WFB series non-sealed self-control self-priming pump adopts a non-leakage V-shaped seal assembly, which eliminates the packing seal, packing seal, and mechanical seal of traditional water pumps, and overcomes the phenomenon of "running, emitting, dripping, and leaking".

    The improved structure of WFB has a sealing device. One is to improve the efficiency of the water pump, the other is to reduce the power of the motor, and the third is to suppress the leakage of the water pump when it stops. During the movement, the sealing device has no friction and no wear, and the service life is more than 10 times longer than similar products. The principle of transplanting vacuum pump, self-priming performance is stable and reliable. High efficiency, low vibration, low noise, flexible movement, easy disassembly, easy installation, no need for foot fixation, eliminating the difficulty of long-axis sump pump transportation, installation, and maintenance. With the automatic control function, it can be used in combination with high-tech fields and highly automated series.

    Disadvantages of the structure of the pump: the stop liquid leaks out along the axis, which is not suitable for the occasions of frequently starting equipment; the auxiliary impeller consumes too much power and the pump efficiency is low.

 

Use range:

 

The WFB series non-sealed self-control self-priming pump has many functions such as temperature resistance, pressure resistance, wear resistance, and so on. At present, it produces a variety of materials such as tetrafluoroethylene, chlorinated polyether, ultra-high molecular polyethylene, polypropylene, stainless steel, cast steel, pig iron and so on. WFB type non-sealed self-control self-priming pump is widely used in industries such as electronics, electric power, chemical industry, metallurgy, medicine, food, electroplating, environmental protection, fire protection, municipal administration, water purification, textile printing and dyeing, mining and mineral processing.

 

Structure description:

 

There are five types of non-sealed self-control self-priming pumps: Type 1 is a rectangular non-sealed self-control self-priming pump, Type 2 is a cone-type non-sealed self-control self-priming pump, Type 3 is an explosion-proof type non-sealed self-control self-priming pump, 4 Type is outdoor type unsealed self-control self-priming pump, type 5 is trolley mobile type unsealed self-control self-priming pump. The flow design of the unsealed self-control self-priming pump is from 0.75-6850m3/h, the head is 5m-132m, and the suction caliber is 16-800. mm, the liquid outlet diameter is 10-600 mm.
