WFB unsealed self-controlself priming pump(Common type)

1、 Overview

The WFB series unsealed self-priming pump is the first product to fill the domestic gap. This product has multiple functions such as temperature and pressure resistance, "one-time drainage", and "lifelong self-priming". At present, we produce a series of complete machines made of various materials such as 321, 304, 316, 316L, A3, PP (reinforced polypropylene), etc., with five different shapes and more than one thousand specifications. Widely applicable in industries such as electronics, power, chemical, metallurgical, pharmaceutical, food, electroplating, environmental protection, fire protection, municipal, water purification, national defense and military, textile printing and dyeing, mining and mineral processing, and civil construction, it has received high praise from users.

2、 Unique advantages
1. By adopting the "pump series multi-faceted centrifugal sealing device", the traditional water pump's packing seal, packing seal, and mechanical seal have been eliminated, completely eliminating "running, emitting, dripping, and leaking", and replacing various long shaftsSubmersible pumpThe most ideal equipment such as submersible pumps.
2. The sealing device does not rub or wear during operation, and its service life is more than 10 times longer than similar products.
3. The principle of transplanting vacuum pump has stable and reliable self-priming performance, especially with the use of an "electric air control valve", which truly achieves "one-time drainage, lifelong self-priming".
4. Low vibration, low noise, flexible movement, easy disassembly and installation, no need for foot fixation.
5. It has superior self-control function and can be used in conjunction with high-tech fields and highly automated systems.
