Circolatori in bronzo per acqua calda sanitaria / Bronze circulating pumps for sanitary hot water Pompe in bronzo per ricircolo di acqua calda sanitaria con bocche di aspirazione e di mandata dello stesso diametro e disposte sullo stesso asse (in-line). I modelli CR 20 e CRZ 30 hanno le bocche filettate, i modelli CRZ 40 e CRZ 50 hanno le bocche flangiate. I circolatori devono essere installati solo con l’albero motore in posizione orizzontale. Bronze pumps for sanitary hot water circulation with suction and delivery connections with the same diameter and on the same axis (in-line). The models CR 20 and CRZ 30 are made with screwed connection, the models CRZ 40 and CRZ 50 are made with flanged connections. The circulating pumps should be installed with horizontal shaft only.
