Description
Model 85759 is a pumping unit designed to
operate a Centro-Matic lubrication system.
Unit includes a vent valve to relieve line
pressure to recharge injectors. FlowMaster II
rotary driven hydraulic pumps include a
pressure reducing valve, flow control valve
and solenoid operated (24 V
"off" valve. Pressure reducing and flow con-
trol valves are factory preset and are not
adjustable.
FlowMaster II pump is fully automatic
when using a system controller and a pres-
sure switch. Pump is double acting, dispens-
ing lubricant on both up and down strokes.
This unit is designed to be used with SL-V,
SL-1, SL-11, SL-32 and SL-33 series injec-
tors or a combination of these.
Model 85759 does not include a pressure
gauge.

Appropriate use
• Pump on this unit is exclusively designed
to pump and dispense lubricants using
hydraulic power only.
• Maximum specification ratings should not
be exceeded.
• Any other use not in accordance with
) "on" and
instructions will result in loss of claims for
warranty and liability.
WARNING
Do not exceed 3 500 psi (241 bar)
maximum supply inlet hydraulic
pressure or 3 500 psi (241 bar)
maximum outlet pressure.
Failure to comply may result in death,
personal injury and damage to system
components.

Operation with
system controller
When system controller times out, lube cycle
will initiate. Solenoid is energized 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. When pressure switch actuates, con-
trol is reset to de-energize solenoid valve
cutting off hydraulic oil pressure to pump
and vent valve. Pump stops, pressure vents
and pressure switch de-actuates. Control
begins timing toward next lube event.
