FlowMaster™ Rotary Driven Hydraulic Pump
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A newer version of the FlowMaster pump was introduced in July of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 lon-
ger 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
application.

General Description
The Lincoln Industrial rotary Hydraulic Pump is a fully hydraulically
operated grease pump. Grease output is proportional to the hy-

lubrication systems such as the Single Line parallel, Single Line
Progressive and Two Line systems. An integrated pump control

pressure. A 24 volt DC solenoid valve is also incorporated as a
method to turn the pump
on
and
off
. A 24 volt DC solenoid valve
with a manual override is standard.
The pump is driven by the rotary motion of the hydraulic mo-
tor. 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
