DESCRIPTION
General Description
The Models 84050, 85243 and 85460 are pumping units
designed to operate centralized lubrication systems. They
have a high volume output, delivering 30 cubic inches of
lubricant per minute at typical Centro-Matic
®
pressures.
They are fully automatic when used with Model 85209
Control. Pump is double acting, dispensing lubricant on
both the UP and DOWN strokes. These units are designed
to be used with SL-1, SL-11, SL-32 and SL-33 series
injectors or a
combination of these. The difference between the two
models is that the 85460 is equipped with a follower and a
low level indicator.
Appropriate Use
•
The pumps on these units are exclusively designed to
pump and dispense lubricants using compressed air
only.
•
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.
PUMP OPERATION
Operation of 85209 with Model 85530 System
Controller
When Model 85530 times out, it will initiate a lube cycle.
The air solenoid is energized to deliver air to the pump and
air to the vent valve. Pump begins dispensing lubricant
through injectors to the bearings.
When all bearings have received lubricant, pressure rises
in the system to actuate the pressure switch. When
pressure switch actuates, the control is reset to de-energize
the solenoid valve cutting off air to the pump and vent valve.
Pump stops, pressure vents and pressure switch de-
actuates. Control begins timing toward next lube event.
INSTALLING THE PUMP
Place the unit in the approximate location making sure that
grease and air connections are accessible. Mark center
locations of the six holes at the bottom of the reservoir.
Then drill six 1/2” holes. The use of 7/16” bolts will offer
some flexibility in securing the reservoir to the equipment.
Lubricant outlet of pump should be connected to system with
suitable hose capable of 3,500 PSI working pressure. Air line
connection should be made with at least 1/4” I. D. hose
