Product overview
type wfb without sealing automatic self-priming pump (hereinafter referred to as: wfb self-priming pump), is new and sealed with the function of automatic self-priming pump products. Using "cascade" polyhedral centrifugal sealing device, no "run, drip, take, drop". Due to the operation without seal friction, no wear, so several times compared with similar products to extend the service life. Wfb self-priming pump with heat resistance, pressure, wear-resisting "a drainage, life-long self-priming" and other functions, reliable self-priming performance, especially the "electric air control valve" has the characteristics such as reliable running, convenient disassembly and would like to install. Respectively, reinforced polypropylene, cast steel, stainless steel and other materials, can be respectively applied to various occasions, also designed the multiple forms, according to the needs of user of rectangle, conical, can provide you with different type of installation options. Explosion-proof type, outdoor, can be used in inflammable and explosive, rain, damp places. Cart type mobile more water pump can be easily sent to any work you need.
