Datasheet #35992: DP1 Pump - Bijur Delimon

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.)
Technical Data

Maximum Air Pressure 140 psi (10 bar)
Minimum Air Pressure 40 psi (3 bar)
Maximum Delivery 15 GPm (60 l/min)
Air Inlet Thread 1/4” nPT (F)
Oil Outlet Thread 3/4” nPT (F)
Air Piston Diameter 2” (50mm)
Air Piston Stroke 4” (100mm)
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).

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 40 and 140 psi (3 and 10 bar), 90 psi
(6 bar) is 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.
2.
3.
Secure the pump in a vice in the horizontal position, clamping it on the provided pads along the
pump body (13).
To unscrew the suction tube (30) from the pump body (13), use a 46mm wrench on the milling of
the foot valve body (34) for stub pump (see drawing on right), or a rod in the holes of the foot
valve body (36) for long pump.
Remove the upper roll pin (21) located in the upper part of the connecting rod (20) and unscrew
the rod from the air piston (8) (see drawing on right).
Foot Valve
1.
2.
Gently attach the suction tube assembly to the vice and unscrew the foot valve body (34: stub
pump, 36: long pump) from the suction tube (30).
unscrew the nut (35), remove and clean the screw (31), the washer (32) and the valve body, and
replace if damaged. Assemble the pump following the previous instructions, reversing each step.
Upper Valve

2.
3.
unscrew the nut (28) from the connecting rod (20) and remove the washer (27), the valve body
(26) and O-ring (25), the washer (24) and the spring (23).
Clean these parts carefully. if any of them are damaged, replace them before reassembly.
Assemble the pump following the previous instructions, reversing each step.
Reversing Set and Air Motor

5.
6.
Secure the air motor body (13) in the vise and loosen the four screws (14) to remove the air
motor cylinder (1).
Check the upper spring (2) and the spring stop (3) inside the air motor cylinder (1). Replace
if damaged.
Remove the lower circlip (15) and muffler (16) and pull up the air motor assembly (4) until the
hole in air piston (8) is visible in the opening where the muffler was removed. insert a steel rod
(8 mm) in the hole to lock the piston.
use a prepared 17mm wrench to disassemble the air motor assembly (4) (see drawing on right).
Remove the air piston (8) and disassemble the circlip (9), the washers (10) and the air piston
seal (11). Check the piston for scratches and replace damaged parts.
Assemble the pump following the previous instructions, reversing each step.
Packing Set
1. Follow the above procedure for the air motor until the air piston (8) has been removed from the
air motor body (13).
2. Remove the circlip (18) and the packing set (17) from the air motor body (13) (see drawing on
right). Replace if damaged.
3. Assemble the pump following the previous instructions, reversing each step. (Note: The packing
set is directional. It is not marked and must be installed correctly or it will leak. Look carefully at
the inside diameter of the seal, you will see three components. The middle black ring that is split
is a bearing. Above and below it are the brownish Turcite® seals, these are made with a step, and
the step faces the oil. Confirm this by looking into the seal from both directions, from one side
you will not see the steps, and from the other you will; this is the side that faces the oil. See
drawing on right.)

Before starting any kind of maintenance
or repair, disconnect the compressed air
supply and open a downstream valve to
relieve the oil pressure.
