Graco Injecto-Flo EO-3 User Manual

Injecto-Flo EO-3
Electric Operated Pumps

DESCRIPTION

The EO-3 pump package includes a 115 or 230 VAC motor direct
coupled to a gear pump and mounted on a 3.6 liter (7.6 pint)
plastic reservoir. Each is equipped with a low level switch and
rated for service up to 24 bar (350 psi) . Timer equipped models
include a built in pressure switch. On/off cycles on remote control
models are programmed by a remote timer or from a machine's
PLC where available.

When electrical power is applied to the pump motor, lubricant fl ow
pressurizes the system mainlines causing the piston distributors
to dispense a measured volume of lubricant to the bearing points.
Making of the pressure switch contacts (pressure switch equipped
models) or expiration of the on time causes power to be shut off
from the motor. This stops fl ow and permits the internal vent valve
to release mainline pressure which allows the piston distributors to

re-prime in preparation for the next lube cycle.
