Abstract
A portable reciprocating pump assembly delivers lubricant from a reservoir and includes a housing mountable on the reservoir and a pumping tube assembly for directing lubricant from the reservoir and into the housing. The tube assembly has a reciprocating plunger and a shovel assembly attached to the lower end of the plunger and having a disk member and a valve. A drive mechanism for operating the pumping tube assembly is disposed within the housing and includes a drive shaft and a cam mounted eccentrically on the shaft and disposed within an opening of a follower. The follower is coupled with the plunger such that rotation of the drive shaft reciprocates the plunger along a vertical axis. A motor is connected with the drive shaft and actuates the drive mechanism and a battery provides power to the motor such that the pump assembly operates without connection to a separate power source.
