Description
A newer version of the FlowMaster pump was introduced in July of
2008. These units incorporate the following improvements:
* Bushing & plunger seals used along with elastomer cup seals for
longer life and better high temperature operation.
* A crankcase oil dipstick
* Hardened and ground section on the reciprocating tube for longer
life and better crankcase oil control.

pivot pin anchor.
* Improved pivot pin fastener with deeper Allen hex socket.
All of the improved parts can be used with the older model pumps,
so the upgraded parts and subassemblies will now be supplied
to repair older model pumps. Please see the “Maintenance and
Repair” section for a list of the new repair kits and their proper ap-
plication.

General Description
The Lincoln Industrial rotary A/C electric pump uses a 120-230
VAC dual voltage motor and a single stage planetary gear
drive. Grease output is proportional to the pump RPM.
The pump is primarily designed for centralized lubrication sys-
tems such as the Single Line parallel, Single Line Progressive
and Two Line systems.
The pump is driven by the rotary motion of the electric motor.
Rotary motion is converted to reciprocating motion through an
eccentric crank mechanism. The reciprocating action causes
the pump cylinder to move up and down. The unit is a positive
displacement double acting pump as grease output occurs dur-
ing both the up and down stroke.
During the down stroke, the pump cylinder is extended into the
grease. Through the combination of shovel action and vacuum
generated in the pump cylinder chamber, the grease is forced
into the pump cylinder. Simultaneously, grease is discharged
through the outlet of the pump. The volume of grease during
intake is twice the amount of grease output during one cycle.
During the upstroke, the inlet check closes, and one half of the
grease taken in during the previous stroke is transferred through
this pump. Contact the factory authorized warranty and service
center nearest you for repair or adjus®ents other than mainte-
