and other system.

  • 2-way unmixed pump unit 3/4"

     

     

    DN20 pump units can be connected to heating systems with powers up to 35kW, with very low energy consumption assured by high efficiency synchronous circulating pumps. The connections to the distribution headers are made in ¾” thread (male on the distributor side and female on the loop side).

     

    Measurements: 180x302x142 mm (EPP insulation box)
    Centre distance: 90 mm
    Circulating pump: Grundfos UPM3 AUTO L 15-70

     

    Compact and up-to-date, the new series offers functions similar to those of the bigger sizes DN25 and DN32. Especially suitable to manage medium-low powers in small rooms, thanks to its centre distance of only 90 mm.

    For power up to: 35kW (Δt 20K).
    Maximum flow 1500 l/h.
    Kvs value: 6.0

     

    Approximate data calculated with a 6 m nominal lifting power circulating pump.

     

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

     

    Supply:

    • Connection 3/4”
    • Flanged ball valve with T-handle.
    • 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:

    • Flanged ball valve with non return valve 20 mbar (which can be excluded by rotating thehandle by 45°) supplied with in-handle thermometer (coded blue; 0°C-120°C).
    • Connection 3/4”

     

    For an accurate measuring or for higher flows, please refer to the curve.
