Disadvantages of the pump with this structure:

First, the shutdown liquid leaks out along the axial direction, which is not suitable for occasions where equipment is started frequently.
Second, the power consumed by the auxiliary impeller is too large and the pump efficiency is low. The improved structure of WFB has a sealing device, one is to improve the efficiency of the pump, and the other is to reduce the power of the motor
The third is to suppress the leakage of the pump when it is shut down. During the movement, the sealing device has no friction and no wear, and its service life is more than 10 times longer than that of similar products.

The principle of the transplanted vacuum pump, the self-priming performance is stable and reliable, especially the "electric air control valve" is used to truly realize "one-time drainage, life-long self-priming". High efficiency, low vibration, low noise, flexible movement, easy disassembly, easy installation, no need for foot fixation, eliminating the difficulty of long-axis submerged pump transportation, installation, and maintenance. With superior automatic control function, it can be used with high-tech fields and highly automated series systems.
