DESIGN FEATURES
The MCE/C frequency converter provides the circulation pump with extreme operational flexibility, automatically adapting the pump to various system requirements and maintaining a constant pressure drop in it.
The pump housing and motor support are made of cast iron. Connecting pipes – threaded 2"G. Impeller-technopolymer, mechanical seal-graphite/ceramic. The pumps are equipped with an air-cooled asynchronous electric motor: four-pole for ALME and two-pole for ALPE.
To ensure low noise levels and long service life service, the rotor rotates on oversized bearings filled with lubricant for the entire service life.The design of the electric motor complies with the requirements of CEI 2-3 standards.
