ZCQF self-priming magnetic drive pump (referred to as magnetic self-priming pump) is a new product that applies the working principle of permanent magnet coupling to centrifugal pumps. It has a reasonable design, advanced technology, fully sealed, leak free, and corrosion-resistant characteristics, and its performance has reached the advanced level of similar foreign products.  

2、 Characteristics of self-priming pump products:
1. Magnetic self-priming pumps replace dynamic seals with static seals, ensuring that the overcurrent components of the pump are in a completely sealed state, completely solving the problem of mechanical seals that cannot avoid running, emitting, and dripping in other pumps. The magnetic pump uses corrosion-resistant and high-strength reinforced polypropylene, PTFE alloy, silicon nitride, carbon graphite, and steel jade ceramic magnets as manufacturing materials, and uses stainless steel connection frames to solve the problem of frequent replacement of connection frames due to environmental air corrosion for customers.
2. It not only has the function of CQF type magnetic drive pump, but also integrates self-priming, without the need for bottom valve and drainage water. It has good self-priming performance, short self-priming time, high efficiency, and can operate without liquid load. Its self-priming height is 4 meters, so it has good corrosion resistance and can protect the transported medium from pollution. Shanghai Yugong Pump Industry, a water pump manufacturer in Shanghai, welcomes new and old users to purchase.

3、 ZCQF type fluoroplastic self-priming magnetic pump Application:
The 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 solution, rare and valuable oil liquids, venom, volatile liquids, as well as supporting circulating water equipment and pass rate machines. Especially for the pumping of liquids that are prone to leakage, flammable, and explosive, this pump is more ideal for explosion-proof motors.
Working principle of self-priming pump:
This self-priming 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 completely discharged, forming a certain degree of vacuum in the pump and achieving self-priming.
