ball on the non-drive side together with the
precision supports assure positive alignment and centering
in relation to the crankcase. Valve cages of special designed
Ultra-Form provide positive seating and extended life. One-
piece connecting rods are special alloy aluminum, bronze
rods over 4,000 psi units, oversized for strength and load
disbursement. These pumps are designed for gasoline driven
systems.
Please read and save these instructions. Read carefully before attempting to assemble, install,
operate or maintain the product described. Protect yourself and others by observing all safety
information. Failure to comply with instructions could result in personal injury and/or property
damage! Retain instructions for future reference.

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 19mm
hex plugs. The inlet valves are located
on the inside portion of the head under
the seal assemblies and the discharge
valves are located on the top row of the
pump head.
Tools required: #8-32x” machine screw
and diagonal pliers, screw driver, 19mm
socket, ratchet, and torque wrench.
Discharge Valve
Removal:
1. Remove the valve
cap. (See Figure 5)
2. Inspect the valve
cap O-ring for any
damage, replace if
necessary.
3. Screw the machine screw
into the hole on top of the valve
cage (approx 1/8”). Using the
diagonal pliers grasp the screw at
the lowest reachable point. Using
the pump head as a base, push
down on the pliers, the
valve will lift out. (See
Figure 6)
4. Use a small probe to
move the poppet up
and down to assure that
the valve is functioning
properly and that no
debris is stuck in the
valve. (See Figure 7)
5. Inspect the valve o-ring
for any damage, replace
if necessary.
Discharge Valve Assembly:
1. Insert the valve
assembly squarely
into the port
pushing it into place
with a deap well
socket (you will feel
the valve assembly
seat). (See Figure 8)
3. Install the
valve cap
and torque

that some of the water
seals have stayed on the
plungers and some in
the head. To remove
the seals from the
plungers simple turn the
assemblies and pull off.
(See Figure 12)
4. If the seal assemblies
are in the head use
the channel lock
pliers to grab the
seal retainer on the
outside ring, twist
the retainer in either
direction (this is done to
free the retainer O-ring
which is stuck to the manifold) and
lift out. (See Figure
