Usage
Description
Models 85722, 85722MSO and 85723 are
pumping units designed to operate a Centro-
Matic lubrication system Units includes a
vent valve to relieve line pressure to recharge
injectors FlowMasterII rotary driven hydraulic
pump includes pressure reducing valve, flow
control valve and solenoid operated
(24 V ) "on" and "off" valve
FlowMasterII pump is fully automatic
when used with system controller and
pressure switch FlowMasterII pump is
double acting, dispensing lubricant on both
"up" and "down" strokes Unit is designed to
be used with SL-V, SL-1, SL-11, SL-32 and
SL-33 series injectors or a combination of
these injectors
Model 85722 includes follower plate and
mechanical low level indicator
Model 85722MSO includes follower plate,
mechanical low level indicator, and a
mechanical shut off
Model 85723 has no follower plate and no
low level indicator
Appropriate use
• Pump on unit is exclusively designed to
pump and dispense lubricants using
hydraulic power only
• Do not exceed maximum specification
ratings
• Any other use not in accordance with
instructions will result in loss of claims for
warranty and liability
WARNING

Do not exceed 3 000 psi (207 bar)
maximum supply inlet hydraulic
pressure or 3 500 psi (241 bar)
maximum outlet pressure
Failure to comply may result in
personal injury and damage to system
components
Operation with
system controller
Operation with lube system controller is
recommended System control must be
capable of operating hydraulic solenoid
valve, supplied with pump, and have
pressure detection or other means to
determine when lube event is complete
Pump and vent valve operation are
controlled automatically by single solenoid
valve supplied on pump manifold
System controller determines when lube
event starts and stops Time is used to start
lube event, and pressure signals to controller
that lube event is complete
In typical lube event, when system
controller times out, lube cycle is initiated
Solenoid energizes to deliver hydraulic
pressure to pump and vent valve
Pump begins dispensing lubricant through
injectors to bearings
When all bearings have received lubricant,
pressure rises in system to actuate pressure
switch As pressure switch actuates,
controller resets, de-energizing solenoid
valve, cutting hydraulic oil pressure to pump
and vent valve Pump stops, pressure vents
and pressure switch de-actuates
Controller begins timing toward next lube
event

Operation with
mechanical shut-off
When attached, a mechanical shut-off
system integrates with bucket pumps to
prevent grease from overfilling during refill
process System is designed for bucket
pumps with capacity of 60, 90, 120 and
400 lbs (27, 41, 54 and 181 kg) Refer to
404758 for maintenance and operating
instructions if present
