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.

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
