Wet Rotor Circulator BMH 30/340.65T - Code 505940622

Wet Rotor Circulator BMH 30/340.65T – Three-phase 400V – Max. flow rate 14 m³/h – Max. head 12 m – Code 505940622

The BMH 30/340.65T is a three-phase wet rotor circulator , designed for water circulation in both civil and industrial heating and air conditioning systems . Robust, silent and reliable, it is perfect for high-efficiency collective systems, thanks to its configuration with a 4-pole asynchronous motor , adjustable to 3 speeds at 400 V.

The compact design and high-quality materials guarantee durability , corrosion resistance and reduced maintenance , even in the presence of glycol mixtures up to 30%.

Main applications

✅ Central heating systems
✅ Industrial air conditioning and cooling systems
✅ Water circulation in collective civil systems
✅ Solutions for thermal power plants, boilers and heat pumps
