DESCRIPTION
Model 1810
MANUAL CENTRO-LUBER,
GREASE PUMP
Series "G"
The 1810 Centro-Luber is a manually operated multiple stroke grease pump for use on machines where periodic manual
lubrication is acceptable. It is used as the pumping unit for a centrali ed lubrication system having a single line circuit of
Series SL-1, SL-32, or SL-33 Injectors. Injectors can be used in combination where bearing si es or lubricant requirements
indicate such a combination advantageous and most efficient.
Pump dispenses grease up through NLGI #1 and discharges an established amount (*.160 cu. in.) into the circuit for each
full stroke of the pump handle. A built-in cycle indicator in the pump shows completion of the lubrication cycle.
*Based on lubricants that are free of entrapped air. Lubricants that are specifically aerated will reduce output of pump.
Model 1810 has a spring loaded follower in the reservoir and is filled with a filler pump through a filler fitting.

TO FILL MODEL 1810 WITH FILLER PUMP
1) Use a manual filler pump to fill reservoir through the filler fitting in the
pump body. Attach coupler on delivery hose to filler fitting. Stroke filler
pump handle until lubricant weepage is noted at air vent hole in the
reservoir (lower portion of follower must rise beyond air vent hole to expel
entrapped air from lubricant).
NOTE: When filling the reservoir, caution should be used, as extreme
pressure can cause damage to reservoir and follower assembly.
) A strainer is behind the filler fitting to prevent foreign material from
entering the reservoir. Remove filler fitting to inspect and clean strainer
periodically.

TO PRIME SYSTEM
S PPLY LINES
After pump reservoir has been filled with recommended lubricant, turn vent plug counterclockwise one complete turn
and operate pump until lubricant flows freely from opening in vent plug to expel air pockets trapped between the pump
and the supply line connection. Tighten vent plug. Remove all plugs in dead ends of the injector manifolds and supply
lines. Operate pump until lubricant flows from any plug opening. Close opening with plug. Continue operating pump
until lubricant flows from another plug opening. Repeat this procedure until all supply lines are primed and plug openings
closed.
FEEDER LINES
Fill each feed line with lubricant before connecting lines to outlet of injectors and bearings. This will prevent having
to cycle each injector for every inch of feed line between injector and bearing.
INJECTORS
Check each individual injector for proper operation. Injector stem moves when injector discharges lubricant to bearing.
This may require cycling system several times. After checking injectors for operation adjust injectors for the volume
required for each individual bearing.

1st OPERATION
2nd OPERATION
OPERATION
The Centro-Luber System lubrication cycle consists of two
operations:
1st OPERATION
The outward stroke of the handle forces lubricant into
the supply line. As handle is operated, lubricant pressure
is built up until it reaches ,500 PSI. When this pressure
is reached, the indicator will move out to its extended
position exposing a red ring on the indicator stem. This
indicates that the necessary pressure needed to operate
the system has been reached and operation of pump
handle is no longer required.
Lubricant pressure built up in the supply line operates the
injectors which dispense a measured amount of lubricant
into the bearing.
2nd OPERATION
Release handle and return it to its normal position
against the reservoir. When handle is in this position
lubricant pressure in the system vents back into the
reservoir. handle must be released for pump to vent.
Operators hand, gripping the handle, prevents the pump
from venting between strokes. Injectors re-charge for
next lubrication cycle.

To adjust Vent Position of Handle loosen the 50531 Set Screw. Then unthread the 51003 Nut
approximately one full turn. The 13069 Eccentric Cam can then be moved to the desired vent
postion. Re-tighten nut and set screw.
NOTE: t may be necessary to try several positions of eccentric cam before desired venting
adjustment is obtained.
