Grundfos Hydro Multi-E is an energy‑efficient pressure boosting system for clean water, consisting of 3 parallel‑connected, frequency‑controlled CRE 5‑4 multistage centrifugal pumps mounted on a black‑painted mild steel base frame. The unit delivers a maximum flow of 30.6 m³/h and a maximum head of 39 m. The inlet and outlet manifolds are made of AISI 316 stainless steel, connections are R2 internal thread per DIN ISO 7/1, and the system includes a diaphragm tank (24 l), isolating valves, non‑return valve, pressure gauges, and two pressure transmitters. Each pump is driven by an IE5 high‑efficiency PM motor (P2 = 0.75 kW, IP54, 1 x 200‑240 V, 50/60 Hz). The integrated PI controller maintains constant pressure regardless of flow variations and can be operated via the graphical display or Grundfos GO.
