WFB type no seal self priming pump, absorbs the domestic and foreign related products in the advanced experience of the foundation. Improved and innovative new product, is the traditional domestic products of the same products replace. The product has good resistance, stress and grinding, "for the first time, permanent drainage self-priming", etc. Products are cast iron, cast steel, stainless steel, reinforced polypropylene such as qualitative, five different modelling more than kinds of specifications.

Characterstics
1, the sealing is reliable. This pump USES no leak sealing devices, by secret sealing and with power of auxiliary seal.

When running, no wear, the service life is a traditional product 10 times above; 3, power sealing device, lower cost 10 years for the operation cost of packing seal of 50%, for 70% of mechanical seal; 4, self-priming performance is stable and reliable, and especially the "electric air control valves", to achieve a truly "first drainage, permanent self-priming"

Application
Widely used in the electronics, electric power, chemical industry, metallurgy, medicine, food, fire control, environmental protection, electroplating, water purification, the municipal administration, the national defense, textile, mining, construction and other industries.
