A Type 21 Pump Seal is a standard mechanical seal used in a variety of centrifugal pump applications. It is a popular choice for applications in the chemical, pharmaceutical, and food and beverage industries, among others.
The Type 21 seal consists of two main components: a rotating part, which is attached to the pump shaft, and a stationary part, which is mounted in the pump housing. The two parts are separated by a thin film of lubricant, which prevents leakage. The seal faces are typically made of carbon and ceramic materials, which are resistant to wear and corrosion.
The Type 21 seal is designed to handle a wide range of temperatures and pressures, making it suitable for a variety of applications. It is also relatively easy to install and maintain, making it a cost-effective choice for many pump systems.
Overall, the Type 21 standard pump seal is a reliable and widely-used mechanical seal that provides effective sealing performance in a variety of pump applications.
