XWFB leak free self controlled self-priming pump

I. Overview
The WFB series unsealed self-priming pump is the first product to fill the gap in foreign markets. This product has multiple functions such as temperature resistance, pressure resistance, wear resistance, "one-time drainage", and "lifelong self-priming". At present, we produce a series of complete machines made of various materials such as stainless steel, reinforced polypropylene, cast steel, and cast iron. There are over a thousand specifications in five different styles. 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.
Unique advantages:
1. Our factory adopts the "pump series multi-faceted centrifugal sealing device", which eliminates the traditional filling seal, packing seal, and mechanical seal of water pumps, completely eliminating "running, emitting, dripping, and leaking", and is the most ideal equipment to replace various long axis submersible pumps, submersible pumps, submersible sewage pumps, etc.
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, easy installation, and 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.
The usage characteristics of different shapes:
Rectangular and conical shapes provide you with different installation options; Explosion proof type suitable for flammable and explosive environments; Outdoor type, with the help of a safe three-dimensional household cover, effectively prevents rain, fog, moisture, and dampness during outdoor operations; The trolley mobile type can move the water pump to any workstation you need for operation.
2、 Explanation on the power of the supporting motor
In order to reasonably match the motor, we draw on the advanced experience of developed countries and divide the water pump into A, B, and C working condition adaptation levels. The motor power matched in this manual is based on the A-level level. If you use it in Class B and C working conditions, you can reduce the power of the supporting motor according to the specific situation.
The A-level operating conditions are: continuous operation, and all three performance indicators of suction, flow, and head must meet the standards specified by the selected model;
The B-level operating conditions are: continuous operation, with only two of the three performance criteria meeting the standards;

The C-level operating conditions are: interval operation, and only one of the three performance criteria needs to be met.
