Prevent compressor leaks with this rod-sealing system
The XperSEAL rod-sealing system (photo) for compressors uses pressurized oil to keep the gas in place, ensuring leak-free sealing for the lifetime of the compressor, according to the company. This system can be retrofitted easily to existing compressors, and uses no more oil than conventional lubricated packing. A conventional compressor-packing case contains a stack of sealing elements surrounding the piston rod. With XperSEAL, a volume of pressurized oil replaces some of these elements. Because the oil conforms exactly to the surface of the rod, gas cannot leak out as long as the oil is at a higher pressure than the gas. Hall 8.0, Stand D28 — Hoerbiger Holding AG, Zug, Switzerland
