Low amp draw for compatibility with portable machines.
Smooth, quiet operation for sound sensitive areas.
Special Hi-Pressure and Lo-Pressure Seals offer
exceptional life.
RTP heat resistant liquid-end and Regulator.
Mechanically actuated plungers offer greater efficiency.
Optional direct-coupled motors for compact, easy assembly
or convenient belt-drive mounting.
Ready for initial start-up with oil in the crankcase.
INSTALLATION
Each pump comes with oil in the crankcase ready for start-up. CAT PUMPS
special premium grade, multi-viscosity crankcase oil should be used.
It is recommended to install this pump in a horizontal position with the oil
filler cap at the top. It is permissible to rotate the oil filler cap to the right
or left, however, some oil spitting may occur. A rubber plug is inserted
into the oil filler cap for shipping. This should be removed before operation.
Do not operate pump with plug in cap.
Flexible hose should be installed at the unloader ports. Connect a hose
equal to or one size larger than the inlet port at the bottom of the pump
body. Connect a high pressure hose to the regulator discharge port at the
side of the regulator. Connect a by-pass hose to the bottom port of the
regulator or unloader and run to drain or back to a “T” in the inlet line.
CAUTION: Do not over tighten the RTP pump or regulator body.

OPERATION
Once the inlet water supply is turned on and the pump is started, adjust
the regulator at the top with an allen wrench or turn adjusting cap on the
unloader to set system pressure. Do this in small increments until the
desired system operating pressure is reached.
The 1LX pumps are axial plunger pumps. Special direct-drive motors are
secured to the pump with a V-Clamp Mounting. The optional Drive
Mount Assembly is required for the belt drive 1LXB100 model.
The motor rotates the offset cam and guide plate which is connected to
the three plungers. Each plunger moves forward at a different stage of the
cam rotation, providing a smooth, forward, liquid flow through the pump.
On the back stroke, the liquid enters the inlet chamber and flows through
each inlet valve. As the forward stroke begins, the inlet valve closes.
On the forward stroke, the liquid goes through the seat and forces the
discharge valve open to allow the liquid out the regulator discharge port.

Changing Crankcase Oil:
1. Shut down pump and remove from power source.
2. Remove black oil filler cap. Turn pump body over and drain.
3. Fill with exactly 2.23 oz. (66 ml) of CAT PUMPS crankcase oil and replace
black oil filler cap.
NOTE: Change oil after each 500 hour interval.
Checking Oil Level:
1. Shut down pump and remove from power source.
2. Remove black oil filler cap.
3. Place dipstick in pump with one (1) flattened end into crankcase and the other
flattened edge flush with top of the port.
NOTE: All models come with a dipstick.
4. Remove dipstick. Oil level should be at the
top of the lower flattened rod.
5. Adjust oil level as needed. Replace black oil
filler cap.

chamber.
8. Remove washer and Hi-Pressure Seal (HPS) from each cylinder.
9. Using a reverse pliers, remove the cylinder from each manifold chamber.
CAUTION: Exercise caution as the reverse pliers may score HPS surface.
10. Separate the inlet/discharge seat from the cylinder.
11. Remove the inlet valve, o-ring and inlet spring from the each cylinder.
12. Using a pliers, remove discharge valve and spring from each manifold chamber.
Reassembly:
1. Examine the discharge valves and springs for wear and replace as needed.
Snap spring to each discharge valve.
2. Using a pliers, insert the discharge valve/spring assembly into the notches at
the bottom of the manifold.
3. Examine the inlet/discharge seats for wear and replace as needed. Install new
o-rings onto both ends of the inlet/discharge seats.
4. Examine the inlet valves and springs for wear and replace as needed.
5. Examine cylinders for wear and replace as needed.
6. Install inlet spring, then valve into each cylinder.
7. Lubricate the outer surface of both o-rings on each inlet/discharge seat, then
press inlet/discharge seat into each cylinder.
8. Press inlet/discharge seat and cylinder assembly into manifold chamber.
9. Examine HPS and replace as needed. Press HPS into each cylinder with
groove down.
10. Examine washer and replace as needed. Press washer into each cylinder with
beveled edge down.
11. Examine seal case and replace as needed. Press seal case into each manifold
chamber.
12. Examine LPS and replace as needed. Press LPS into each seal case with
groove down.
13. Examine seal retainer for wear and replace as needed. Install seal retainer into
each crankcase chamber.
14. Place hand over the end of the plunger guide plate to keep the ball, spring and
washer contained within the crankcase. Press crankcase into manifold.
15. Place manifold and crankcase assemblies into the crankcase cover.
16. Insert the three manifold screws and torque to 30 in/lbs.
17. Fill per instructions under CHANGING CRANKCASE OIL, Step 3.
