Centrifugal pumps play a crucial role in providing steady, pulse-free flows at flow rates surpassing those typically attainable with positive displacement pumps. Liquiflo offers two distinct families of centrifugal pumps designed to cater to a diverse array of chemical applications: The Centry® Series and the Endura® Series.

The AB (air-barrier) integrates the characteristics of a traditional sealed pump and a mag-drive pump, eliminating the typical drawbacks associated with these configurations. The patented design sets the ENDURA® AB apart from any other pump in the industry.

In a mag-drive pump, a gas seal separates the process fluid from the bearings. The advantage of this design lies in the fact that the ENDURA® AB doesn’t depend on the pumped fluid for lubrication. Consequently, it can utilize standard ball bearings, lubricated for life, in contrast to the commonly used sleeve bearings in other magnetically driven pumps.
