ABSTRACT:
A pump of the rotor/stator type for wet cementitious material includes a suction housing for receiving and directing the material into a rotor/stator combination for delivery to the location of use. The suction housing is in the form of a rectangular closed structure having a material receiving flange and enclosing coupling between a drive shaft and an end of a rotor. The housing includes top, bottom and side panels, one of which includes the aforementioned material receiving flange. Each of the panels is easily removed from the suction housing to facilitate cleaning and removal of material residue after use, as well as maintenance and repair of the pump. Cementitious material may be introduced through either the top, bottom or either of the side panels by appropriate positioning of the material receiving flange. The pump further includes a lubricant reservoir for lubricating the drive shaft to extend pump operating lifetime.
