Liquiflo’s ENDURA^® Pumps are Group I & Group II ANSI-Dimensional Magnetically-Coupled Seal-less Centrifugal Pumps. These pumps were designed to meet the demanding needs of the chemical processing industry but will also handle many pumping applications, including those which require dry-running, pumping solids as well as high-temperature demands.

ENDURA® AB - Air Barrier
Liquiflo’s ENDURA^® AB-Series is our Patented Air-Barrier Centrifugal Pump. This innovative revolutionary design was the recipient of the 1995 Vaaler Award. The ENDURA^® AB can run dry indefinitely and handles solids - something no other pump in the industry can do.

The AB, (air-barrier) combines the best features of a standard sealed pump with that of a mag-drive pump, while eliminating the drawbacks commonly associated with these designs. This patented design makes the ENDURA^® AB unlike any other pump in the industry.

How it works:
A gas seal isolates the process fluid from the bearings within a mag-drive pump. The benefit of this design is that the ENDURA^® AB does not rely on the pumpage for lubrication. This allows the use of standard, greased-for-life ball bearings instead of the common sleeve bearings found in all other magnetically driven pumps.

Other Great Features:
  • Can run dry indefinitely
  • Lowest L3/D4 ratio of any pump - 9.3
  • Solids handling up to 40%
  • Close-coupled or power-frame
  • ANSI dimensional for easy change-out
  • Inherent secondary containment
  • No seals to leak
