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 fl uid outlets simultaneously. This pump is mounted directly on 120 lb
and 400 lb drums.
Operation
This pump is self-priming. To prime it the fi rst 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 fl owing 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.

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 fi rmly.
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 fi ngers and hands away from
moving parts. Do not dent or damage the
riser tube.
Do not ever lay the pump on the fl oor or
allow the grease covered pump tube to
become contaminated in order to prevent
damage to the internal seals of the pump.
