Sealed self-priming pump structure advantages and disadvantages

WFB series of non-sealed self-priming pump with leak-free V-type seal assembly, leather in addition to the traditional packing seal, packing seal, mechanical seal, completely uniformed "run, run, drip, drain" , Is to replace the original variety of long axis submerged pump, submersible pumps, submersible sewage pumps and other ideal equipment. But there are also shortcomings, now Xiaobian say no seal self-priming pump structure advantages and disadvantages. Sealless self-priming pump First, the structure of self-priming pump without seal Advantages WFB improved structure is a sealed device, one is to improve the pump efficiency, the second is to reduce the motor power, the third is to inhibit the pump downtime leakage. Sealing device during the movement is not friction, no wear and tear, the service life of more than 10 times longer than similar products. Transplantation of vacuum pump principle, self-priming performance is stable and reliable, especially the use of "electric air control valve" truly "a drainage, lifelong self-absorption." High efficiency, low vibration, low noise, flexible movement, easy disassembly, easy installation, no need for foot fixing, eliminating the need for long axis liquid pump transportation, installation, maintenance and other difficulties. Has superior self-control function, with high-tech fields and a series of highly automated systems supporting the use of. Second, the structure of non-sealed self-priming pump Disadvantages of liquid down the leakage along the axial direction, for frequent starting equipment is not suitable for occasions; Vice impeller power consumption is too large, the pump is inefficient.
