4.0 Product Description and Operation
4.3 Operation
The power needed to operate the BreakerLube is
supplied by an external electrical source that is
controlled through a momentary switch. The heavy-
duty electric motor drives the cam that pushes the
piston through the grease filled chamber and
discharged through the open check valve.

1-Cam, 2-Piston, 3-Spring and 4-Check Valve.
The spring returns the piston and the chamber is re-
filled. The closed check valve prevents the back flow
of grease.

By design, the BreakerLube is a low capacity pump.
The pump’s discharge rate is purposely metered for
small quantities only.
4.4 Operation of Low-level Control
The basic pump assembly comes standard equipped
with a low level control. When wired to a light or
alarm, the operator is signaled that the grease level
inside the reservoir has fallen below the minimum
mark.

Electromagnetic switch, 3-Control Arm
4.4.1 Low-level Control - Full Reservoir
Refer to Figure 4-6. The magnetic switch (1) and
control arm (3) are attached to the stirring paddle.
With the grease level above the minimum mark, the
control arm pivots the magnetic switch out of range of
the electromagnetic switch (2).
4.4.2 Low-level Control - Empty Reservoir
The control arm pivots outward when the grease level
falls below the minimum mark. The normally open
electromagnetic switch will close when the magnetic
switch passes over it. The closed switch illuminates
the dash lamp.
