    Tips: Difference between air operated diaphragm pump and self-priming pump

    Air operated diaphragm pump is a kind of pneumatic pump that uses diaphragm as the raw material medium. According to the motive force as the basis for classification, diaphragm pumps are divided into electric diaphragm pumps and pneumatic diaphragm pumps. Compared with ordinary water pumps, it has more advantages and simpler usage.

    The self-priming pump adopts an axial liquid return pump body structure. The pump body is composed of a suction chamber, a liquid storage chamber, a scroll chamber, a liquid return hole, a gas-liquid separation chamber, etc. After the pump is started normally, the impeller will suck the liquid in the chamber. It is sucked together with the air in the suction pipe and is completely mixed in the impeller. Under the action of centrifugal force, the liquid enters the gas and flows to the outer edge of the scroll. A white foam belt with a certain thickness and high speed is formed on the outer edge of the impeller. Rotating the liquid ring, the gas-liquid mixture enters the gas-liquid separation chamber through the diffuser.

    I would buy it again.
    Received this item just what I want! It is cheaper than many other same function diaphragm pump. I bought a stainless steel one, it is high performance and durable. I used this air operated diaphragm pump for discharge used oil. It worked great. I would buy it again.
