Wfb Self-Control Self-Priming Pump

WFB series of seal-less self-control self-priming pump adopts no-leakage V-type seal assembly, eliminating the traditional pump packing seal, packing seal, mechanical seal, completely subdued the running, bubbling, dripping, leakingâ??, is to replace the original variety of long-shaft submerged pumps, submersible pumps, submersible pumps, etc. Ideal equipment. Disadvantages of the structure of the pump: First, downtime liquid leakage along the direction of the shaft outward, for frequent starting equipment is not very suitable for the occasion; Second, the power consumed by the secondary impeller is too large, the pump efficiency is low.WFB improved structure for the sealing device, one is to improve the efficiency of the pump, the second is to reduce the power of the motor, the third is to inhibit the leakage of the pump shutdown phenomenon. Sealing device in the movement process without friction, no wear and tear, the service life is more than 10 times longer than similar products. Transplantation of the vacuum pump principle, self-absorption performance is stable and reliable, in particular, the use of â??electric air control valveâ?? truly realised â??a diversion, life-long self-absorptionâ??. High efficiency, low vibration, low noise, flexible movement, easy disassembly, easy to install, no need for foot fixing, eliminating the difficulties of transporting, installing and maintaining the long-shaft submerged pump. With superior self-control function, it can be used with high-tech fields and highly automated series.
