tubra®-PGM / PGR S
Heating circuit groups DN 20
The compact pump groups for mixed and unmixed heating circuits
up to 45 kW heating output.
- large power range up to 45 kW
- Progressive mixer characteristic curve for large volume flow range
with optimum control quality (DN 20 kvs = 0 – 4.5 m³/h) - integrated temperature sensors – position in flow and return
- smooth running ball valves with floating ball
- Integrated adapter for heat meter or
tubra®-mag-jet magnetite separator - thermal insulation compliant with GEG
- Suitable for cooling applications > 14°C through transparent film
in front of the thermometer openings

tubra®-Trio-mat +
tubra®-PGM S
The compact pipe group for one mixed and one unmixed heating circuit with only one pump group.
- direct connection to a heat generator with integrated pump
- compact modular design
- completely pre-assembled for connection to the heating circuit
- lower operating costs, as there is no need for a pump in the unmixed heating circuit
- combination with system separation ensures minimum flow rate
