ABSTRACT:
A pump apparatus for viscous material adapted to be portable and includes a pair of upright supports defining a rigid framework mounted on a pair of wheels for movement along a support surface, such as a building floor. A platform extends perpendicularly outwardly from the framework and is adapted to support a container of material. A carriage is slideably mounted on a pair of guide rails secured to the framework, and a winch and cable assembly allows an operator to raise and lower the carriage. The carriage mounts a linearly arranged motor, drive shaft and pump, with the pump having a downwardly extending, disk-like follower plate oriented parallel to the platform. When a container is placed on the platform, the carriage may be lowered to insert the follower plate so that it bears against the materials. The motor drives the pump, and, as the material is removed from the container and dispensed through a hose, the weight of the carriage, pump and motor drives the follower plate into the container. The motor is reversible and includes a two level pressure control for automatic operation.
