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A newer version of the FlowMaster pump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 re-
ciprocating 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 repair older model pumps.
Please see the Maintenance and repair
section, page 9 for a list of the new repair
kits and their proper application.

(16 gallon)
• 85481 - Pump for 60 pound drum
• 85482 - Pump for 400 pound drum
(55 gallon)
• 85483 - Pump for 5 gallon pail
• 274055 - Same as 85481 with solenoid
cable assembly
General description
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 previ-
ous stroke is transferred through the outlet
check and discharged to the outlet port.
Typical output of the pump is shown
on page 5.
Appropriate use
• All pump models are 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 in-
structions will result in loss of claims for
warranty and liability.
• Do not exceed 3,500 psi (241 bar) maxi-
mum supply inlet hydraulic pressure.
Exceeding the rated pressure may result
in damage to system components and
personal injury.
