Flowserve Type 21 Mechanical Seals are a type of mechanical seal designed and manufactured by Flowserve Corporation. These seals are used in various industrial applications to prevent leakage of fluids or gases from pumps, compressors, and other rotating equipment.The Type 21 mechanical seal is a single-spring, unbalanced design that features a rotating face and a stationary face. The rotating face is connected to the shaft of the equipment, while the stationary face is mounted in the seal housing. When the equipment is in operation, the rotating face and stationary face come into contact with each other, creating a seal that prevents leakage.Flowserve Type 21 mechanical seals are known for their reliability and durability. They are designed to handle a wide range of operating conditions, including high pressures and temperatures.
