our dry gas seals and mechanical seals.

Dry Gas Seals

Dry gas seal (DGS), as a typical kind of noncontacting mechanical seal, meets satisfactorily the requirements of low leakage rate, wear-free operation, and low power consumption for industrial compressors, pumps, fans and other turbo-machines .

Mechanical Seals

Mechanical seals are indispensable for sealing rotating shafts. DERUI mechanical seals includes standard cartridge, pusher, metal bellow, mixer, compressor, slurry, etc.

Carbon Floating Ring Seals

Carbon floating ring seals are used, if the application has a circumferential speed above 40 m/s, normally for turbine and compressor applications.It offers exceptional maintainability.

Single Seals

Single seal is a type of mechanical seal which consists of one primary seal and it seals from process to atmosphere.There is always some leakage either to atmosphere or into process depending on the process pressure.

Dual Seals

Dual (or double) mechanical seals are designed to ensure maximum sealing safety. These seals virtually eliminate leakage of the fluid or gas being handled in pumps or mixers.

Tandem Seals

DERUI’s DG82 series(tandem design) designed for centrifugal compressor. DG820, DG821,DG822 are optimized for low-pressure compressor applications. DG823 for high-pressure compressor applications.

Seal Support System

Seal support system providing lubrication, controlling pressure and temperature, flushing contaminants, and containing leaks, seal support systems ensure reliable, long-lasting seal performance across a wide range of industrial applications.
