Abstract
A reciprocating pump having: a pump body including a suction path and a discharge path for a fluid; a pair of diaphragms; pump shafts which are attached to tip end portions of the diaphragms; a pair of pump flanges which slidably support the pump shafts, and which are integrated with the pump body through connection bodies that are placed outside the diaphragms; connecting rods which connect connecting plates attached to projecting tip-end portions that are projected from the pump flanges in the pump shafts, to each other in a state where the connecting rods are passed through the pump flanges to be placed outside the diaphragms; and a cover cylinder. The connecting rods are slidably supported through slide bearings which are supported by the pump flanges.
