AIR OPERATED GREASE PUMP
Series "F"
TO FILL RESERVOIR
Use Manual Filler Pump 81834 to fill reservoir
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 vent hole in the reservoir (lower portion of
follower must rise beyond air vent hole to expel
entrapped air from lubricant). NOTE: When filling
the reservoir, caution should be used as extreme
pressure can cause damage to reservoir and
follower assembly.
TO PRIME SYSTEM
SUPPLY LINES: After pump reservoir has been
filled with recommended lubricant, 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.
FEEDER LINES: Fill each feed line with lubricant
before connecting tines 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.
The total quantity of lubricant needed for the lubrication
cycle of the system must not exceed the lubricant
discharged per pump stroke.

*Based on lubricants that are free from entrapped air. Lubricants that are aerated will reduce output of pump. The
83668 Pump is used as the pumping unit for a Centralized Lubrication System having a single circuit of SL-32 or
SL-33 Injectors. It is an air-operated, single-stroke, spring-return pump that discharges .450 cu. in. into the
circuit for each pump cycle.

Summary

To Fill Reservoir

To Prime System

Supply Lines

Procedure to remove air from pump and supply lines by operating pump until lubricant flows from open ends.

Feeder Lines

Fill each feeder line with lubricant before connecting to injectors to prevent cycling each injector.

Injectors

Check each individual injector for proper operation after priming.

Operation of the Pump

Troubleshooting

Pump Loses Prime

Check lubricant supply; if still an issue, check for leaks in the 66250 Ball Check or 34445 Packing.

Pump Fails to Operate

Check air supply; failure of injectors to cycle may indicate a leak in the supply line.

Service Parts

Types of Installations

Mechanical Control

Controls lubrication frequency using machine motion via a three-way valve.

Electrical Control

Uses an electrical time switch to control the three-way solenoid valve for pump operation.

Manual Control

Operates the pump manually by opening/closing a three-way valve for a set duration.
