7/8" Pump Parts
Pump parts compatible with the 7/8" version of Jet Edge waterjet pumps: backup disk kits, backup rings and bearings, plus 10" water filter cartridges.
The 7/8" and 1" versions look alike but their seal-side parts are not interchangeable, so confirm the size on the pump before ordering. When the high-pressure seal is changed, renewing the backup ring and disk at the same time gives the new seal a proper support and a normal service life.
Parts in this section are compatible replacements. Third-party brands and references identify the equipment the part fits and do not imply it is an original spare from that manufacturer.
