ことを特徴とする脈動減衰器付ポンプ。[Claims for Utility Model Registration] A pair of diaphragms that partition a drive chamber and a pump chamber are built into a rectangular plate-shaped body.
A diaphragm pump that alternately pressurizes and discharges the main fluid in two pump chambers by alternately supplying and discharging air to two drive chambers and reciprocating both diaphragms, and a square plate-shaped body. A pressure-sensitive actuating member consisting of a piston or a diaphragm is built in, and the main fluid discharged from the diaphragm pump is made to oppose the air through the pressure-sensitive actuating member. The diaphragm pump and the pulsation attenuator are connected by bolts by joining the side surfaces of each body. It has two sets of connection ports that communicate, one set of connection ports is a convex port that protrudes from the joint surface and is provided with an O-ring on the outer periphery, and a concave port that the convex port is fluid-tightly fitted with. Another set of connection ports is configured by a combination of a large-diameter planar port equipped with an O-ring and a small-diameter planar port smaller than the inner diameter of the O-ring. Pump with pulsation attenuator.
