The ZMD fluoroplastic magnetic self-priming pump replaces the dynamic seal with a static seal, which makes the overflowing parts of the pump in a sealed state, which solves the unavoidable disadvantages of running, dripping, dripping and leakage in the mechanical seals of other pumps. The materials of the pump body and overflowing parts are made of corrosion resistant stainless steel, ceramic, tetrafluorographite, carbon graphite, cemented carbide and other materials, which not only has the function of the pump, but also integrates self-suction, without bottom valve and water diversion. Open and smoke, easy and convenient. A rubber valve plate is arranged between the water inlet joint and the pump body, which closes automatically when it stops, keeping the pump full of liquid for the next time. Rubber sealing rings are used at the liquid outlet and inlet, and mechanical seals are used for sealing on the rotating shaft.

The residual liquid in the suction chamber and the air in the liquid intake pipeline are stirred into a gas non-mixture by the impeller, and the mixture enters the gas-liquid separation chamber through the volute, which leads to the separation of gas and water, the air is discharged from the pump outlet, and the liquid is returned to the pump through the backwater orifice. after many cycles, the air in the intake pipe is discharged, so that a certain degree of vacuum is formed in the pump to achieve the effect of self-suction. If there is a need to further increase the suction height, then the installation should pay attention to the suction tube as short as possible, ZMD fluoroplastic magnetic self-priming pump suction should try to avoid valves, elbows and tees. The vertical height of the discharge pipe is within 1 meter, and within 1 meter perpendicular to the outlet of the pump, no elbow is set in the middle, then the large suction height of the pump can be obtained. It is made of hard metal, which is very similar to the application of photocopying technology. The other subsystem is similar to other contactless technologies in function, but in fact its structure is very different. The surface structure of the printing drum is a layer of electromagnetic hard layer, the electromagnetic is placed on the magnetic soft material, and the magnetic strength is about between 500oerst.
