DN25 Pump units

ModvlvS DN25 pump units


The ModvlvS DN25 series is a complete range that meets all the installation needs with specific models: middle and low temperature heating systems, need of energy metering, cooling systems; everything with the possibility of a management control by means of climatic controllers even built-in the pump unit.
The DN25 pump units can be connected to heating systems with powers up to 50 kW, with a very low energy consumption assured by high efficiency synchronous circulating pumps.
The connections to the distribution headers are made in 1” or 1”1/4 female thread. Moreover the pump units of M3 version are equipped with a by-pass balancing valve that allows an accurate regulation of the differential pressure of the loop. The range is supplemented by: distributors, connections, security units, mixers and servomotors.
