• Lip Seal Integration: Often combined with a PTFE lip seal for auxiliary protection against external contaminants.
• Robust Geometry: Maintains the simple, rugged Type 6 architecture but with materials capable of handling modern synthetic lubricants.
Key Features
• PTFE Upgrade: A specialized version of the Type 6 seal featuring PTFE sealing elements instead of standard rubber.
• Chemical & Oil Resistance: PTFE provides universal resistance to synthetic oils, hydraulic fluids, and aggressive additives that swell rubber seals.
• Low Friction: PTFE's low coefficient of friction reduces power consumption and heat generation at the seal interface.

Workshop
This workshop is equipped with professional processing equipment and integrated with standardized material warehousing management, enabling a one-stop production process from precision machining to finished product delivery. It ensures part machining accuracy and production efficiency, meeting various high-specification manufacturing requirements.
Product Research, Development and Testing
Our Product R&D and Testing focuses on optimizing seal performance through advanced simulation and material analysis. All seals undergo rigorous trials, including thermal cycling and pressure tests, to ensure durability, minimal leakage, and long service life in demanding industrial environments.
Industry Solutions
Case Study
Hydraulic Power Unit: A hydraulic pump seal failed repeatedly due to incompatibility with a new fire-resistant hydraulic fluid. We supplied this Type 6 PTFE Seal. The PTFE withstood the new fluid's chemistry perfectly, eliminating leaks.
Testimonials
Simple, cheap, and works in synthetic oil. A great upgrade for our gearboxes.

FAQs about Metal Bellows Seals for High Temperature Pumps
Q: Is this a mechanical seal or an oil seal (lip seal)?
A: This is a mechanical seal (face seal) designed for oil applications. It is not a radial lip seal. It uses PTFE components for the secondary sealing path.
Our company is specialized in the production of sealing materials, mechanical seals , cartridge seals.
