Characteristics of ZCQ type stainless steel self-priming magnetic pump

The ZCQ type self-priming magnetic drive centrifugal pump (referred to as self-priming magnetic pump) is a new product that has been developed based on the requirements of many users and incorporates new foreign technologies on the basis of the CQ type magnetic pump. After repeated research and testing by our technical personnel, its performance has reached the advanced level of similar foreign products. This pump replaces dynamic seals with static seals, ensuring that the overcurrent components of the pump are completely sealed, completely solving the problems of running, emitting, dripping, and leaking that cannot be avoided by other pump mechanical seals. The material of the pump body and overcurrent components is made of corrosion-resistant stainless steel, corundum ceramic PTFE graphite and other materials, which not only have CQ type functions but also integrate self-priming, without the need for bottom valves and drainage water.

The main application of ZCQ stainless steel self-priming magnetic pump

The ZCQ self-priming magnetic pump has a compact structure, beautiful appearance, small size, low noise, reliable operation, and easy use and maintenance. It can be widely used in chemical, pharmaceutical, petroleum, electroplating, food, film photography and printing, scientific research institutions, national defense industry and other units to pump acid, alkali, oil, rare and precious liquids, transitional liquids, volatile liquids, as well as supporting circulating water equipment. Especially for the pumping of flammable, explosive, and volatile liquids, this pump is more ideal.

Working principle of ZCQ stainless steel self-priming magnetic pump

The ZCQ self-priming magnetic pump adopts an external mixed axial return water pump body structure, which is composed of a suction chamber, a storage chamber, a volute shell, a return hole, a gas-liquid separation chamber and other components. After the pump is started, under the action of centrifugal force, the remaining liquid in the suction chamber and the air in the inlet pipeline are stirred by the impeller into a mixture of gas and water. The mixture enters the gas-liquid separation chamber through the volute shell, and as the speed slows down, it causes gas and water separation. The air is discharged from the pump outlet, and the liquid returns to the pump through the return hole. After multiple cycles, the air in the inlet pipeline is discharged, forming a certain degree of vacuum in the pump and achieving self-priming.

Installation of ZCQ type stainless steel self-priming magnetic pump

1. After unboxing, check the pump nameplate and verify whether the main parameters of the self-priming magnetic pump product are consistent with the usage requirements.

2. The self-priming magnetic pump should be installed horizontally, and the pump body should not bear the weight of the pipeline.

3. The pump and pipeline should maintain good sealing.
