Abstract
A mechanical actuated diaphragm pump for pumping fluids. The pump includes a pump housing having a chamber, a flexible diaphragm forming at least a portion of one wall of the chamber, a reciprocally movable member for causing reciprocal movement of a portion of the diaphragm, a rotating shaft connected to the reciprocally movable member such that rotation of the shaft causes reciprocation of the reciprocally movable member and a motor having an output shaft for driving the rotating shaft. The motor can be alternatively and selectively mounted with respect to the pump housing in a first alternative position such that the output shaft of the motor is fixed to the rotating shaft to drive the rotating shaft, and in a second alternative position such that the output shaft is connected to the rotating shaft through a pair of pulleys to drive the rotating shaft.
