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.

An end cap assembly for a reciprocating air motor comprises a pilot valve and an end cap body. The pilot has a valve stem. The end cap body comprises a central bore for receiving an air motor rod, a valve bore in which the pilot valve is disposed such that the valve stem extends through the end cap body, and an air port extending through the end cap body. The air port has a contour to direct air toward the valve stem.

A hose reel () is supported by a mounting bracket () which can be attached on a vertical or horizontal surface and allow for 180 degrees of motion to allow the hose reel () to automatically swivel in the direction the hose () is being pulled. The bracket mechanism () consists of integral mounting bosses () on the hose reel enclosures (), a mounting bracket (), a tube () and a constraint device () on the tube (). The mounting bosses () on the hose reel enclosures () are designed to orient and constrain the mounting tube () to allow for the tube to be installed from either end of the hose reel. The constraining device () on the tube () locks into an integral opening () in the mounting bosses () to prevent tube () displacement in either direction.
