M3 MIX3 FIX - DN25

3-Way pump unit with by-pass and 3-way mixing valve with electronic servomotor for the constant temperature. Heating and Cooling.

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

SUPPLY:

  • Connection.
  • 3-way mixing valve with electronic servomotor.
  • High efficiency synchronous pre-wired circulating pump (for the models that include it).
  • 3-way 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.

Balancing by-pass valve (0-0,5 bar).

RETURN:

  • 3-way 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” or 1”1/4 Female.

FIELD OF UTILIZATION:
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 (U7)
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.

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 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.
