Grundfos Hydro MPC-E Dual CRIE 3 Automatic Variable Speed Pressure Boosting Pump Set (Max 180LPM)

The Grundfos Hydro MPC-E Dual CRIE 3 Series is a compact, high-efficiency variable speed booster pump system designed to deliver constant, energy-efficient water pressure for smaller commercial buildings, domestic boosting, light industrial water supply and irrigation applications.

Each Hydro MPC-E Dual CRIE 3 package is supplied pre-assembled and factory-tested for true plug-and-pump installation. The system includes two CRIE 3 multistage stainless steel pumps, twin stainless steel suction and discharge manifolds, isolating and non-return valves for each pump, and a rugged common base frame. The intelligent CU 352 controller provides automatic cascade control, pump sequencing and real-time variable speed adjustment to maintain a steady system pressure, even as demand varies.

Grundfos MGE IE5 premium motors deliver exceptional energy savings, whisper-quiet operation and long service life. Integrated variable speed drive (VSD) technology keeps the system pressure stable and adjusts pump speed to match real-time demand — cutting energy costs and pump wear. Automatic pump changeover, soft pressure build-up, dry-running protection, full alarm logging and remote monitoring ensure safe, reliable daily performance with minimal intervention.

Compact yet powerful, the Hydro MPC-E Dual CRIE 3 is ideal for sites where dependable constant pressure and energy efficiency are essential — delivering up to 180 LPM in a small footprint that’s easy to install and service.
