M2 MIX3 CS - DN32

2-Way pump unit for solid fuel boilers with electronic servomotor for the control of the return temperature

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


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


  • 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 blue, range 0°C-120°C).
  • Temperature sensor.

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 111 kW (with Δt 20 K) and maximum flow 4800 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 curves.
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) after the pump unit to allow an easy service or replacement of the components of the unit.
puffer /
heating installation
solid fuel boiler
The unit, by means of a 3-way mixing valve operated by a servomotor with controller, always keeps the return temperature above the condensing temperature, preventing the deposits both in the boiler and in the flue, improving its performance and life.

The electronics of servomotor keeps constant the set temperature of the return 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.

Adjustment of target temperature adjustable from 0°C up to 99°C.
Operating range of 90°.
Power supply 230V, 2 min, torque 6 Nm. IP42.
