WFB Series seal-controlled pump leak-free seal assembly V, get rid of the traditional pump packing, packing seals, mechanical seals, completely subdued the "run, run, drip, leak," is to replace the original variety the best equipment pumps, submersible pumps, submersible sewage pumps and other fluid under the long axis. The structure of the pump drawbacks: First, stop the liquid leak out along the axis, for frequent starting equipment is not suitable for the occasion; two, deputy impeller consume too much power, low pump efficiency. WFB improved structure for sealing means, first, to improve the efficiency of the pump, the second is to reduce motor power, the third is to suppress the pump stop leakage. Sealing device during exercise without friction, no wear 40WFB-A2 sealless pump-controlled, long service life than similar products more than 10 times. Transplantation vacuum principle, self-priming and reliable performance, especially the use of "electric air control valve" so that "once draining, life-long self-absorption." High efficiency, small vibration, low noise, mobile and flexible, easy to disassemble, easy to install, no foot fixed, eliminating the long axis of the liquid pumps transport, installation, maintenance and other difficulties. Has excellent self-control function, can be used with high-tech fields and highly automated system supporting the use of WFB Series seal-controlled pump - Four Features 1. The pump seal-controlled pump 40WFB-A3 reliable, leak-free seals, specifically by the dynamic seal and the secondary seal components. Alternative to the traditional pump packing seal, mechanical seal 32WFB-A controlled pump, completely solve the traditional seal '' run, run, drip, leak '' and other issues. Under the original alternative to the long axis of liquid pumps, submersible pumps, submersible sewage pumps and other best products. Process 2. The pump is not running seal friction, no wear, longer life than traditional products than 1 O-fold. Self-priming pump principle transplant reliable performance, especially the use of "electric air control valve" truly a first drainage permanent self-priming, the pump unit vibration, low noise, mobile and flexible, easy disassembly. Has excellent self-control function, and associated control systems supporting achieve a high degree of automation. 16WFB controlled pump, controlled pump, WFB no sealed-controlled pump is provided by Anguo Shi Yuan Pumps Limited.
