Cutting out grinding with mechanical seal

John Crane has designed a mechanical seal which may do away with the need for packing seals on pumps and rotating shafts.

Jim Gilbert, global product development manager, says that during production of the 4610 cartridge seal, `by eliminating grinding it lends itself to high volume production. We tried to design out the machining process, even chuck changes.’

It can be used where ANSI/DIN/API design seals will not fit, including water based and close coupled or vertical water pumps, and can be installed without the need for seal setting, equipment modification or additional components.
