Hydronic pump module

Hydronic pump module

The hydronic pump module is the perfect link between one or more eChillers and the hydraulic system of your application.

The module is designed for operation with water and water/glycol mixtures and is supplied as standard with the connections for a buffer tank, which is optionally available.
In a non-buffered operation, the pump hydraulic module is supplied with two circulating pumps, and a third circulating pump is used when operating with a buffer tank. This makes it possible to realize different volume flows on the primary and secondary side.

Technical features:

  • Two circulation pumps controlled by a frequency converter (three, if a buffer is used)
  • Electrically controlled 3-way valve to protect the cooling water circuit from frost with temperature sensors
  • Insulated piping made of stainless steel and non-ferrous metal
  • Machine side connection: 4 x Rp2
  • Connection consumer side:
    • Chilled water: 2 x Rp2
    • Cooling water: 2 x Rp2
  • Operating pressure: 10 bar


  • buffer tank (external)
  • pump configuration
