WFB type of non-sealed automatic self-priming pump is a widely used pump in the chemical industry. In this article, we will discuss the classification and features of this pump.
Classification
WFB type of non-sealed automatic self-priming pump is a single-stage, non-sealed, self-priming centrifugal pump. It can be divided into two types: WFB and WFB-1. The WFB-1 type has a backflow device and a check valve. Both types of pumps are used for conveying corrosive liquids with a viscosity of less than 100 centipoise and a temperature of -20℃ to 100℃.
Features
Non-sealed structure
The pump is non-sealed, which means it doesn't need mechanical seals. This reduces the risk of leakage and makes it more reliable.
Automatic self-priming
The pump has an automatic self-priming function, which means it can automatically suck liquid without the need for a foot valve and vacuum pump.
Wide range of applications
The pump is suitable for conveying various corrosive liquids in the chemical industry, such as acids, alkalis, oils, and other chemical liquids.
High efficiency
The pump has a high efficiency, which means it can save energy and reduce operating costs.
Corrosion resistance
The pump is made of plastic, which makes it highly resistant to corrosion.
Easy maintenance
The pump is easy to maintain because of its simple structure.
In conclusion, WFB type of non-sealed automatic self-priming pump is a highly efficient and reliable pump that is widely used in the chemical industry. Its non-sealed structure, automatic self-priming function, high efficiency, corrosion resistance, easy maintenance, and wide range of applications make it an ideal choice for many chemical plants.
The unique advantages of the new WFB type of non-sealed automatic self-priming pump
- They adopt the "multi-sided centrifugal seal for pump", eliminate the traditional pump filler sealing, disc sealing and mechanical sealing, and completely solve problems like "leakage, overflow, dripple and seepage", thus becoming the ideal options that replace a variety of submerged long shaft pumps, submerged pumps and other kinds of pumps.
- During their operation, the sealing device is subject to no friction or wear; their service life is over 10 times longer than that of peer products.
- We transplant the principle of vacuum pump onto these pumps and thus achieve a stable and reliable self-priming performance. In particular, they adopt the "electric air-regulating valve", thus truly realizing the "permanent self-priming from one drainage".
- The small vibration, low noise, flexible movement, simple and convenient disassembly, easy installation and no need for foundation bolt fixation.
- They have a superior automatic control function and can work in high-tech fields with highly automated systems.

Features
- The fluid is not delivered directly by the impeller,the fluid gains the energy from the vortex generated by the rotating impeller.
- Non-clog performance on pumping fluids with big particles.
- Intertwine free performance on pumping fluids with fibers and suspending materials.
- Non-stop performance on pumping fluids with air.
- The biggest solid in the fluid can be as big as 80% of the pump diameter,and the weight density is up to 60%.
Structure
- Horizontal,single stage cantilever structure.
- Axial suction and radial discharge,and the discharge can be rotated 90° to horizontal direction.
- Soft packing seal with high pressure shaft sealing water during operation.
- Directly driven by the motor through the couplings.
- Simple structure and easy maintenance.
