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.

• 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
