PM3 Pump
55:1, Air-operated, Grease
General
The PM3 Pump is a compressed air-operated reciprocating piston pump designed for high pressure
greasing. These pumps are compatible with all types of mineral and synthetic greases (up to NLGI
grade 2 viscosity). These pumps can be supplied as separate components or as complete systems
with all the elements necessary for installation. These pumps can be mounted on mobile units as well
as on fixed drums and connected to a distribution line for single reel use.
Operation
This pump is self-priming. To prime it the first time, connect the air supply to the pump and slowly
increase the air pressure from 0 to the desired pressure using a pressure regulator, while keeping
the outlet valve opened. Once grease begins to flow through the grease gun/guns, the pump is
primed. (Note: It is important that the foot valve of the pump does not come into contact with
contaminated surfaces, such as a workshop floor, as it may become contaminated with dirt or
foreign particles that can damage the seals.)
Technical Data
Maximum Air Pressure 140 psi (10 bar)
Minimum Air Pressure 20 psi (1.5 bar)
Maximum Delivery 0.7 lb/min (21 cu.in./min)
Air Inlet Thread 1/4” NPT (F)
Grease Outlet Thread 1/4” NPT (F) (includes 1/2”-27 male conn)
Air Piston Diameter 2.75” (70mm)
Air Piston Stroke 1.5” (35mm)
Installation
These pumps must be mounted on drums using
covers fitted with a 2” bung. Loosen the star nut
(48a) of the bung adapter to remove the lower
nut (48c) and screw this into the 2” bung
opening of the cover. Place the star nut (48a)
and the three jaws (48b) on the suction tube.
Lower the pump through the opening and fasten
the assembly at the desired height. Secure the
cover to the drum with the thumbscrews.
Always keep fingers and hands away from
moving parts. Do not dent or damage the
riser tube.
Ensure that the mounting surface and
attachments are strong enough to
support the lift and pump assembly
during operation.

Typical Layout
See drawing below for typical layout with all the recommended accessories for the pump to operate
correctly. The compressed air supply must be fixed between 20 and 140 psi (1.5 and 10 bar), 90 psi
(6 bar) the recommended pressure. An air shut-off valve must be installed to be able to close the
compressed air line at the end of the day (if the air inlet is not closed and there is leakage in some
point of the grease outlet circuit, the pump will start automatically, emptying the container).

Maintenance
Separate the Air Motor from the Pump
1. Unscrew and remove the grease outlet adapter and the air inlet adapter. Remove the air
motor cover.
2. Mount the pump to a vise in horizontal position, securing it on the suction tube (47).
3. Unscrew the priming cylinder (60) from the priming filter head (57).
4. Unscrew the air motor body (15) from the suction tube (47) using a threaded rod or a pipe
wrench, and pull it out until it stops. The union nut (37) will be visible after cleaning the grease
from the rod.
5. Slide an open end wrench over the flats of the lower part of the air piston (36) and unscrew the
nut (59) and remove the washer (58).
6. Remove the large roll pin (38) located in the upper part of the union nut (37) and unscrew the air
motor body (15) from the suction tube assembly. (See drawing on right.)
Foot Valve
1. Unscrew the foot tube (53) with the priming filter (57) from the high pressure cylinder (51).
Attach the foot tube to the vise, unscrew the priming filter (57), remove the foot valve seat (56),
the foot valve assembly (55) and the valve washer (54).
2. Clean these parts, replace if damaged. Assemble the pump following the previous instructions,
reversing each step. (Note the position of (55 and 56) on page 5 – the mating surfaces are
ground flat and the conical surfaces are opposed.)
Pressure Check Valve
1. Insert a steel rod (ø4mm recommended) through the lower grease by-pass hole in the high-
pressure piston (44) and unscrew it from the grease valve body (40).
2. Clean the check ball (43) and its seat in the high pressure piston (44). If damaged, replace all the
affected parts.
3. If the high pressure piston (44) is scored, unscrew the high pressure cylinder (51) from the
suction tube (47) and from the foot tube (53) and replace it. Assemble the pump following the
previous instructions, reversing each step.
Inverting Set and Air Motor
1. Secure the air motor body (15) and loosen the five 4mm screws (29) to remove the air
motor dolly (1).
2. Slide an open-end wrench over the flats of the lower part of the air piston (36). With second
wrench unscrew the air piston nut (2) and remove the parts (2-5).
3. Pull the air piston rod (36) down and out of the air motor body (15).
4. Unscrew the toggle nut (27) from the air motor body (15) and remove the parts (23-27).
5. Unscrew the 3mm allen screws (22) and remove the parts (16-21).
Packing Set and O-ring
1. Follow the procedure for the air motor until the air piston rod (36) has been removed from the
air motor body.
2. Remove the packing set (32-35) and the seal O-ring (31). Replace these parts and clean the seat
of the seal O-ring (31).
Refer to page 5 for parts reference.
Before starting any kind of maintenance
or repair, disconnect the compressed air
supply and open a downstream valve to
relieve the grease pressure.
The high-pressure piston and cylinder
must always be replaced at the same
time; they are a matched set.
It is important that the packing set and
O-ring are mounted in the correct order:
First locate the O-ring in the correct
position inside the motor body and use a
dab of grease to hold it in position. Then
install the large and small packing set.
Unscrew intake filter tube from intake
filter head
Unscrew air motor body from suction tube
Unscrew nut, remove washer
Remove pin, unscrew air motor body

Troubleshooting
Symptom Possible Cause Remedy
The pump is not working or there is no
grease delivery.
Not enough air supply pressure. Slowly increase the air supply pressure.
Some outlet line component is clogged
or closed.
Clean or open the outlet circuit.
There are air pockets in the grease
inlet area.
Stir and compact the grease.
The pump begins to operate very fast. The drum is empty or the grease level
is beneath the suction tube inlet.
Replace the drum or lower the suction
tube until the inlet reaches below the
grease level.
The pump runs on continuously after
the grease outlet is closed.
There is a grease leak in some point of
the outlet circuit.
Verify and tighten or repair.
Contamination in the upper valve or in
the foot valve.
Disassemble and clean. Replace
damaged components.
Grease is leaking through the
outlet muffler.
The outlet adapter (62) is loose. Reinstall with Loctite #242
or equivalent.
Grease has by-passed to the air motor
caused by worn or damaged seals (33)
or seal O-ring (31).
Replace the worn or damaged parts.
Air is leaking through the
outlet muffler.
The sliding valve (19) does not close
correctly.
Disassemble and clean. Replace
damaged components.
The valve strap (20) or the toggle
spring (25) are damaged.
Replace damaged components.
The air piston (4) is damaged. Replace damaged components.
The O-ring (6) is damaged. Replace damaged components.
Reduction of grease. There are air pockets in the grease
inlet area.
Stir and compact the grease.
Contamination in the upper valve or in
the foot valve.
Disassemble and clean. Replace
damaged components.
Diminution of grease pressure. The high pressure cylinder (51) or the
high pressure piston (44) is scored.
Replace high pressure cylinder or the
high pressure piston.
