Seal-less Magnetic Pumps Offer Versatility in Refrigeration Systems

WARRENDER seal-less magnetic process pumps safely handle toxic refrigerants as used in NH3, CO2, Freon or glycol based systems. Standardized close-coupled TEFC motors remove the hot windings from the process while meeting any electrical standard. Magnetic couplings meet zero emissions requirements with a minimized heat load or flashing. Warrender pumps are available in high flow circulation or low flow transfer designs.
