⑴ hydraulic diaphragm drive mechanism to transfer power from the motor worm and achieve deceleration rotation, prompting crankshaft, connecting rod mechanism for reciprocating metering pumps seller, generating hydraulic drive plunger. ⑵ stroke adjustment mechanism by the crankshaft, eccentric, adjusting nut, adjustment screw, adjust the hand wheel (handle), dial (pointer) and scale constituted by changing the eccentricity to achieve the relative stroke of the plunger. Diaphragm material: PTFE. Description: For metering pump flow part, transport a variety of corrosive media. PTFE diaphragm is suspended high strength, good toughness, fluorine resin, by molding, turning, a variety of diaphragm metering pumps use a styling made for metering pumps Changzhou City, Xiao source Machinery Co., Ltd. on. I take full advantage of the unique PTFE fatigue resistance and corrosion resistance, and high elastic rubber, the development of a variety of diaphragm and prolong the service life of the diaphragm. Metering pump characteristics We recommend (certification), metering pumps supplied by Changzhou City, Xiao source Machinery Co., Ltd .. Changzhou City, Xiao source Machinery Co., Ltd.
