SAFETY
Read and carefully observe these operating instructions
before unpacking and operating the pump! The pump must
be operated, maintained and repaired exclusively by persons
familiar with the operating instructions. Local safety regula-
tions regarding installation, operation and maintenance must
be followed.
Operate this pump only after safety instructions and this
service manual are fully understood.
This symbol indicates a potentially hazardous situation which,
if not avoided, could result in death or serious injury. Please
refer to the operation manual, section C8, page 298 series for

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 pro-
tection to prevent control burnout.
The FlowMaster pump is fully automatic when used with Model
85530 Controller and a pressure switch. The FlowMaster
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 SL-33 series injectors or a combina-
tion of these.
Models 85471, 85472 and 85473 all include follower plates
and low level indicators.

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 energized 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 pres-
sure switch actuates, the control is reset to de-energize 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 loca-
tions 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exibility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.
Be careful to connect the red electric motor lead to the positive
side of the circuit. The motor is polarity sensitive and will not
