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 reciprocally moving member and the motor may be attached by an Oldham coupling.
