The WFB series leak-free self-priming pump uses a leak-free V-type sealing assembly, eliminating traditional pump packing seals, gland seals, and mechanical seals, and thoroughly addressing the issues of "leakage, dripping, and spillage." It is an ideal replacement for various long-shaft submersible pumps, submersible pumps, sewage pumps, etc. The disadvantages of this pump structure are: 1. Liquid leakage along the shaft direction when the pump is stopped, making it less suitable for frequently started devices; 2. Excessive power consumption by the auxiliary impeller, resulting in low pump efficiency. The improved WFB structure includes a sealing device, which increases pump efficiency, reduces motor power, and suppresses the leakage phenomenon during pump shutdown. The sealing device does not produce friction or wear during operation, resulting in a service life more than ten times longer than similar products. It adopts the principle of a vacuum pump, ensuring stable and reliable self-priming performance, especially with the use of an "electric air control valve" that truly achieves "one-time drainage and lifetime self-priming." It features high efficiency, low vibration, low noise, flexible mobility, easy disassembly, simple installation, and does not require a fixed base, eliminating the difficulties of transporting, installing, and maintaining long-shaft submersible pumps. With superior self-control functionality, it can be used in conjunction with high-tech fields and highly automated series.

Application range:
The WFB series leak-free self-priming pump has various functions such as temperature resistance, pressure resistance, wear resistance, "one-time drainage," and "lifetime self-priming." Currently produced with materials such as PTFE, chlorinated polyether, ultra-high molecular polyethylene, polypropylene, stainless steel, cast steel, and gray iron. The WFB leak-free self-priming pump is widely applicable in industries such as electronics, power, chemical engineering, metallurgy, pharmaceuticals, food, electroplating, environmental protection, firefighting, municipal, water purification, national defense and military industry, textile dyeing, and mining selection.
Leak-free self-priming pumpStructural description:
Leak-free self-priming pump is divided into five models: Model 1 is a rectangular leak-free self-priming pump, Model 2 is a conical leak-free self-priming pump, Model 3 is an explosion-proof leak-free self-priming pump, Model 4 is an outdoor leak-free self-priming pump, and Model 5 is a trolley mobile leak-free self-priming pump. The flow rate design of the leak-free self-priming pump ranges from 0.75 to 6850 m³/h, with a head of 5m to 132m, suction inlet diameter of 16 to 800 mm, and discharge outlet diameter of 10 to 600 mm.
