DP1 Pump
1:1, Air-operated, Oil

General

The dP1 Pump is a compressed air-operated piston reciprocating medium pressure pump. Suitable
for high flow transfer of high viscosity lubricants and other fluids. These pumps can be supplied as
separate components or as complete systems with all the elements necessary for installation. These
pumps may be mounted on mobile units, drums, tanks or walls, using the appropriate accessories.
(Note: These pumps are designed and intended for transfer only and do not reliably stall under
pressure when used as a demand pump. They must be controlled with a valve on the air inlet.)

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 oil begins to flow through the oil gun(s), 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.)

Installation

The pump can be mounted directly on a drum or
on a wall bracket fitted with a 2" bung. Loosen
the star nut (29a) of the bung adapter to remove
the lower nut (29c) and screw this into the 2"
bung opening of the drum or bracket. Place the
star nut (29a) and the split collar (29b) on the
suction tube. Lower the pump through the
opening and fasten the assembly at the desired
height by tightening the star nut (29a).
