Grundfos Hydro MPC-E Dual CRIE15 Automatic Variable Speed Pressure Boosting Pump Set (Max 900LPM)

The Grundfos Hydro MPC-E Dual CRIE 15 Series is a compact, fully integrated variable speed booster pump system designed to deliver reliable, energy-efficient constant pressure for commercial buildings, process water supply, irrigation, and light industrial systems.

Each Hydro MPC-E Dual CRIE 15 is supplied as a complete plug-and-pump package with two CRIE 15 multistage stainless steel pumps, twin stainless steel suction and discharge manifolds, individual isolating and non-return valves for each pump, and a robust common base frame. The intelligent CU 352 controller provides fully automatic cascade control, pump sequencing, and real-time variable speed adjustment to maintain constant pressure — even as demand fluctuates.

Grundfos MGE IE5 motors (up to 11 kW) or IE3 motors (15–22 kW) deliver maximum energy efficiency with ultra-quiet operation. Integrated variable speed drive (VSD) technology ensures stable system pressure while optimising pump duty for low power consumption and minimal wear. Features like automatic pump changeover, soft pressure build-up, dry-running protection, alarm logging and optional remote monitoring guarantee dependable daily operation with minimal manual oversight.

Ideal for mid-sized sites that need dependable constant pressure at low operating cost, the Hydro MPC-E Dual CRIE 15 delivers flows up to 900 LPM — all in a space-saving, pre-assembled booster set ready for fast installation and simple servicing.
