Abstract

PURPOSE: To provide pulsation-free pumping action for two pump chambers which are partitioned by a diaphragm in a pump casing by allowing a pair of eccentric wheels to be driven eccentrically with a phase difference of 180° by the shaft of the pump, in the pump casing.
CONSTITUTION: A pair of eccentric wheels 14 are fitted around the pump shaft 7 which is axially supported rotatably onto a pump casing 1 through a bearing 8, separated in the axial direction and with a phase difference of 180° in the circumferential direction. Thus, a pair of eccentric wheels 14 are eccentrically driven with a phase difference of 180° by the shaft 7 of the pump in the pump casing 1, and the phases of the suction chamber Pi and the discharge chamber Pe which are formed in two pump chambers partitioned by a diaphragm 24 in the pump casing 1 are diverged by 180°, and the fluid transported under pressure from each discharge chamber Pe is joined, and the pulsation due to the divergence of phase of each fluid by 180° can be dissolved.
