Abstract: A lubrication pump includes a reservoir 2 for a supply of lubricant, the reservoir having an outlet 5 at its lower end. A motor 10 is situated within the reservoir 2 and a thermally-conducting heat distributor 19 is mounted in thermal communication with the motor 10 to extend outwardly beyond the motor in the region of the bottom of the reservoir 2. Heat produced by operation of the motor 10 is distributed by the heat distributor 19, thereby reducing temperature differences in the lubricant within the reservoir 2 and improving the flow of lubricant to the outlet 5.

Abstract: A lubrication pump includes a piston and cylinder pump assembly comprising a piston arranged for reciprocation within and relative to a cylinder and having a charging stroke and a discharging stroke, a motor drivingly connected to the piston and cylinder assembly and a priming means including a priming handle coupled to the piston and cylinder assembly. In order to reduce the risk of damage to the pump or parts of a downstream lubricant distribution system through excessively forceful use of a priming handle and to provide a visual indication of the operation of the pump, a resilient member is provided in the coupling between the priming handle and the assembly such that movement of the priming handle to move the piston relative to the cylinder through the discharging stroke can take place without corresponding movement of the piston relative to the cylinder by deformation of the resilient member.
