Pump groups DN25/DN32

The HK25 and HK32 pump groups are designed for unmixed heating circuits such as radiators. The HKM25/32, HKF25 and HKFC25 pump mixer groups are suitable for mixed heating circuits such as underfloor heating systems.

All DN25 and DN32 pump groups are designed for pumps with an installation length of 180 mm and have flat seals.

The 3-part patented heat insulation shell complies with GEG. The mixer groups are equipped with a 3-way mixing valve with actuator or a thermostatic mixing valve. The flow and return lines can be interchanged on site.

Boiler manifolds of the VB25/32 series enable the connection of 2 to 5 pump groups. Suitable hydraulic separators can be found here: Hydraulic Separators
