Certification standard
The aging resistance and chemical composition of rubber and sealing materials are covered by ASTM standards. A worldwide instrument for evaluating quality management systems is ISO 9001 certification. The RoHS Directive's standards for hazardous materials in vacuum pump gaskets must be met by gasket manufacturers. REACH rules guarantee that chemicals comply with relevant laws and the necessary filings, registrations, and reports. These guidelines aid in ensuring that gaskets satisfy international requirements for customer satisfaction, process control, and quality management.
Introduce
A vacuum pump gasket is a type of seal that stops liquid or gas from leaking between a vacuum pump and adjacent machinery. Usually constructed from pliable, heat-resistant, and chemical-resistant materials, it aligns with the vacuum pump's connecting section. To create a sealing barrier, the gasket is placed at the connecting surface and squeezed when tight.
Advantage
- Simple structure: The structural design of vacuum pump gaskets is relatively simple, which is easy to install and replace.
- High temperature and chemical corrosion resistance: Vacuum pump gaskets are usually made of high-strength, high-modulus materials such as FKM, which have good high temperature and chemical corrosion resistance.
- Self-lubrication: Some pump gasket materials have self-lubricating properties, which can reduce friction and extend service life.
- Good thermal conductivity: FKM gasket materials usually have good thermal conductivity, which helps to maintain stable performance in high-temperature environments.
- Low thermal expansion coefficient: FKM gaskets have a low thermal expansion coefficient and can maintain dimensional stability when the temperature changes.
