DN20 Pump units

ModvlvS DN20 pump units


Compact and up-to-date, the new ModvlvS DN20 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.
DN20 pump units can be connected to heating systems with powers up to 35kW, with a very low energy consumption assured by high efficiency synchronous circulating pumps.
The connections to the distribution headers are made in 3/4” thread (male on the distributor side and female on the loop side). The range is supplemented by: distributors, connections, security units, mixers and servomotors.
