WFB series sealing automatic self-priming pump, fill the blank of the China's first product, the product has heat resistance, compression, wear-resisting, "a drainage", "life-long self-priming" and other functions. At present the production of stainless steel, reinforced polypropylene, a variety of materials such as cast steel, cast iron series machine, five different modelling, a total of more than five thousand kinds of specifications. In electronics, electric power, chemical industry, metallurgy, medicine, food, electroplating, environmental protection, fire protection, national defense, textile printing and dyeing, mining, ore dressing, widely used in civil construction and other industries. A "device" sealed polyhedral serial type centrifugal pumps, abolish the traditional pump packing seal, mechanical seal, completely uniform "run, run, drip, leak," is to replace the original variety of long shaft submerged pump, submersible pump, submersible sewage pump, etc. The most ideal equipment. Sealing device during the operation of no friction, no wear and tear. A longer service life more than 10 times.

Principle of vacuum pump, self-priming performance is stable and reliable, especially the "electric air control valve. Truly achieve the "drainage, life-long self-priming" at a time. Low vibration, low noise, mobile and flexible, easy disassembly, easy to install, no need to anchor fixation. With the superior self-control. Can be used with high-tech and highly automated systems.

Different modelling USES features: rectangular, cone type provides you with different type of installation options; Explosion-proof type is applicable to flammable, explosive environment; Outdoor using safe solid door cover, under the condition of operation in the open, effective waterproof, prevent mist, moisture, moisture proof; Cart on mobile type pump can be in any job you need on the homework.
