Bellows Double Tandem Pumping Double Seal – BDTP, C&B Equipment, INC.

Bellows Double Seal

The BDTP™ (Bellows Double Tandem Pumping) is a highly-innovative hybrid design, modular to the BDFI™. The seal's directed barrier fluid flow path achieves optimum heat removal at both sets of seal faces. The inboard bellows unit is ideally suited to replace the semi-dynamic sliding elastomer of a conventional pusher type seal which allows it to be more readily applied to thermal applications.
