*Based on lubricants that are free of entrapped air. Lubricants that are aerated will reduce output of pump.
The 83987 Pump is used as the pumping unit for a centralized lubrication system having a single line circuit of SL-1, SL-32 or
SL-33 Injectors. It dispenses grease up through N.L.G.I. No. 1.
It is an air operated single stroke pump requiring air for both forward and return stroke that discharges *2.15 cu. in. of lubricant
into the circuit for each pump stroke (Lubrication Cycle).
The total quantity of lubricant needed for the lubrication cycle of the system must not exceed the amount of lubricant discharged
per pump stroke.
Electrical Power Requirements:
220 Volts, 50 Hz., 25 Volt Amps. Max.
Solenoid inrush current,. 52 amps;
holding current,. 35 amps.
TO FILL RESERVOIR
Use a Manual Filler Pump 81834 to fill reservoir
AIR VENT
through the filler fitting in the pump body. Attach
coupler on delivery hose to filler fitting. Stroke filler
pump handle until lubricant weepage is noted at air
LUBRICANT
vent hole in the reservoir (lower portion of follower
RESERVOIR
must rise beyond air vent hole to expel entrapped air
from lubricant).

FITTING
NOTE: When filling the reservoir, caution should be
used, as extreme pressure can cause damage to reser-
voir and follower assembly.

SUPPLY LINES: After pump reservoir has been filled with recommended lubricant, turn vent plug counter-clockwise one complete turn
and operate pump until lubricant flows freely from opening in vent plug to expel air pockets trapped between the pump and the supply
line connection. Tighten vent plug. Remove all plugs in dead ends of the injector manifolds and supply lines. Operate pump until
lubricant flows from any plug opening. Close opening with plug.
Continue operating pump until lubricant flows from another plug
opening. Repeat this procedure until all supply lines are primed and plug openings closed.
FEEDER LINES: Fill each feed line with lubricant before connecting lines to outlet of injectors and bearings. This will prevent having to
cycle each injector for every inch of feeder line between injector and bearing.
INJECTORS: Check each individual injector for proper operation.
Injector stem moves when injector discharges lubricant to bearing.
This may require cycling system several times. After checking injectors for operation adjust injectors for the volume required for each
individual bearing.
