The GREENPRO GR-370 circulation pump is a reliable and energy-efficient solution for residential and small commercial heating and domestic hot-water systems. Built using modern German technology, the pump ensures stable coolant circulation in closed loops at temperatures up to 110°C and pressures up to 10 bar.
Thanks to its compact size, low weight, and flanged connection, the GR-370 can be easily installed in confined spaces — boiler rooms, technical shafts, and service areas. The pump operates almost silently, making it ideal for residential use.
Advantages
▪️ Optimized energy consumption — reduced operating costs.
▪️ Near-silent operation due to modern motor design.
▪️ Allows the use of smaller-diameter pipes, reducing system cost.
▪️ Robust cast-iron hydraulics resistant to corrosion and overheating.
▪️ Easy installation and maintenance.
Applications
Small houses, apartments, private boiler rooms, underfloor heating, DHW circulation systems, and compact radiator networks.
