INSTALLATION
These pumps can be mounted directly on drums, tanks or on a wall
bracket (p.n. 360 102) fitted with a 2" bung (fig 2).
• Loose the star nut of the bung adaptor to remove the lower nut , and
screw this into the 2" bung opening of the drum or bracket.
• Place the star nut and the split ring on the suction tube.
• Slide the pump through the opening and fasten the assemble at the
desired height by tightening the star nut.
OPERATION
This pump is self–priming. To prime it the first time, you must connect
the air supply to the pump and slowly increase the air pressure from 0
bar to the required pressure using a pressure regulator, while keeping
the outlet valve (ex. an oil control gun) opened. Once oil starts to come
out the oil gun, the pump is primed.
TYPICAL INSTALLATION
See figure 3 for a typical installation with all the recommended accessories
for the pump to operate correctly.

NOTE: It is important that the foot valve of the pump is not in into
contact with dirty areas, such as a workshop floor, as it may be
contaminated with dirt or foreign particles that can damage the seals.
NOTE: The compressed air supply must be between 3 and 10 bar (40 –
140 psi), with 6 bar (90 psi) being the recommended pressure. An air
shut-off valve must be installed, in order to be able to close the
compressed air line at the end of the day. (If the air inlet not is closed
and there is a leakage at some point of the oil outlet circuit, the pump
will start automatically, emptying the container).
