Corrosion-Resistant Fluorine Pump WB2 Series Mechanical Seal - China Suppliers & Factory
Product Introduction
WB2 series is a single-face balanced mechanical seal designed for PTFE (corrosion resistant) pumps. Its core is made of polytetrafluoroethylene (PTFE) bellows, and the spring is protected by the PTFE cover, so the strong corrosion resistance is excellent. The structure is externally mounted, with arbitrary rotation direction, which can adapt to various acid, alkali and salt solutions, especially suitable for media containing particles.
Features
1
Comprehensive Corrosion Resistance
Main body corrosion resistance: the corrugated pipe, auxiliary sealing ring and other main parts adopt polytetrafluoroethylene (PTFE), which can withstand most acid, alkali, salt and other strong corrosive media.
Optional end faces: the friction pair end faces are provided with silicon carbide, tungsten carbide and other super hard corrosion-resistant materials, which can be customized according to the specific media to ensure the long-term sealing.
2
Stable and Reliable Structure
Spring protection: Multi-spring design is adopted, and the spring is completely wrapped by the PTFE cover, isolated from the medium, effectively preventing the failure caused by crystallization or particle blockage.
Easy installation: the external structure makes it easy to install, observe and replace the pump without removing the pump body, and the maintenance is simple.
3
Extensive Environmental Adaptability
It is designed to rotate in any direction without restricting the rotation direction of the pump shaft, with strong versatility.
It can adapt to media containing crystal particles (strong alkali, etc.) and is not easy to be blocked.
Frequently Asked Questions
Q What is the WB2 series mechanical seal mainly used for?
The WB2 series is a single-face balanced mechanical seal specifically designed for PTFE (corrosion resistant) pumps. It is especially suitable for handling acid, alkali, salt solutions, and media containing particles or crystal contaminants.
Q Why is PTFE used as the main material in the WB2 seal?
Polytetrafluoroethylene (PTFE) offers outstanding chemical resistance, capable of withstanding most strong acids, alkalis, and salt solutions. Its use in the bellows and auxiliary sealing rings ensures excellent and durable corrosion protection.
Q What end face materials are available for the WB2 series?
The friction pair end faces can be customized with silicon carbide or tungsten carbide materials. These are super hard, corrosion-resistant options that can be selected based on the specific media requirements to ensure long-term sealing performance.
Q How does the spring protection design benefit the WB2 seal?
A multi-spring design is adopted where each spring is completely encased in a PTFE cover, isolating it from the process medium. This prevents crystallization or particle buildup from blocking or degrading the spring, significantly extending the seal's service life.
Q Does the WB2 seal support both clockwise and counterclockwise pump rotation?
Yes. The WB2 series is designed for arbitrary rotation direction, meaning it is compatible with both clockwise and counterclockwise pump shaft rotation without any modification, offering strong versatility across different pump configurations.
Q Is the WB2 seal easy to install and maintain?
Yes. Thanks to its external mounting structure, the WB2 seal can be installed, inspected, and replaced without removing the pump body. This design makes routine maintenance straightforward and minimizes equipment downtime.
