    WFB series non-sealing slf- control and self priming has features of  heat, corrosion and wear resistant, no leakage, "Once priming", "life-long self-suction". At present, there're five kinds, totally one thousand of specification with material 321, 304, 316, 316L, A3, PP(reinforced ployproylene). The product is widely used in the fields of exlectronic, electrical, chemical, metallurgy, medicine, food, electroplaing, environmental protection, fire fighting, municipal services, water clean, national defense industry, textile printing and dyeing, mining mineral processing, civil construction and other industries. Our company enjoyed a good reputation in the market.


Unique Advantages

    1.We applied the "multi-faceted type centrifugal sealing device", which get rid of traditional filling seals, packing seals, mechanical seak, thoroughtly overcome "running, emitting, dripping and leakage," and it is an idal substitute to original long shaft pump, submersible pump and sewage pump.

    2.The service life of sealing device is 10 times of similar products, without wear and abrasive in opration.

    3.Transplant working principle of vacuum pump, stable and reliable self- suction performance, in paticular, the adoption of "electric air control valve", achieves "once-priming, life-long self- suction".

    4.Small vibration, low noise, flexible move, simple diassembly, easy installation, no need to fix anchor.

    5.Blessed with excellent self-ontrol, can match to hi-tec and hi-auto systems.

Functions for different types 

    The rectangular  type and cone type products can provide the users with the different installaiton type; explosion-proof type is applicable to flammable and explosive environment; outdoor type can effectively prevent rain, fog, moisture and humid outdoors by virtue of safe thee-dimensional  hood; mobile cart can move the pump to ny working place you need.
