overview
The WFB series unsealed self-priming pump 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.

advantage
1. Our company adopts the "pump series multi-faceted centrifugal sealing device", which eliminates the traditional filling seal, packing seal, and mechanical seal of water pumps, and completely eliminates the "running, emitting, dripping, and leaking". It is an ideal equipment to replace various long shaft submersible pumps, submersible pumps, and so on.

2The sealing device does not rub or wear during operation, and has a longer service life 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.

selection method
(1) The meanings of 1-5 in the "Category Code" column of the performance parameter table are: Type 1 is rectangular, Type 2 is conical, Type 3 is explosion-proof, Type 4 is outdoor, and Type 5 is cart mobile. The four letters G, PP, and BXG in the "Material Symbol" column represent three materials: steel, reinforced polypropylene, and stainless steel.

(2)Example of Model Meaning:

50WFB-AD1

50——Pump inlet diameter (mm)

WFB——Unscented self controlled self-priming pump

AD1——Performance classification

(3)Complete model writing method. Assuming that the requirements for the water pump are: the shape is a trolley mobile type, the material is reinforced polypropylene, the suction diameter is 50mm, and the performance classification is AD1. The complete model of this water pump is "5PP50WFB-AD1"

Assuming the shape of the water pump is rectangular explosion-proof, other requirements are the same as above. The complete model of this water pump should be written as "1.3PP50WFB-AD1"

Assuming the design of the water pump is conical explosion-proof, with other requirements as above, the complete model of this water pump should be written as "2.4PP50WFB-AD1"
