DESCRIPTION
General Description
The Models 85471, 85472 and 85473 are pumping units
designed to operate a Centro-Matic® lubrication system.
The units include a vent valve to relieve the line pressure to
recharge the injectors. FlowMaster Rotary Driven Electric
Pump includes a motor speed control and built in circuit
protection to prevent control burnout.
The FlowMaster pump is fully automatic when used with
Model 85530 Controller and a pressure switch. The Flow-
Master pump is double acting, dispensing lubricant on both
the Up and Down strokes. This unit is designed to be
used with SL-1, SL-11, SL-32 and SL33 series injectors or a
combination of these.
Models 85471, 85472 and 85473 all include follower plates
and low level indicators.
Appropriate Use
 The pump on this unit is exclusively designed to pump
and dispense lubricants using 24 VDC power.
 The maximum specification ratings should not be
exceeded.
 Any other use not in accordance with instructions will
result in loss of claims for warranty and liability.
SYSTEM OPERATION
Operation with Model 85530 System Controller
When Model 85530 times out, it will initiate a lube cycle.
The solenoid and pump motor are energi ed to close the
electric vent valve and start the pump. Pump begins
dispensing lubricant through injectors to the bearings.
When all bearings have received lubricant, pressure rises in
the system to actuate the pressure switch. When pressure
switch actuates, the control is reset to de-energi e the
solenoid valve and motor. Pump stops, pressure vents and
pressure switch de-actuates. Control begins timing toward
next lube event.
INSTALLING THE PUMP
Place the unit in the approximate location making sure that
electric power connections are accessible. Mark center
locations of the six holes at the bottom of the reservoir.
Then drill six 1/2 (13 mm) holes. The use of
7/16 (11 mm) bolts will offer some flexibility in securing the
reservoir to the equipment.
Lubricant outlet of pump should be connected to system with
suitable hose capable of 3,500 PSI (241 bar) working
pressure.

Form 422733
Please refer to the 85567 operation manual, section C8, page
298, series A for setting the pump speed control on the
24VDC motor.
Low Level it (Model 85490)
Low Level Kit is recommended whenever higher viscosity
greases or lower temperatures are encountered and when
an external indicator of lubricant level is desired. The kit is
composed of a follower with wiper and a level indicator gage
located on the cover of the reservoir.
PUTTING PUMP INTO OPERATION
Filling Reservoir
 To bulk fill the reservoir, remove the lower and upper pipe
plugs from the side of the reservoir (see Figure 4). Attach
the appropriatebulk-filling pump to the lower inlet (3/4
NPT). Fill reservoir until grease appears at the top 1/2
NPT vent high level port.Remove the bulk-filling pump.
Replace both pipe plugs.
 To use the reservoir with a five-gallon pail of lubricant
(Model 85571 only), first remove the six bolts that secure
the lid. Remove the entire assembly of lid, pump and vent
valve. Using pipe wrench or vice grips, remove the filler
nipple extension (43) (View A-A) attached inside the
reservoir at the 3/4 NPT inlet nipple. Insert opened pail of
lubricant and reattach lid and pump assembly.
Note: If five gallon pail lubrication is to be used (for Model
85571 only), then the optional wing screws (38) should be
used in place of the hex bolt (10). Do not use follower
assembly with the 5 gallon pail.
specific areas of the check valve, vent valve or safety
unloader valve.
 Each part is identified with a number keyed to the
matching part on the illustrated views.
 General recommendations of tools required are also
specified in each step.
 Pay particular attention to the Warn ng statements to
prevent personal injury and possible damage to pump
components.
Outlet Check Service
(See Figures 1, 2, 7 & 8, Pages 5 & 6)
The pump will not build up sufficient lubricant pressure if the
outlet check (21) is fouled. Foreign material may lodge
beneath the Check Ball (49) or between check disc (46) and
the seat of bushing assembly (45). Sealing surfaces of the
seat must form a perfect seal. Clean parts or replace if
pitted, worn or scored.
