FlowMaster™ Rotary Driven Electric Pump
Description
276041 - Pump for 5 Gal. Pail, speed range 9-93 RPM,
maximum 5,000 psi used on wayside rail lubricators.
General Description
The Lincoln Industrial rotary DC electric pump uses a 12VDC
motor and a two stage planetary gear drive. Grease output is
proportional to the pump RPM. The pump is primarily de-
signed 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 dur-
ing both the up and down stroke. The pump motor employs an
integral speed control capable of reducing pump speed to 10%
of its maximum value.
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 the outlet check and discharged to the outlet port.

Indicates a potentially hazardous situation which, if not
avoided, could result in death or serious injury.
Indicates a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury.
Safety Instructions
This equipment generates very high grease pressure.
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.
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 physical exactly what fluid was injected.
