Description
Models 434-3370 and 615-2220 are
pumping units designed to operate a
Centro-Matic lubrication system. Units
include a vent valve to relieve line
pressure to recharge injectors.
FlowMaster II rotary-driven hydraulic
pump includes pressure reducing valve,
flow control valve and solenoid
operated (24 V ) on and off valve.
FlowMaster II pump is fully automatic
when using system controller and
pressure switch. Pump is double acting,
dispensing lubricant on both UP and
DOWN strokes.
Unit is designed to be used with SL-V,
SL-V XL, SL-1, SL-11, SL-32 and SL-33
series injectors or a combination of
these.
Model 434-3370 includes a follower
plate and electronic float switch.
Model 615-2220 includes an
electronic float switch and mechanical
shut-off to prevent grease from
overfilling during the refill process.
WARNING

Do not exceed
3 000 psi (207 bar)
maximum supply
inlet hydraulic pressure or
3 500 psi (241 bar) maximum outlet
pressure.
Exceeding rated pressures could
result in death or serious personal
injury and damage to system
components.
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 (→ Table 1).
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,
lubrication cycle is initiated. Solenoid is
energized to deliver hydraulic 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. When pressure
switch actuates, control 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. Controller
begins timing toward next lubrication
event.

Operation with
mechanical
shut-off
When attached, a mechanical shut-off
system (MSO) integrates with bucket
pumps to prevent grease from overfilling
during refill process. System is designed
for bucket pumps with capacity of
60 lb (27 kg), 90 lb (41 kg), 120 lb (54 kg)
and 400 lb (181 kg).
As grease fills reservoir, follower rises
and lifts pivot arm, forcing body and
guide assembly closed. When body and
guide assembly closes, pressure
continues to rise in supply line causing
pump to stall. At that point, supply line
relief valve must be opened to relieve
pressure from system.
Refer to manual 404758 for
maintenance and operating
instructions if present.
