NUTECH D7 ASSEMBLY SEAL
Features and Benefits
Balanced - The Exact-A-Gen is internally balanced, requiring no special sleeves or costly machining of shouldered shafts.
No Fretting - The Exact-A-Gen seal will not fret sleeves or shafts. The 'O' ring on the shaft is static and should any fretting occur from the dynamic 'O' ring, it will be to the carbon holder, the least expensive part of the seal.
Easy Installation - One installation dimension is common to all Exact-A-Gen seals, regardless of shaft size.
No Exchange - We supply an 'infield' repair kit for a fraction of the original cost. You don't have to send back seals for repair or exchange - this way it costs you less.
Fits All AVS/ANSI Pumps - Replaces most seals or packing without pump or gland modification.
Isolated Springs - Springs are out of the fluid being pumped, isolated from clogging particles suspended in the product.
Non-Clog - Exact-A-Gen has eliminated unnecessary tight clearances leaving the seal open to continual washing by the product up to the 'O' ring.
Drive Collar - Exact-A-Gen seal has a large cross section drive collar to eliminate distortion and static 'O' ring leakage.
