Centrifugal pump casing for a circulating pump for two fluid circuits

摘要

The casing (1) has a supply chamber with an inlet channel (7) and two outlet channels (10,11) for the two circuits. The supply chamber is separated into two impeller chambers (2,3) communicating with the inlet channel, each with a motor-driven pump impeller. One outlet channel is provided for each impeller chamber for each circuit.
