FlowMaster
®
Rotary Driven Electric Pump
Form 404059
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A newer version of the FlowMaster pump was introduced in July of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.
* Hardened and ground pivot pin bushings with a tighter fit into the
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 re-
pair older model pumps. Please see the “Maintenance and Repair”
section for a list of the new repair kits and their proper application.

General Description
The Lincoln Industrial rotary A/C electric pump uses a 50 Hz, 3
Phase 380-420 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 systems 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 during 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 pre-
vious stroke is transferred through the outlet check and discharged
to the outlet port. Typical output of the pump is shown on page 3.

Inspection
If overpressurizing of the equipment is believed to have oc-
curred, contact the factory authorized warranty and service
center nearest you for inspection of the pump.
Specialized equipment and knowledge is required for repair of
this pump. Contact the factory authorized warranty and service
This equipment generates very high grease pressure.
Extreme caution should be used when operating this equip-
ment as material leaks from loose or ruptured
components can inject fluid through the skin and into the
body causing serious bodily injury. Adequate protection is
recommended to prevent splashing of material onto the skin
or into the eyes.
If any fluid appears to penetrate the skin, get emergency
medical care immediately. Do not treat as a simple cut. Tell
attending physician exactly what fluid was injected.
