Safety
Read and carefully obser e these operating instructions
before unpacking and operating the pump. The pump must
be operated, maintained and repaired exclusi ely by
persons familiar with the operating instructions. Local
safety regulations regarding installation, operation and
maintenance must be followed.
Operate this pump only after safety instructions and this
ser ice manual are fully understood.
Indicates a potentially hazardous situation which, if not
a oided, could result in death or serious injury.
Indicates a potentially hazardous situation which, if not
a oided, may result in minor or moderate injury.
Safety Instructions
This equipment generates ery high grease pressure.
Extreme caution should be used when operating this
equipment as material leaks from loose or ruptured
components can inject fluid through the skin and into the
body causing serious bodily injury. Adequate protection
is recommended to pre ent splashing of material onto the
skin or into the eyes.
If any fluid appears to penetrate the skin, get emergency
medical immediately. Do not treat as a simple cut.
Tell attending physician exactly what fluid was injected.
Description
General Description
This unit is a hydraulically operated, single acting, spring
return, positi e displacement pump designed to deli er
grease under pressure. The pump is primarily designed to
lubricate bushings of the tool bit in Hydraulic Hammers.
The pump can be used to lubricate bushings and bearings
on grippers and crushers. The pump is designed to be
directly installed on the hammer, gripper or crusher and
connected to the hydraulic power supply of the carrier.
Grease outlet of the pump should be connected by hose to
the point of lubrication.
The pump could be attached to an SSV di ider block for
multiple bearing lubrication.
The pump uses grease from standard 14.5 oz. grease
cartridges, eliminating the need for bulk filling equipment.
The pump may be filled from a bulk lubricant container if
desired.
The Grease Cartridge Housing is supplied with a Retainer
Clip (30) to pre ent the follower rod from protruding from the
reser oir while the pump is in operation. A Spring Clip (31)
is also pro ided to pre ent disengagement of the container
tube from the pump head in a high ibration en ironment.
Appropriate Use
This pump is exclusi ely designed to dispense grease in
Hydraulic Hammer and gripper/crusher applications.
It should be operated only with hydraulic power.
The maximum ratings gi en should not be exceeded.
Any other use not in accordance with the instructions will
result in loss of claims for warranty and liability.

Pump Operation
The pump operates simultaneously with the hammer.
Usually the carrier (exca ator, back hoe or skid steer) has a
foot pedal to operate the hammer. Each time the operator of
the carrier starts the hammer pushing the pedal, the pump
will make one stroke to dispense grease to the point of
lubrication. When operator stops the hammer, to reposition
or to start new work, the hydraulic pressure to the pump must
be ented and the springs (8, 9, and 10) will return the pump
plunger (6) into the initial position for the next lubrication
cycle. For proper pump operation, the inlet hydraulic back
pressure in the connecting hose has to be below 200 psig
(14 bar). As plunger opens the grease inlet port, grease
flows into the ca ity due to acuum in the ca ity and the
pressure exerted on the grease by the cartridge follower
spring (see Illustration 1).
Changing Pump Output
Pump is shipped with the metering plug (23) part number
270801, for minimum grease output - 0.018 in³ (0.3 cm³).
The output of the pump can be increased by changing the
metering plug (23):
-P/N 270802 -0.036 in³ (0.6 cm³)
-P/N 270803 -0.048 in³ (0.8 cm³)
-P/N 270804 -0.060 in³ (1.0 cm³)
-P/N 270805 -0.072 in³ (1.2 cm³)
Installing the Reservoir Retainer
Before installing the reser oir clip, make sure that the
Grease Cartridge Housing (28) and gasket (27) are in place
first. If grease cartridges are to be used, install a grease
cartridge in the Grease Cartridge Housing before final
adjustment of the spring clip.
Assemble the spring
clip (31) to the side of
the pump head (11) and
secure with the plate
(32) cap screws (34)
and lock washers (33)
as shown in the illustra-
tion. With the Grease
Cartridge Housing
installed, and securely
tightened (grease cartridge installed as required) adjust the
fingers of the spring clip so that they firmly retain the Grease
Cartridge Housing. The spring clip should be installed so
that the clip fingers pull the bottom of the groo e in the
Grease Cartridge Housing into the pump head. Tighten the
two cap screws (34).
Installing the Pump
The pump should be installed directly on the hammer or
gripper/crusher. Preferable mounting of the pump is
cartridge housing (28) in the upright position, but it may be
mounted in a horizontal position as well. Make sure to
allow sufficient space for cartridge remo al to refill and
pump ser icing. Mount in area where the pump indicator
cap (18) will be isible to monitor cartridge lubricant le el.
1. Use two 1/2 in. (12 mm.) bolts to securely mount the
pump on an e en and solid surface of the hammer. If
necessary, fabricate a mounting bracket.
2. Connect hydraulic power supply to the pump inlet (see
Illustration 2). Use appropriate high pressure hose.
3. Fill the pump with grease. (See Filling Pump with
Grease and Air Purging instructions.)
4. Attach the lubricant supply hose to the pump outlet.
5. Prime the supply hose with grease.
6. Connect lubricant supply hose to the lubrication point.
IMPORTANT: Low Le el indicator rod (14) will extend from
bottom of pump when grease cartridge becomes empty.
See illustration 2. Replace empty cartridge promptly with a
new grease gartridge.
Filling Pump ith Grease
Removing Empty Cartridge
1. Disengage the retaining clip from
the follower handle as shown in the
illustration, below.
2. Pull the spring clip of the reser oir
retainer by grasping the finger tab on
the clip and disengage the clip fingers
from the housing groo e. Loosen the
Grease Cartridge Housing a couple of
turns to break the seal.
3. Pull back the follower handle until the follower rod is fully
extended and latch the follower rod groo e into the slot in the
tube cap.
4. Unscrew the grease cartridge housing (28) from the pump
head (11).
5. Carefully release the follower handle to eject the empty
cartridge from the container tube.
Installing Grease Cartridge
1. Visually check follower seal lip direction before loading a
new cartridge. The follower seal lip must be directed toward
the follower handle for cartridge loading. See illustration be-
low. To change the direction of the follower seal, unscrew the
tube cap from the container tube and pull on handle to re-
mo e the follower seal from the tube. Flip the follower seal
o er and re-assemble.
2. Pull back on the follower handle and latch the follower rod
groo e into the slot on the tube cap.
3. Remo e the plastic cap from the grease cartridge and
insert the cartridge into the container tube.
4. Remo e the pull-tab from the grease cartridge. Pull the
finger tab on the spring retainer (31) back to clear the grease
cartridge housing (28) as the housing is placed into the open-
ing in the pump head (11). Screw grease cartridge-housing
(28) into the pump head (11) and tighten.
5. Release follower rod from slot. Purge air from pump. See
air-purging instructions.
6. Latch the retaining clip o er the top of the follower handle
to pre ent the follower rod from protruding from the grease
cartridge housing.
