M2 DN20
2-way unmixed pump unit
The unit for 1/2” (130 mm) circulating pumps consists of:
Supply
• Connection.
• 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 (red ring, range
0°C-120°C).
Return
