It combines the HRE-03 helical hydraulics—specialized in generating high pressure with moderate flow rates—with a brushless ECDrive motor from the 600 series. This configuration allows for a reference flow rate of \u003cstrong\u003e0.45 m³\/h\u003c\/strong\u003e and can reach up to \u003cstrong\u003e120 m\u003c\/strong\u003e of manometric head, making it ideal for elevated tanks, long pipelines, or installations with significant elevation differences. Its construction in \u003cstrong\u003eAISI 304\/316 stainless steel\u003c\/strong\u003e and the integrated \u003cstrong\u003echeck valve\u003c\/strong\u003e ensure reliability, protection of the water column, and a long service life.
