Sealing Excellence

Cleanroom Assembly & High-Pressure Dynamic Rig

MechFlow houses advanced cleanroom facilities and dynamic test benches designed to simulate actual site operating pressures, temperatures, and speeds for hazardous hydrocarbon gas compressors and critical pumps.

API 692 Compressor Dry Gas Seals (DGS)

Dynamic testing of single, tandem, and double DGS cartridges using inert nitrogen up to 150 bar with precision primary vent leakage measurement.

Helium Light-Band Optical Flat Lapping

Diamond slurry precision lapping of silicon carbide, tungsten carbide, and carbon face rings to within 1-2 helium light bands (0.3 to 0.6 micron flatness).
