Abstract
A lubrication unit for delivering lubricant in a system and a method for controlling the unit. The lubrication unit includes a reservoir, a motor, and a pump. The lubrication unit has a flow rate sensor mounted downstream from the pump for measuring a flow rate of lubricant. The lubrication unit includes a control unit operatively connected to the flow rate sensor and the motor for controlling operation of the motor. The control unit includes an input selector for selecting at least one characteristic selected from a group consisting of a volume and a flow rate of lubricant pumped by the pump. The control unit adjusts motor speed to obtain the selected characteristic.
