M2 MIX3 - DN25

2-Way pump unit with 3-way mixing valve

The unit for 1” (180 mm) circulating pumps consists of:


  • Connection.
  • 3-way mixing valve.
  • High efficiency synchronous pre-wired circulating pump (for the models that include it).
  • Flanged ball valve supplied with in-handle thermometer (coded red, range 0°C-120°C).


  • Flanged ball valve with non return valve 20 mbar (which can be excluded by rotating the handle by 45°) supplied with in-handle thermometer (coded blue; 0°C-120°C).
  • “T” Connection for mixing valve.
  • Connection.

Centre distance 125 mm. EPP insulation box (Measurements: 250x380x170 mm).
PN 10, max temperature 110°C (unit without pump).
External connections:  1” Female.

For power up to 35 kW (with Δt 20 K) and maximum flow 1500 l/h.
Kvs Value: 6,0.
Approximate data calculated with a 6 m nominal lifting power circulating pump.
For an accurate measuring or for higher flows, please refer to the curves shown in the technical section.
Available circulating pumps:
Wilo Yonos Para RS 25/6 (Y6)
Grundfos UPM3 Auto L 25-70 (UL7)
Wilo Yonos Para RS 25/7,5 (Y8)

We suggest you to install two isolating valves Art. 552 (see Correlated Articles) before the pump unit to allow an easy service or replacement of the components of the unit.

Servomotor M21: 3 points servomotor for mixing valve. Bidirectional, reversible with fixed limit switches for an operating range of 90°. 230V, 2 min., torque: 5 Nm. IP42.
Several models available: see the section “Servomotors”.

AHC20 servomotor: basic climatic controller with servomotor and outside sensor, with climatic regulation for mixing valve with electronic control to keep fixed the selected temperature of the room. Bidirectional, reversible with fixed limit switches for an operating range of 90°, 2 min., torque: 6 Nm. Power supply 230V. IP42.

CMP25-2 climatic controller: “touch screen” climatic controller with servomotor for mixing valve, 3 points. Bidirectional, reversible with fixed limit switches for an operating range of 90°. 230V, 2 min., torque: 10 Nm. IP42.

Versions available with reduced Kvs (using the special kits, see Correlated Articles). In the table below the resulting Kvs of the unit is shown, with the relevant maximum values of power and flowrate:

Mixing valve Kvs
Pump unit Kvs
Power Flow rate
 10,0 (standard) 6,0 (standard) 35 kW 1500 l/h
6,3 5,0 29 kW 1250 l/h

2,5 2,4 14 kW 600 l/h

Measuring and check of a DN25 system

  Clicking on the icon at side it is possible to download an Excel file dealing with the measuring and the check of a DN25 pump unit; it is possible to select the model and the working parameters, so getting a check of the power and of the residual lifting power.In case of underfloor heating system the surface that can be managed is approximately calculated. Changing the starting data it is possible to simulate different employment situations and to make your considerations.
