Abstract

See full text

A rotary positive displacement pump comprises a transmission housing having front and rear walls and rotationally supporting first and second drive shafts having constantly meshing gears such that the drive shafts rotate in opposite directions. A rotor casing connected to a front side of the housing has rear and front walls and a circumferential side wall defining an interior pumping cavity. The casing houses first and second rotors drivingly connected to the first and second drive shafts to provide a positive pumping effect on fluid product entering the cavity. The front and rear walls of the housing define an intermediate space through which the drive shafts extend. A first guard is located in the intermediate space and surrounds the drive shafts, or first and second guards are located in the intermediate space and surround the first and second drive shafts respectively, for protecting a person from contacting the drive shafts.
