IMPORTANT:
Pump must be installed in a vertical position.
OPERATION OF THE PUMP
Lubricant in the 247210 Translucent Reservoir
flows into the cavity in the 247484 Bushing and
Plunger Assembly.
Compressed air entering the bottom of the
247476 Air Cylinder (1/4" N.P.T. female) moves
the 247478 Piston upward. As the piston
moves upward, the plunger is also moved
upward into the bushing. As the plunger moves
upward, it moves the charge of lubricant from
the bushing cavity through the 84175 Outlet
Check to the outlet of the pump.
When the air pressure to the 247476 Air Cylinder
is relieved, the 247481 Piston Spring moves the
piston and plunger downward. In its extreme
down position, the plunger has retracted below
the bushing port, permitting lubricant to flow into
the bushing cavity.

WHAT TO DO IF:
P
ump loses prime. - Check lubricant supply.
System fails to cycle and calculated system planning has been followed. -- Lubricant may be leaking by the 66250
Ball Check or the 34445 Packing in the 84175 Check and Vent Assembly. Remove these parts and examine for
presence of foreign particles. Clean, or replace parts if worn or damaged.
Pump fails to operate. - Check air supply. Failure of Injectors to cycle can be caused by a leak in the supply line.
