we can supply various mechanical seals, such as metal bellows seal, cryogenic metal bellows seal, CrO coated stainless steel ring, wave spring and rubber ring, mechanical seal supporting system, fluid reservoir, hand refill pump, heat exchanger, cyclone dust separator, dry gas face, cartridge mechanical seal and long sleeve metal bellows seal, etc..

Low temperature bellows sealing is a sealing technology used in extreme low temperature environments, which ensures the safety of pumped fluids while providing long-term reliability. When designing pumps for transporting low-temperature fluids, special designs are often used, such as vertical multi-stage double shell pumps according to the American Petroleum Institute (API) 610 standard. These pumps have a heating chamber called a cofferdam that can thermally isolate the shaft seal from the cold pumped fluid, allowing for the use of traditional sealing techniques
