M2 MIX3 FIX - DN32

2-Way pump unit with 3-way mixing valve with electronic control for the constant temperature. Heating and Cooling.

The unit for 1” 1/4 (180 mm) circulating pumps consists of:


  • Connection.
  • 3-way mixing valve with electronic servomotor.
  • 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).
  • Temperature sensor.
  • Bimetallic unipolar thermostat, 20÷90°C, with contact by interruption or switching.


  • Flanged ball valve supplied with in-handle thermometer (coded blue; 0°C-120°C).
  • “T” Connection for mixing valve with 20 mbar non return valve (ball valve side).
  • Connection.

Centre distance 125 mm. EPP insulation box (Measurements: 250x400x170 mm).
PN 10, max. temperature 110°C (unit without pump).
External connections:  1”1/4 Female.

For power up to 93 kW (with Δt 20 K) and maximum flow 4000 l/h.
Kvs Value: 13,0.
Approximate data calculated with a 8 m nominal lifting power circulating pump (Wilo Stratos PARA 30/1-8). For an accurate measuring or for higher flows, please refer to the diagram.
Synchronous circulating pumps:
Grundfos Alpha 2L 32-60 (A6)
Wilo Stratos PARA 30/1-7 (P7)
Wilo Stratos PARA 30/1-8 (P8)

We suggest you to install two isolating valves Art. 55AMMS with nut and gasket (see Correlated Articles) before the pump unit to allow an easy service or replacement of the components of the unit.
The electronics of servomotor keeps constant the set temperature of the supply way, monitoring it by means of a sensor (included) mounted on the pipe. Display of the measured temperature and target temperature, on reversible LCD display.
Setting of target temperature adjustable from 0°C up to 99°C. Operating range of 90°.
Power supply 230V, 2 min, torque 6 Nm. IP42

Measuring and check of a DN32 system

  Clicking on the icon at side it is possible to download an Excel file dealing with the measuring and the check of a DN32 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.
