WFB Type No Sealed Self-priming Pump

WFB type no sealed self-priming pump with no leakage V-type sealing assembly，Eliminate the traditional pump packing seal, packing seal, mechanical seal，Completely subdued“leak, run, drop, drain”，is ideal equipment to replace the old long axis liquid pump, submersible pump, submersible sewage pump,etc.

WFB the improved structure is a sealed device，first to improve pump efficiency,Second to lower the motor power，Third to inhibit the leakage of pump downtime.During the movement of the sealing device does not friction, no wear, the service life of more than 10 times longer than similar products.Transplant vacuum pump principle, self-priming performance is stable and reliable，In particular, the use of "electric air control valve" truly "a drainage, lifelong self-absorption".High efficiency, low vibration, low noise, flexible mobile, easy to disassemble, easy to install, no fixed feet, eliminating the need for long axis liquid pump transport, installation, maintenance and other difficulties.With excellent self-control function,supporting the use of high-tech field and a high degree of automation system .

Defective of this pump structure：The stop liquid leaks out of the shaft，For frequent occasions to start the device is not suitable；The impeller consumes too much power and the pump is inefficient.

Application range：
WFB no sealed self-priming pump with features of anti-high temperature,anti-pressure,anti-wear、"A drainage "," life-long self-absorption. ".Now there are materials of Lined PTFE, chlorinated polyether, ultra-high molecular weight polyethylene, polypropylene, stainless steel, cast steel, pig iron, etc.WFB type no sealed self-control and self-priming pump is widely used in electronics, electric power, chemical industry, metallurgy, medicine, food, electroplating, environmental protection, fire, municipal, water purification, national defense industry, textile printing and dyeing, mining and other industries.

Structure description:
There are 5 types of no sealed self-control and self-priming pump：1Type for the rectangular non-sealed self-priming pump，2 Type for the cone typeof no seal self-control self-priming pump，3 type for anti-explosive no seal self-control self-priming pump，4 type for outdoor type seal self-control self-priming pump，5 type for cart moving no seal self-control self-priming pump.
Performance range,Capacity range:0.75—6850m3/h、Head range:5m—132m、Inlet diam. Range:16—800 mm、Outlet diam. Range:10—600 mm.
