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.
Description
This plunger pump will pump up to 2.5 GPM
at 2500 PSI. It spins at 3400 RPM in a direct
drive system coupled with a gasoline engine.
The matching flange provides convenient
connection to most 3/4” shaft 1.1 - 5.5 HP
engines. The hollow shafted pump includes
a built-in pressure control valve, and
chemical injection system.

Special Note: Use only AR64545 for the XJ/SJ/BK/RMV Series pumps only: Do NOT change
oil. Use oil only to add if low. This oil is a specially formulated synthetic with special
additives for the demands of the XJ, SJ, BK and RMV pump series. No other oil is factory
approved for these pumps, and could result in pump failure.

General Safety Information
(continuted)
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. (This pump has an unloader
already built in).
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.
Special Features
Wet End
Manifold: Forged Brass: Strength
and no porosity - long life. Higher
hydrostatic pressures - safety. Unloader:

injector. Simple repair using a cartridge
replacement kit. Bolts: Three bolts,
6mm grade 8.8.
Valves: Ultra Form Cages: Durable,
strong, and long life. Poppets and
Spring: 303 series stainless steel. Valve
Seat: Brass with an external sealing o-
ring on both inlet and discharge valves.

and durable.
Drive End
Bearings: Oversized ball bearing
stabilizes the crankshaft and one needle
style thrust bearing absorbs the plunger
load and assures long radial plate life.
Crankcase: Precision die-cast, with
cooling fins for maximum heat
dissipation. The housing retains the
crankshaft bearing, oil seal and rear
wobble plate bearing support washer.
Crankshaft/Wobble Plate: Precision

3. Lift the head up and
away from the body.
NOTE: The packing
stacks will not always
stay in the head of the pump
when it is removed. Sometimes
one or more components of the
packing stack will come out of the
head and stay on the plunger.
4. To remove any
components that
stay on the plungers
simply twist back and
forth while pulling up.
(See figure 18)
5. Remove low pressure
seals insert screwdriver
under seal lip and lift
up. (See Figure 19)
6. Remove the piston guides

many factors. Water seals should be
replaced when water leak or a loss
of performance is noticed. Prompt
replacement of worn seals will insure
peak operating performance and
trouble free operation. The water
seals and their respective components
sometimes referred to as the packing
stack, will vary slightly between
models. But the constant between
models is that the packing stack will
consist of the following items:
Piston Guides - which usually house
the low-pressure seal
Low-Pressure Seals
Piston Guide O-rings
High-Pressure Seals
Support Rings
Torque Ratings Inch Pounds
(ft.lbs.)
Head 221 (19)

2. Run a 50% solution of a RV or
non-toxic/biodegradable antifreeze
through the pump.
3. Flush the pump with fresh water
before the next use.
4. In freezing conditions failure to
do this may cause internal pump
damage.
5. For long periods of storage in nonfreezing areas the solution will keep
the seals and O-rings lubricated.
Oil - AR64545 - Container is 4.5 fluid
ounces. Specially formulated for the
demands of the 5XA48 pump. See
parts breakdown.
NOTE: No other oil is factory approved
for this pump. Using any other oil
may result in Drive End Damage.
Winter or Long Time Storage
1. Drain all of the water out of the
pump.
