Circulation pump GREENPRO 25/4T-180
Technical characteristics
The GREENPRO 25/4T-180 is a high-efficiency circulation pump designed for heating systems with larger pipe diameters and enhanced hydraulics. With a 180 mm installation length, it is ideal for retrofitting and integrating into existing pipelines where high flow is required at moderate head pressure.
The pump can operate with heat carrier temperatures up to 110 °C and pressures up to 10 bar, offering long service life and excellent resistance to temperature fluctuations.
Advantages
▪️ Increased performance thanks to the 25 mm connection diameter.
▪️ Ideal for medium-sized single- and double-circuit heating systems.
▪️ Energy and fuel savings up to 30%.
▪️ Improved hydraulics — quiet, vibration-free operation.
▪️ Corrosion and scale protection; durable cast-iron housing.
▪️ Easy installation with 180 mm length, compatible with older piping configurations.
