Diaphragm pump


PURPOSE:To make it possible to improve diaphragm pump efficiency by equalizing the pressure within the suction side space of a feeding fluid to that within the suction side space of a hydraulic pump. CONSTITUTION:The pump head provided to a feeding fluid 8 by a pump action is made approximately equal to the difference between the pressure within a suction side space 9 and the discharge pressure of a hydraulic pump 1. This head is substantially equal to the difference between hydraulic pump 1 discharge pressure and suction pressure. Accordingly, even if the pressure within the suction side space of the feeding fluid 8 varies, the head of the hydraulic pump 1 is made almost equal to the head provided to the feeding fluid 8, allowing the pump efficiency to be improved.
