Bellows Double Seal
(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.
Features:
Inboard bellows unit ideally situated to replace sliding elastomer of conventional pusher type seal
Integral bi-directional flow inducer
Fits on pumps with thin radial cross sectional spaces
50% more bellows than industry standard reduces stress on each convolution of bellows stack
Modular design enables use on multiple applications, simplicity of purchase and fast delivery
