<strong>DP1</strong> <strong>Pump</strong><br />
1:1, Air-operated, Oil<br />
General<br />
The dP1 <strong>Pump</strong> is a compressed air-operated piston reciprocating medium pressure pump. Suitable<br />
for high flow transfer of high viscosity lubricants and other fluids. These pumps can be supplied as<br />
separate components or as complete systems with all the elements necessary for installation. These<br />
pumps may be mounted on mobile units, drums, tanks or walls, using the appropriate accessories.<br />
(Note: These pumps are designed and intended for transfer only and do not reliably stall under<br />
pressure when used as a demand pump. They must be controlled with a valve on the air inlet.)<br />
Operation<br />
This pump is self-priming. To prime it the first time, connect the air supply to the pump and slowly<br />
increase the air pressure from 0 to the desired pressure using a pressure regulator, while keeping<br />
the outlet valve opened. Once oil begins to flow through the oil gun(s), the pump is primed.<br />
(Note: It is important that the foot valve of the pump does not come into contact with contaminated<br />
surfaces, such as a workshop floor, as it may become contaminated with dirt or foreign particles<br />
that can damage the seals.)<br />
Technical Data<br />

Maximum Air Pressure 140 psi (10 bar)<br />
Minimum Air Pressure 40 psi (3 bar)<br />
Maximum Delivery 15 GPm (60 l/min)<br />
Air Inlet Thread 1/4” nPT (F)<br />
Oil Outlet Thread 3/4” nPT (F)<br />
Air Piston Diameter 2” (50mm)<br />
Air Piston Stroke 4” (100mm)<br />
Installation<br />
The pump can be mounted directly on a drum or<br />
on a wall bracket fitted with a 2” bung. Loosen<br />
the star nut (29a) of the bung adapter to remove<br />
the lower nut (29c) and screw this into the 2”<br />
bung opening of the drum or bracket. Place the<br />
star nut (29a) and the split collar (29b) on the<br />
suction tube. Lower the pump through the<br />
opening and fasten the assembly at the desired<br />
height by tightening the star nut (29a).<br />
29a<br />
29b<br />
29c<br />
Always keep fingers and hands away from<br />
moving parts. Do not dent or damage the<br />
riser tube.<br />
Ensure that the mounting surface and<br />
attachments are strong enough to<br />
support the lift and pump assembly<br />
during operation.<br />

Typical Layout<br />
See drawing below for typical layout with all the recommended accessories for the pump to operate<br />
correctly. The compressed air supply must be fixed between 40 and 140 psi (3 and 10 bar), 90 psi<br />
(6 bar) is the recommended pressure. An air shut-off valve must be installed to be able to close the<br />
compressed air line at the end of the day (if the air inlet is not closed and there is leakage in some<br />
point of the grease outlet circuit, the pump will start automatically, emptying the container).<br />

Maintenance<br />
Separate the Air Motor from the <strong>Pump</strong><br />
1.<br />
2.<br />
3.<br />
Secure the pump in a vice in the horizontal position, clamping it on the provided pads along the<br />
pump body (13).<br />
To unscrew the suction tube (30) from the pump body (13), use a 46mm wrench on the milling of<br />
the foot valve body (34) for stub pump (see drawing on right), or a rod in the holes of the foot<br />
valve body (36) for long pump.<br />
Remove the upper roll pin (21) located in the upper part of the connecting rod (20) and unscrew<br />
the rod from the air piston (8) (see drawing on right).<br />
Foot Valve<br />
1.<br />
2.<br />
Gently attach the suction tube assembly to the vice and unscrew the foot valve body (34: stub<br />
pump, 36: long pump) from the suction tube (30).<br />
unscrew the nut (35), remove and clean the screw (31), the washer (32) and the valve body, and<br />
replace if damaged. Assemble the pump following the previous instructions, reversing each step.<br />
Upper Valve<br />
1.<br />
2.<br />
3.<br />
unscrew the nut (28) from the connecting rod (20) and remove the washer (27), the valve body<br />
(26) and O-ring (25), the washer (24) and the spring (23).<br />
Clean these parts carefully. if any of them are damaged, replace them before reassembly.<br />
Assemble the pump following the previous instructions, reversing each step.<br />
Reversing Set and Air Motor<br />

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

Refer to page 5 for parts reference.<br />
Before starting any kind of maintenance<br />
or repair, disconnect the compressed air<br />
supply and open a downstream valve to<br />
relieve the oil pressure.<br />
Unscrew suction tube, remove rod<br />
Remove inverting set with 17mm wrench<br />
