ABSTRACT:
A pump head quick connect assembly (10) includes a pump head (28) having a body (30) penetrated by a first locating pin (16), having a proximal end (18) and a distal end (20), and a second locating pin (22), having a proximal end (24) and a distal end (26). The proximal ends of the first and second locating pins are attached to a base plate (12). The first locating pin distal end and the second locating pin distal end project beyond the pump head body and are inserted into a first outer passage (48) and a second outer passage (50), respectively, defined by a face plate (70). The face plate further defines an internally-threaded center passage (52) that threadably receives a manually adjustable screw (38). As the center screw is tightened against the pump head body, the pump head body is forced against the base plate, thereby forming a seal and centering the pump head on the base plate to prevent cocking. Loosening this single screw permits the face plate and the pump head body to be quickly removed from the locating pins.
