Description
General Description
The Lincoln Industrial FlowMaster Pump Model 85486 is a
fully hydraulically operated grease pump. Grease output is
proportional to the hydraulic input flow. The pump is
primarily designed for use in a 5 gallon pail or small
container.
The pump is driven by the rotary motion of the hydraulic
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
pump is a positive displacement
single acting pump
.
Grease output occurs during the up stroke of the pump.
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. During the up-
stroke, the inlet check closes, and the grease taken in
during the previous stroke is transferred through the outlet
check and discharged to the outlet port. Typical output of the
pump is shown on page 3, under Pump Performance and
Specifications.
Appropriate Use
The pump is exclusively designed to pump and dispense
lubricants using hydraulic power.
The maximum specification ratings should not be
exceeded.
Any other use not in accordance with instructions will
result in loss of claims for warranty and liability.
Do not exceed 450 PSIG (32 bar) maximum supply inlet
hydraulic pressure. Exceeding the rated pressure may result
in damage to system components and personal injury.
Specialized equipment and knowledge is required for repair
of this pump. Contact the factory authorized warranty and
service center nearest you for repair or adjustments other

Safety Instructions
This equipment generates very high grease pressure.
Extreme caution should be used when operating this
equipment 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.
