WFB vertical self-priming pump

The WFB series unsealed self-priming pump has multiple functions such as temperature resistance, pressure resistance, wear resistance, "one-time drainage", and "lifelong self-priming". At present, we produce various materials such as PTFE lining, chlorinated polyether, ultra-high molecular weight polyethylene, polypropylene, stainless steel, cast steel, pig iron, etc. Widely applicable to industries such as electronics, power, chemical, metallurgical, pharmaceutical, food, electroplating, environmental protection, fire protection, municipal, water purification, national defense and military industry, textile printing and dyeing, mining and mineral processing, etc.

2、 Characteristics

The pump adopts a leak free V-shaped sealing assembly, which eliminates the traditional water pump's packing seal, packing seal, and mechanical seal, completely eliminating the "running, emitting, dripping, and leaking" issues. It is an ideal equipment to replace various long shaft submersible pumps, submersible pumps, submersible sewage pumps, etc. Disadvantages of this pump structure: Firstly, the shutdown liquid leaks outward along the axis direction, which is not suitable for situations where equipment is frequently started; 2、 The power consumption of the secondary impeller is too high, and the efficiency of the water pump is low. The WFB improved structure has a sealing device, which improves the efficiency of the water pump, reduces the power of the motor, and suppresses the phenomenon of water pump shutdown leakage.
The sealing device does not rub or wear during the movement, and its service life is more than 10 times longer than similar products.
The principle and self-priming performance of the transplanted vacuum pump are stable and reliable, especially with the use of an "electric air control valve" that truly achieves "one-time drainage, lifelong self-priming".
★ High efficiency, low vibration, low noise, flexible movement, easy disassembly, easy installation, no need for foot fixation, eliminating difficulties such as transportation, installation, and maintenance of long axis submersible pumps.
★ It has superior self-control function and can be used in conjunction with high-tech fields and highly automated series.
