EO-1 lube packages consist of a 115 or 230 volt AC motor direct coupled to a gear pump and mounted on a steel or plastic reservoir. All are equipped with a low level switch as standard and are rated for service up to 40 bar (580 psi) . When electrical power is applied to the pump motor, lubricant flow pressurizes the system mainlines causing the piston distributors to dispense a measured volume of lubricant to the bearing points. De-energizing the pump stops flow and allows the internal vent valve to release mainline pressure. This allows the piston distributors to reprime in preparation for the next lube cycle. On/off cycles are achieved using a remote timer that has user selectable off and on times or control can be via the machine PLC where available and desired.
