The proven first-generation high-efficiency service water pump performs dependably in small to medium domestic hot water circulation systems.
The AX... BLUE Series domestic hot water circulation pumps offer convincing features such as long service life, high efficiency and high torque for prevention of limescale-related pump blockage. Thanks to its constant-pressure operating mode, the pump perfectly regulates the variable demand in systems with multiple circulation branches. For systems with only one branch there are three constant speeds to choose from.
