Flexo presses get better seal

Oct. 6, 2005
Type 2106 Elastomer Bellows Seal uses full convolution elastomer bellows and interlocking drive bands to provide positive drive in sealing pumps that go into flexographic printers.

The bellows seal, from John Crane Inc., Morton Grove, Ill. (johncrane.com), comes with standard carbon versus ceramic faces or a new grade of silicon carbide that reportedly provides excellent wear resistance, dry run tolerance, and facilitates a wider spectrum of operation. Type 2106 seal components meet UL 1081 requirements. In addition, these components meet FDA requirements as well as those of the National Sanitary Foundation (NSF) and the Canadian Standard Association Standard CAN/CSA-22.2 No. 108-M89 Liquid Pumps. The pump components also serve in small centrifugal water pumps, deep and shallow well jet pumps, and swimming pool pumps, as well as in wastewater pumps.
