DBM is a compact face-type mechanical seal designed for reliable and safe operation under demanding conditions. Its stationary design minimizes the centrifugal effect on elastomers, making it suitable for high-speed applications. The seal supports bi-directional installation and can also be configured as a rotary mechanical seal according to specific equipment requirements.

DBM metal bellows mechanical seal is available in both cartridge and component versions. Both configurations are suitable for high-temperature, high-speed, medium- to high-viscosity and light-vacuum applications. The compact design provides reliable sealing performance across a wide range of operating conditions.

Applications

DBM mechanical seal is widely used in chemical pumps, petrochemical and refinery equipment, sewage pumps, pulp pumps, vacuum pumps, water treatment equipment, food and beverage processing equipment, and pharmaceutical machinery.
