ARO's EXP motor technology for diaphragm pumps combats three confounding pump motor issues: freezing, stalling, and poor energy efficiency.



Featured in the June 2007 issue of Pumps & Systems, the Expert Series (EXP) Diaphragm Pump Technology is a solution for "percussion maintenance". Named for a technique commonly used on failing pumps, "percussion maintenance" - where a technician beats on the pump's stalled motor with a hammer or rubber mallet - often indicates motor deficiencies in his diaphragm pump. Though it is impossible for the maintenance department to predict when a pump will stall, such maintenance techniques are often the result of poor motor design.
