WFB Self-Controlled Self-Priming Pump

WFB Self-Controlled Self-Priming Pump

The WFB seal-less self-controlled self-priming pump has superior self-control and pairs with high-tech and highly automated systems. Using a leak-free V-type seal assembly, it eliminates packing, gland and mechanical seals of traditional pumps, thoroughly curing leakage, and is the ideal replacement for long-shaft submerged, submersible and sewage pumps.

Features of the WFB seal-less self-controlled self-priming pump:

A. The improved WFB has a sealing device that raises pump efficiency and lowers motor power while suppressing stop-leakage. The seal does not rub or wear in operation, giving over 10× the life of comparable products.

B. The WFB borrows vacuum-pump principles for stable, reliable self-priming; with an electric air-control valve it truly achieves "prime once, self-prime forever".

C. High efficiency, low noise, low vibration, easy installation, simple disassembly, flexible movement, no foundation fixing – avoiding the transport, installation and maintenance difficulties of long-shaft submerged pumps; ideal for clean factories.
