Jet Edge awarded U.S. patent for ultrahigh-pressure waterjet seal

January 16, 2013

Jet Edge Inc., St. Michael, Minn., has announced it has received a patent for a mechanism that provides metal-on-metal sealing without the use of conventional plastic seals. This technology uses two convex, curved surfaces in single-line contact with one another to seal ultrahigh-pressure (UHP) fluid at static pressures up to 130,000 PSI.

The technology has allowed the manufacturer to eliminate static seals in its XP intensifiers and Eco-Jet direct-drive pumps, cutting in half the number of seals that can fail or need to be changed.

Jet Edge manufactures complete waterjet systems, including precision, CNC waterjet gantries; waterjet pumps; accessories; and parts.