1. Turn off and disconnect the electric powersupply to the
pump assembly.
2. Standard tools required are a bench mounted vice, a set of
open end wrenches ranging from 7/16 to 1-1/2, a large
24 (600 mm) adjustable wrench and a smaller 10
(254 mm) adjustable wrench.
3. Remove bolts, nuts and lock washers (25, 26 & 27).
4. Loosen adapter union (20). Set vent valve assembly to
the side.
5. Remove entire outlet check assembly (21) by loosening
adapter (22) from pump outlet.
6. Remove adapter (22) from outlet check assembly (21).
7. Remove outlet connector (50) from bushing (45).
8. Remove ball check seat (47) from outlet connector (50).
9. Inspect all check components (46, 45, 47 & 49) for
presence of foreign material, scoring and or other
damage, which may cause internal leakage. Replace
components if damage is found.
10. If foreign material is present, clean components and
reassemble. Be sure to always replace gaskets (44) &
(48) whenever vent valve is disassembled. Reverse the
above procedure to reassemble. Torque check
assembly to 100 ft.-lbs. (13.5 N-M).
Follower (see Figures 4, 5 & 6 Page 5)
If follower wiper appears to be damaged or does not wipe
the sides of the container effectively service may be
necessary.
1. Disconnect electric supply from pump.
2. Remove the eight bolts (10) and lock washers (9) which
attach the cover to the reservoir.
3. Lift the entire pump, vent valve, cover assembly and
follower out of the reservoir.
4. Unscrew the low level indicator (3) from the follower
plate (34).
5. Now remove the entire follower assembly from the pump
tube. After removing the follower assembly from the pump
tube wipe off the excess grease which will allow clean
access to the eight bolts that must be removed.
When filling the reservoir, caution should be used as
extreme pressure can cause damage to the reservoir or
serious personal injury.
MAINTENANCE & 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 be especially careful to
prevent any foreign matter from entering the grease pail or
contaminating the grease, as it adheres to the pump.
In Case of System Malfunction
(See Trouble Shooting Chart Page 8)
 Use the Trouble Shoot ng Charts to determine where to
look if problems occur.
 See the sections below for replacement and repair of

6. Loosen and remove the eight nuts (53) on top of the
follower.
7. Remove the follower weight and the wiper (51).
Replace the wiper with a new one.
8. Reassemble in the reverse of the above procedure
making sure that the long bolts are staggered with the
small ones and that they extend below the follower.
Low Level Indicator (see Figure 4 & 5 Page 5)
If the indicator pin appears to drop prematurely or water is
noticeable on top of the follower then the indicator seal (1)
may be damaged.
1. Remove the eight bolts (10) and lockwashers (9) which
hold the cover on to the reservoir.
2. Inspect the reservoir gasket seal (39) for damage.
If damage is apparent then replace the gasket seal.
3. Remove the entire pump, vent valve and follower assembly
from the reservoir.
4. Remove the retaining ring (82) from the indicator rod
assembly (3).
5. Hold the indicator plug (4) with a wrench while removing
the indicator nut (2).
6. Remove and replace the O-ring (1).
7. Reassemble in the reverse of the above procedure.
Torque the indicator nut (2) to 20 ft.-lbs.
Safety Unloader Valve
(See Figure 1 Page 5)
Safety unloader valve (28) is not serviceable and should be
replaced if malfunction is apparent. Upon reassembly,
tighten to 10 ft-lbs. (13.5 N-M).
The safety unloader (28) is set to open at 3,750 to 4,250 PSI
lubricant pressure. If pressure Switch fails to operate and shut
off hydraulic supply to pump, the Safety Unloader will open at
approximately 4,000 PSI to relieve lubricant supply line pressure
(Safety Unloader is preset and cannot be adjusted.)
Do not plug the outlet of the safety unloader. Plugging the
safety unloader outlet could result in pump damage and
serious personal injury.
