Manufactured in China, this innovative product features a core constructed from polytetrafluoroethylene (PTFE) bellows, ensuring exceptional resistance to corrosion. The protective PTFE cover safeguards the spring, enhancing durability. This externally mounted structure allows for arbitrary rotation direction and is highly adaptable to various acid, alkali, and salt solutions. With its robust design, the WB2 series is particularly suitable for media containing particles, making it a reliable choice for industrial applications. Trust the leading suppliers and factory in the industry to deliver the performance you need with the WB2 series mechanical seal
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
Q1: What is the WB2 series mechanical seal primarily designed for?
The WB2 series is specifically designed for PTFE (corrosion-resistant) pumps. It features a PTFE bellows core and spring protection, making it ideal for handling highly corrosive media such as acids, alkalis, and salt solutions.
Q2: What materials are used for the sealing end faces of the WB2?
The friction pair end faces are available in silicon carbide (SiC) and tungsten carbide (WC), both of which are super-hard corrosion-resistant materials. The material can be customized to match specific media requirements to ensure long-term sealing performance.
Q3: Can the WB2 seal handle media containing solid particles?
Yes. The WB2 is especially suitable for media containing crystal particles, such as strong alkali solutions. The PTFE-encased multi-spring design effectively prevents blockage from crystallization or particle accumulation.
Q4: Does the WB2 mechanical seal restrict the pump shaft rotation direction?
No. The WB2 is engineered to support rotation in any direction, so there is no restriction on the pump shaft's rotation direction. This makes it highly versatile and compatible with a wide range of pump configurations.
Q5: How easy is it to install or replace the WB2 mechanical seal?
The WB2 features an external mounting structure, which means installation, inspection, and replacement can be carried out without removing the pump body. This significantly simplifies maintenance and reduces downtime.
Q6: Why is the spring in the WB2 seal more durable than conventional designs?
The WB2 uses a multi-spring design where each spring is completely enclosed within a PTFE cover. This isolates the springs from the process media, preventing corrosion, crystallization buildup, and particle-induced blockage that commonly cause spring failure in standard mechanical seals.
