The HERZ-PUMPFIX MIX BASIC pump group is used in heating systems and cooling water systems. The pump group regulates the temperature of the heating circuit via electronic regulation. Built-in 3-way valve mixes hot supply and cold return to the desired temperature. It is possible to install circulation pumps of various manufacturers and types.
The main uses of the HERZ- PUMPFIX MIX BASIC pump group:
- systems with surface heating
- combined heating systems
The DN25 HERZ PUMPFIX BASIC pump group can be upgraded with a safety valve (1 4514 99) for additional functionality.

Heating water according to ÖNORM H5195 or VDI- Standard 2035. The use of ethylene, or propylene glycol in a mixing ratio of 25- 50% is allowed. EPDM gaskets can be affected by Mineral oils lubricants and thus lead to failure of the EPDM seals. Please refer to the manufacturers documentation when using ethylene glycol products for frost and corrosion protection.
