Heated lubricant pump

A lubricant pump comprising:

• a pump base having an upper wall;
• a reservoir housing mounted on the pump base, the reservoir housing and the upper wall defining a lubricant reservoir;
• a first pump element at least partially disposed in the lubricant reservoir;
• a first heating element disposed in the lubricant reservoir to be exposed to lubricant within the lubricant reservoir, the first heating element disposed proximate the first pump element and below the first pump element, the first heating element disposed between the first pump element and the upper wall;
• a first recess formed in the upper wall, the first heating element is disposed in the first recess;
• a second pump element at least partially disposed in the lubricant reservoir;
• a second heating element disposed in the lubricant reservoir proximate the second pump element and between the second pump element and the pump base;
• a second recess formed in the upper wall, the second heating element disposed in the second recess, wherein the second recess is formed separately from the first recess;
• and
• a thermal switch disposed in the pump base and electrically connected to the first heating element and the second heating element and configured to control activation and deactivation of the first heating element and the second heating element.

A lubricant pump comprising:

• a pump base having an upper wall;
• a reservoir housing mounted on the pump base, the reservoir housing and the upper wall defining a lubricant reservoir, wherein a bore extends through the upper wall;
• a first pump element at least partially disposed in the lubricant reservoir;
• a first heating element disposed in the lubricant reservoir to be exposed to lubricant within the lubricant reservoir, the first heating element disposed proximate the first pump element and below the first pump element, the first heating element disposed between the first pump element and the upper wall;
• a thermal switch disposed in the pump base and electrically connected to the first heating element and configured to control activation and deactivation of the first heating element;
• a plug mounted to the upper wall within the bore, the plug fluidly separating a wet portion of the lubricant pump within which the lubricant is disposed and a dry portion of the lubricant pump, wherein the plug includes an upper face oriented into the wet portion, a lower face oriented into the dry portion, and an edge extending between the upper face and the lower face;
• and
• a power line extending between the thermal switch and the first heating element, the power line extending through a wire bore in the plug;
• wherein the edge of the plug interfaces with a sidewall of the bore to fluidly separate the wet portion and the dry portion.
