The self suction magnetic pump adopts external mixing axial return water pump body structure. The pump body is composed of suction chamber, liquid storage chamber, volute, reflux hole, gas-liquid separation chamber, etc. After the self-priming magnetic pump is started, under the action of centrifugal force, the remaining liquid in the suction chamber and the air in the liquid inlet pipeline are stirred into a gas-water mixture by the impeller. The mixture enters the gas-liquid separation chamber through the volute. As the speed slows down, the air is discharged from the liquid outlet of the pump, and the liquid returns to the pump through the backwater hole. After several cycles, the air in the liquid inlet pipe is exhausted A certain vacuum degree is formed in the pump to achieve self-priming effect. The self-priming magnetic pump replaces the dynamic seal with the static seal, which makes the flow passage parts of the pump in a completely sealed state. The self-priming magnetic pump thoroughly solves the problems of running, emitting, dripping and leaking which cannot be avoided by other mechanical seals.
Self priming magnetic pump is a new product which has been successfully researched and tested by engineers and technicians of our company on the basis of absorbing foreign new technology according to the requirements of users. The self-priming magnetic pump adopts magnetic transmission principle and hybrid structure. Compared with ordinary centrifugal pump, it can reflect self-priming, facilitate remote centralized control and implement automatic operation. Therefore, it is widely used, especially for those cases where the installation position of the pump is higher than the liquid level, the self-priming magnetic pump is the first choice.
The self suction magnetic pump has the characteristics of full sealing, no leakage and corrosion resistance. The self-priming magnetic pump is self-priming. It does not need bottom valve and irrigation water. The self-priming height is 4 meters. It can be widely used in petroleum, chemical, pharmaceutical, electroplating, printing and dyeing, food, scientific research and other units. It can pump acid, alkali, oil, rare precious liquid, toxic liquid, volatile liquid, as well as circulating water equipment, especially for the pumping of leakage, flammable and explosive liquid.
