Grundfos Hydro MPC-E Triple Variable Speed Booster Set with 3 × CRIE 20 Stainless Steel Pumps (Max 1750 LPM, Three Phase)

The Grundfos Hydro MPC-E Triple CRIE 20 Series is a high-efficiency, fully integrated variable speed pressure boosting system, engineered for precise, energy-saving water supply in commercial and industrial applications.

Each Hydro MPC-E package is supplied as a complete plug-and-pump assembly with three CRIE 20 multistage stainless steel pumps, stainless steel suction and discharge manifolds, isolation and non-return valves for each pump, and a robust common base frame. The system comes fully equipped with a factory-configured intelligent CU 352 controller for automatic cascade control, pump sequencing, and real-time constant pressure adjustment based on actual demand.

Grundfos premium efficiency MGE motors (IE5 to 11 kW, IE3 for 15–22 kW) ensure ultra-low energy consumption, while integrated VSD technology maintains stable system pressure, optimising pump speed and duty points at all times. Automatic pump changeover, soft pressure build-up, integrated dry-running protection, alarm logs, and real-time monitoring provide safe, reliable operation with minimal intervention.

Ideal for commercial buildings, industrial water supply, irrigation or process applications requiring dependable constant pressure and maximum efficiency, the Hydro MPC-E Triple CRIE 20 delivers reliable flow up to 1750 LPM — all in a compact, pre-assembled booster package ready for easy installation.
