DP556 Pump
55:1, Air-operated, Grease
General
The DP556 Pump is a compressed air-operated reciprocating piston pump. This high capacity demand
pump is compatible with mineral and synthetic grease and suitable for large installations with long
length piping supplying several fluid outlets simultaneously. This pump is mounted directly on 120 lb
and 400 lb drums.
Operation
This pump is self-priming. To prime it the first time, it is convenient to connect the air supply to the
pump while keeping the outlet gun opened and slowly increase the air pressure by using a pressure
regulator. Once grease starts flowing through all the outlets, the pump is primed. The pump starts to
pump when an outlet valve is opened, for example a grease control gun.
Technical Data
Maximum Air Pressure 140 psi (10 bar)
Minimum Air Pressure 42 psi (3 bar)
Maximum Delivery 7.25 lbs (3.2 kg/min) Free delivery at 100psi air inlet pressure, using NLGI #2 grease @ 70°F
Air Inlet Thread 1/2” NPT
Grease Outlet Thread 3/8” NPT
Air Piston Diameter 4.3” (110mm)
Air Piston Stroke 4-1/4” (100mm)
Installation
Mounting with Reinforced Cover
(Recommended)
It is recommended to install this pump on a
drum using a reinforced cover due to weight
considerations, but it is possible to install two
different ways. Mount with reinforced cover (part
#F418026 for 400 lb drum and part #F418025
for 120 lb drum). Insert pump through the cover
and fasten it with the enclosed screws. Insert the
pump through the bung opening and fasten the
cover onto the drum firmly.
Mounting with Cover Adapter
Mount with cover adapter (part #F360133)
and bung bushing (part #F410001). Fasten the
cover (part #F418026 for 400 lb drum and part
#F418025 for 120 lb drum) onto the drum and
screw the nut of the bung adapter securely into
the 2” bung opening of the cover. Insert the pump
through the nut and adjust it with the star nut to
the desired height.
Always keep fingers and hands away from
moving parts. Do not dent or damage the
riser tube.
Do not ever lay the pump on the floor or
allow the grease covered pump tube to
become contaminated in order to prevent
damage to the internal seals of the pump.

Typical Layout
The drawing below is a typical layout shown with all the recommended accessories for the pump to
operate correctly. The compressed air supply must be fixed between 40 and 140 psi (3 and 10 bar).
The recommended pressure is 90 psi (6 bar). 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. Secure the pump in a vice in the horizontal position, unthread the suction tube (53) from the
pump body (37) and pull out the tube until the pin (51) is visible.
2. Remove the pin (51) and unscrew the connecting rod (52) until it is loose. (See drawing on right.)
Air Motor
1. Unscrew the lift ring (1) and the jam nuts (2) of the stroke end rod (3), remove the spacing
sleeve (4) and the closing ring (5).
2. Unscrew the air cylinder assembly (6) from the air motor body (37).
3. Remove the circlips (29) and push the trip shoe spring (28) backwards.
4. Remove the spring seat (8), the inverter assembly and the trip shoes (26).
5. Unscrew the screws (13) and the nuts (17) and disassemble all the parts until the air gasket (23)
becomes accessible.
6. Take out the air piston assembly and the seals (31, 34).
7. Clean all the parts and replace if necessary. Lubricate the components with grease and assemble
the pump following the previous instructions, reversing each step.
Replace the Packing Set
1. Follow steps 1 through 6 of the air motor maintenance procedure.
2. To unscrew the outlet adaptor (40); thread a 3/8” fitting completely into the adaptor and pull
clockwise first to break the seal, then counter clockwise to loosen and remove it, or use a
pipe wrench.
3. Unscrew and remove the packing set from the air motor body.
4. Replace the packing set with a new one. Mount the outlet adapter using Loctite Red sealer on
its threads.
5. Clean and lubricate the air motor components carefully. Assemble the pump following the
previous instructions, reversing each step.
Clean or Replace the Upper Valve
1. Unscrew the suction tube from the foot valve tube (60), remove the pins (51) and unscrew the
connection nut (54) from the piston (57).
2. Clean the balls (55, 56) and the housing carefully.
3. Verify the piston (57) and the high pressure cylinder (59) for scratches/scoring and the o-ring
(58) for damage; replace if necessary. Assemble the pump following previous instructions,
reversing each step.
Clean or Replace the Foot Valve
1. Unscrew the nut (72) and remove the filter (71), unscrew the nut (70) from the priming rod (67)
and remove the primer (69).
2. Push the rod (67) inwards and unscrew the priming tube (68) from the foot valve tube using the
provided holes.
3. Take out the parts of the valve (62-65) and clean them carefully, replace if damaged. Assemble
the pump following previous instructions, reversing each step.
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 oil pressure.
Remove pin and unscrew connecting rod

The air piston rod (33) is scored. Inspect the air piston rod (33).
Replace if damaged.
Air is leaking through the air
outlet muffler.
The quad-rings (31, 35) are worn
or damaged or scored piston assembly.
Replace quad-rings (31, 35) and/or the
piston assembly.
