Solutions For You Industries


Oil and Gas

Cartridge seals, metal bellows seals, and dry gas seals are often used in this industry due to the high pressure and temperature conditions. Specifically, dual cartridge seals are used for handling volatile, hazardous, and corrosive fluids.

Due to the corrosive and potentially hazardous nature of the fluids handled, dual cartridge seals, PTFE (Teflon) seals, and bellows seals are typically used. The materials used for these seals are usually highly corrosion-resistant.

Sanitary mechanical seals, often made of materials compatible with clean-in-place (CIP) and sterilize-in-place (SIP) processes, are used. These seals are designed to meet stringent hygiene standards and regulations.


Food and Beverage

Like the pharmaceutical industry, sanitary mechanical seals are also widely used in food and beverage processing. These seals need to be food-grade, meaning they must resist the buildup of product and bacteria, and be able to withstand regular cleaning and sterilization.

Power Generation

High-temperature metal bellows seals, split seals and cartridge seals are typically used in these applications due to the high pressure and temperature conditions.
