Pumpfix DN20 COMPACT
The compact pump group is designed for efficient management of two separate heating circuits and represents an ideal solution for systems with heat pumps, boilers, or a combination of radiators and underfloor heating, suitable for heated areas of up to approximately 150 m².
It includes a high-efficiency circulation pump, ball valves with thermometers, a check valve, thermal insulation, and a manifold with the possibility of hydraulic balancing of the system.
Its well-thought-out design allows for easy installation, fast servicing, and the option to expand the system with an additional mixing kit.
