Embodiments include a pump with venting and non-venting piston return, a pump with stirrer and direct feed mechanism, a pump with CAN system and self-diagnostics, a pump with heated housing and reservoir, a pump with stepper motor and overdrive control and a pump able to be used with a plurality of different types or of lubrication systems.
Claims20
A lubrication system comprising:
- a lubrication pump configured to pump lubricant toward points of lubrication;
- and
- a lubrication controller in communication with and configured to control the lubrication pump, the lubrication controller including a processor and a tangible, computer readable non-transitory storage medium including processor executable instructions for controlling the operation of the lubrication pump when executed by the processor, wherein the instructions include instructions for controlling the lubrication pump in a first state mode and controlling the lubrication pump in a second mode different from the first mode, wherein in the first mode the lubrication pump is controlled to pump lubricant through one of a progressive valve distribution system, a dual-line distribution system or an injector distribution system, wherein in the second mode the lubrication pump is controlled to pump lubricant through a different one of the progressive valve distribution system, the dual-line distribution system or the injector distribution system.
