1、 Overview

The WFB series unsealed self-priming pump has multiple functions such as temperature and pressure resistance, "one-time drainage", and "lifelong self-priming". Currently producing 321, 304 A series of complete machines made of various materials such as 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 the "running, emitting, dripping, and leaking" issues. It is an ideal equipment to replace various long shaft submersible pumps, submersible pumps, and other types of equipment.
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.

3、 Selection method
50WFB-AD1
50- Pump inlet diameter (mm)
WFB - Non sealed Self controlled Self priming Pump
AD1- Performance Classification
The flange of the water pump is manufactured according to the national standards of the People's Republic of China. Standard code GB9115.2-88; GB9115.3-88。 The flange pressure of non-metallic material water pump is 0.6MPa; The flange pressure of the metal material water pump is 1.0MPa. Our company's water pumps are equipped with a counter flange at the inlet and outlet when they leave the factory.
