WATER SOUND DC1.7-20 Silent Booster Pump
Quiet, intelligent and frequency-controlled pressure boost for domestic water lines.
WATER SOUND DC1.7-20 Silent Booster Pump is engineered to deliver comfortable water supply in apartment networks, solar energy systems and low-pressure lines. In addition, its intelligent magnet motor and integrated frequency drive start the unit automatically when a tap opens and stop it when the tap closes. Moreover, a three-stage power setting lets you choose low, medium or high performance to match demand.
This unit has no self-priming capability, so the inlet line must be filled with water. It connects directly to the line and raises incoming mains pressure to the ideal level. A CCS button senses flow rate and dynamically optimizes operating speed. Furthermore, it converts 220V mains electricity into safe 24V DC via the supplied adapter, consuming 85 W. It handles fluids from 0°C to +90°C and ambient temperatures from 0°C to +45°C, with a maximum inlet pressure of 0.5 bar. Connections are 3/4″ threaded inlet and outlet, and the net weight is 2.5 kg. At 0 m³/h it delivers 20 m head; at 1.6 m³/h it delivers 2 m head.
