Magnetic drive centrifugal process pump
max. 375 gpm, max. 275 psi | ENDURA® AB series Liquiflo

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.

Great Features of the Endura Air-Barrier® Pump:

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
Greased-for-life antifriction ball bearings
Gas seal prevents process fluid from contacting bearings
Inherent secondary containment
Magnetically driven - NdFeB or SmCo high-strength magnetic couplings
Transformation Toughened Zirconia (TTZ) ceramic containment can eliminates eddy current losses
