Usage
Description
Models , MSO and  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
( 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-, SL-, SL- and
SL- series injectors or a combination of
these injectors.
Model  includes follower plate and
mechanical low level indicator.
Model MSO includes follower plate,
mechanical low level indicator, and a
mechanical shut off.
Model  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.
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 , ,  and
 lbs (27, 41, 54 and 181 kg). Refer to
 for maintenance and operating
instructions if present.
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.

Installation and operation
Installation
Place unit in approximate location making
sure electric and hydraulic power
connections are accessible.
 Mark center locations of six holes at
bottom of reservoir.
 Drill six 1/2in (13 mm) holes. Use of
7/16 in (10 mm) bolts will offer some
flexibility in securing reservoir to
equipment.
 Connect lubricant outlet of pump to
system with suitable hose capable of
  psi (241 bar) working pressure.
 Hydraulic inlet connection should be made
with at least 3/8in (9 mm) inner diameter
hose capable of at least
  psi (207 bar) operating pressure.
 Hydraulic return to tank connection line
should be 3/4in (19 mm) inner diameter
hose or pipe.
Refer to  for setting pump pressure
and flow control.
Pump operation
Filling reservoir
To bulk fill reservoir:
 Clean area around filling port.
 Remove lower and upper pipe plugs from
side of reservoir.
 Attach appropriate bulk-filling pump to
lower inlet ( in NPT).
 Fill reservoir until grease appears at top
 1/4in NPT vent high level port.
 Remove bulk filling pump.
 Replace both pipe plugs.
WARNING
Use caution when filling reservoir.
Extreme pressure can cause damage to
reservoir or serious personal injury.
Fill reservoir
(MSO equipped)
Body and guide assembly (),
pivot arm (), supply line relief,
follower () and cover () work in combi-
nation with each other to prevent grease
from overfilling reservoir during refill
process († fig. IPB , page  and
fig. IPB , page ).
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.
Operational procedure
 Verify relief valve is closed.
 Turn supply pump on.
 Supply pump stalls when gauge reaches
maximum.
 If grease level sensor or indicator option is
available with system, verify reservoir is
full of grease.
 Turn off supply pump.
 Open pressure relief valve to vent down
stall pressure. Make sure relief valve is
open long enough to remove pressure
from system.
 Disengage quick disconnect.
 Cap quick disconnect ends to prevent
contamination.
 Leave relief valve open until next fill cycle.


Maintenance and repair
General maintenance
• Keep area around pump clean. Clean off
filling port area prior to filling reservoir.
Clean area around filler after filling as
lubricants will attract dirt.
• Keep lubricants clean and free of dirt
and debris.
• When replacing grease pails prevent any
foreign matter from entering grease pail
or contaminating grease, as it adheres
to pump.
