Patent ID: 6926492

Claim:
A pump for cementitious material comprising: a sealed drive stage capable of imparting rotary motion; a rotor/stator mechanism including a rotor disposed within a stator for displacing cementitious material within and along the length of said stator as said rotor undergoes rotational displacement; a connector coupling said drive stage to said rotor/stator mechanism for rotationally displacing said rotor; and a sealed suction housing enclosing said connector and including front and aft walls adapted for connection respectively to said rotor/stator mechanism and to said drive stage and adapted to receive cementitious material, wherein rotation of said rotor by said drive stage draws cementitious material from said suction housing for displacement within and discharge from said rotor/stator mechanism, said suction housing including plural removable side plates for exposing said connector and an inner portion of said suction housing to facilitate cleaning and repair of the pump.
