Appropriate use
Pump on unit is exclusively designed
to pump and dispense lubricant using
hydraulic power only.
Do not exceed psi (241 bar)
maximum specification. Do not exceed
maximum supply inlet hydraulic pressure.
Exceeding rated pressure may result in
personal injury or damage to system
components.
Any other use not in accordance with
instructions will result in loss of claims for
warranty and liability.
Operation with
system controller
When system controller times out, lubrica-
tion cycle initiates. Solenoid is energized to
deliver electric pressure to pump and vent
valve. Pump begins dispensing lubricant
through injectors to bearings.
When lubrication cycle has completed,
pressure rises in system to actuate pressure
switch. As pressure switch actuates,
controller is reset to de-energize solenoid
valve, cutting power to pump and vent valve.
Pump stops, pressure vents and pressure
switch de-actuates. Controller begins timing
toward next lubrication event.

Description
Model is a pump and reservoir
assembly designed to operate Centro-Matic
lubrication system. Unit includes vent valve
to relieve line pressure to recharge injectors.
Hydraulic pump and reservoir assembly
includes pressure reducing valve,
flow control valve and solenoid operated
(V ) on/off valve with manual
override. Pressure reducing and flow
control valves are factory preset and
are not adjustable.
Model does not include pressure
gauge, and is fully automatic when used with
system controller and pressure switch.
Pump is double acting, dispensing
lubricant on both up and down strokes.
Unit is for use with SL-V, SL-, SL-,
SL- and SL- series injectors.
