Abstract
A lubricant pump () and a method thereof are disclosed. The lubricant pump () includes a pump base () and a reservoir housing (). The pump base () and the reservoir housing () define a lubricant reservoir for storing lubricant. One or more pump elements () extend at least partially into the lubricant reservoir. Heaters () are disposed on the pump base () proximate the pump elements (). The heaters () are configured to heat the local area surrounding the pump elements (), to thereby reduce the viscosity of the lubricant at the pump elements (). The heaters () are electrically connected to a thermal switch () to control activation and deactivation of the heaters (). With the lubricant pump () and the method thereof, the thermal switch () can control the heater () based on air temperature rather than the temperature of the lubricant, so the viscosity of lubricant is well controlled.
