System having removable lubricant reservoir and lubricant refilling station

A removable lubricant reservoir for use with a pump assembly, the pump assembly including a housing having a connector and a pump for pumping lubricant to a lubrication site, said pump having an inlet for receiving lubricant, said reservoir comprising:

• a tank having an interior adapted for holding lubricant and a bottom for retaining lubricant in the tank interior when the reservoir is removed from the pump assembly;
• a locking ring rotatably mounted on the tank for removably connecting the tank to the connector of the housing of the pump assembly;
• and
• an outlet positioned for fluidly communicating with the pump inlet when the tank is connected to the housing of the pump assembly.

A lubricant refilling station for refilling a lubricant reservoir removed from a pump assembly, the pump assembly including a lubricant pump for pumping lubricant from the reservoir and a housing having a connector for selectively connecting the reservoir to the pump assembly, the reservoir including a tank for receiving lubricant, a connector for selectively connecting the tank to the connector on the housing of the pump assembly, and a refill inlet on the tank for refilling the tank with lubricant, the lubricant refilling station comprising:

• a refill housing having a connector functionally identical to the pump housing connector;
• an inlet on the refill housing adapted for connection to a supply of lubricant;
• an outlet on the refill housing positioned to fluidly communicate with the reservoir tank refill inlet when the tank is connected to the refilling station connector;
• a lubricant supply;
• and
• a refilling pump fluidly connected to the lubricant supply and the inlet of the refill housing for pumping lubricant from the lubricant supply to the refill inlet of the tank when the tank is connected to the housing of the lubricant refilling station.
