    Pump unit with servomotor mixing valve 3/4”
    2-WAY PUMP UNIT WITH 3-WAY MIXING VALVE WITH BUILT-IN BY-PASS 0-50%

    DN20 pump units can be connected to heating systems with powers up to 33kW, with a very
    low energy consumption assured by high efficiency synchronous circulating pumps.

     

    EPP insulation box (Measurements: 180x302x142 mm).
    Centre distance 90 mm.
    Especially suitable to manage medium-low powers in small rooms,
    thanks to its centre distance of only 90 mm.
    For power up to 33 kW (with Δt 15 K).
    Maximum flow 1900 l/h.
    Kvs value: 5.5
    For an accurate measuring or for higher flows, please refer to the curves shown in the next page.

     

    The unit for 1/2” (130 mm) circulating pumps consists of:
    Supply:

    • Connection.
    • 3-way mixing valve with adjustable by-pass. Through the bypass
      (adjustable from the front part) it is possible to mix on the
      supply line a quantity of water coming back from the return
      line of the system, from 0 up to 50%.
    • 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).

    Return:

    • VFlanged 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.

    Working principle

     

    During the regular working process, with the mixer completely closed on the recy cling for example, a part of the fluid is aspirated from the pump all along the by-pass line. This quantity of fluid (narrow blue arrow) represents 50% of the capacity of the mixer (red arrow). As a result, one has a very high delivery capacity and a reduced temperature.

    Servomotor TRM20:

     

    3 points servomotor for mixing valve, bidirectional,
    reversible.
    Operating range of 90°, 230V, 105 s., torque 2 Nm. IP40.

     

     

     

     

     

     


     

     

     

    Euroster 11M

     

     

    Electronic, programmable controller designed for control of a three-way valve with actuator and CH circulation pump. It automatically maintains a constant temperature at a preset level or ensures a proper temperature of water in return piping in a CH system with coal-fired boiler. Possibility to connect a room thermostat. E11M controller is equipped with an AntiStop function which prevents seizure of the idle pump and valve rotor.

     

    Controller function

    • keeps constant water temperature: in the central heating
      circuit or in boiler return
    • possibility of connecting room regulator
    • Anti-Stop function to protect pumps and valve against
      stoppage
    • frost protection
    • pump operation test
    • temperature reading correction

     

    EUROSTER 11M operates in one of the two modes: heating medium temperature regulation (e.g. in floor heating) or return temperature stabilization. Operation mode is changed when restoring factory settings, provided for each of the modes.

    Set 1: intended for system with heating medium temperature regulation

    Set 2 intended for system with return temperature regulation
