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.
1, our factory adopt "polyhedral centrifugal pump with a serial type sealing device" abolish the traditional pump packing seal, packing seal, mechanical seal, completely uniform "run, run, drip, leak," is to replace the original all kinds of long shaft submerged pump, submersible pump, submersible sewage pump, the most ideal equipment.
2, sealing device during the operation of no friction, no wear, long service life than similar products more than 10 times
3, transplant principle of vacuum pump, self-priming is stable and reliable, especially the electric air control valve, truly realized "a drainage, life-long self-priming.
4, small vibration, low noise, mobile flexible disassembly is simple, easy to install, no need to anchor fixation.
5, with excellent self-control, can be used with high-tech fields and highly automated systems
Different Formative Purposes
rectangular, the installation of the cone type to provide different forms of choice, explosion-proof type suitable for flammable, explosive environment, outdoor using Ann check solid door cover, under the condition of operation in the open, effective waterproof, prevent mist, moisture, well protected against dampness, cart moving type pump can be went on to what you need on any location.
