DN32 Pump units
 DN32 pump units, thanks to a very careful measuring of the specific components, have all the force points of ModvlvS range, such as functional capacity, reliability and versatility of installation. They can be connected to heating systems with powers up to 111 kW, with a very low energy consumption assured by high efficiency synchronous circulating pumps Wilo Stratos Para and Grundfos Alpha 2L. the connections to the heating loop or to the distributor are made in 1”1/4 female thread. |

| The overpressure control is given by the self-regulating pump units which, thanks to the integrated control of the differential pressure at constant ∆p or variable ∆p, allow to equalize the performances and the efficiency of M3 pump units of DN25 series even in presence of very high flows (up to 4.800 l/h). In the diagram at side you can see the typical curves of Wilo Stratos Para 30/1-8 circulating pump in the two available working modes. |
