Product Overview
Cafe strips and small assemblies where a dishwasher cycle drops the street pressure rely on booster systems with no tolerance for pressure variation, and the Hydro MPC-E 3 CRNE 5-2 is engineered for exactly that duty. One factory-tested package replaces a shelf of loose components; order part number 93637781 to put it on site.
It handles flows up to 493 L/min across the system. The pumps can develop up to 19 metres of head when pressure demand increases. A Grundfos GENIECON PANEL on the common base frame provides the system control; the GENIECON UNIT within it holds the exact hydraulic and electrical data of the pumps, so staging and changeover decisions are based on the pumps' actual curves.
The three-pump package arrives as one base-mounted assembly with stainless steel manifolds, two 50 mm manifold connections, valves, sensors and a pressure gauge, plus an 8L diaphragm tank. Electrical supply is 3 x 230 V at 50 Hz with a rated current of 6.7 A. The motors have IP54 protection and the system is rated to 16 bar maximum pressure. Liquid-temperature suitability is 5°C to 60°C.
Its home ground covers commercial buildings, water supply networks and irrigation schemes. The variable-speed system suits clean-water boosting duties with changing demand.
Features
- Rated 0.55 kW (P2) on every main pump in the frame.
- Energy draw matches the actual job because speed follows demand, not a fixed curve.
- Inlet pressure monitoring provides dry-running protection if the suction supply is insufficient.
- The stainless steel manifold assembly is supplied with two 50 mm manifold connections.
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.
- Pump staging follows demand automatically: pumps enter at low speed as pressure drops, ramp to equal speed, and exit as flow fades.
- The system pairs three CRNE 5-2 pumps in parallel duty, controlled as a single coordinated system.
- Control decisions come from real pump curves, not generic models, via the GENIECON UNIT.
- The touch-panel GENIECON interface shows system status and allows direct setpoint changes on the door.
- The set ships with an 8L precharged diaphragm tank for low-flow stability.
- Variable speed comes from frequency converters matched to permanent magnet motors, keeping the booster set in its efficient range.
- The package is wet-tested and pre-configured, requiring only pipework and power on site.
- Maximum operating pressure of 16 bar with motors sealed to IP54.

How much discharge water flow does this variable speed booster unit supply across the distribution ringmain?
Operating across its factory curve, the Grundfos Hydro MPC-E 3 CRNE 5-2 VN GA-A-A-AG discharges up to 493 L/min of clean water to maintain consistent line pressure during peak demand cycles.
Which electric motor drive configuration powers each centrifugal pump within this booster package?
Each centrifugal stage of the Hydro MPC-E 3 CRNE 5-2 is driven by a 0.55 kW variable frequency drive MGE electric motor running on 3 x 230 V power, utilizing built-in variable speed drives to adjust output dynamically.
Which vertical elevation head and system pressure rating applies to this multi pump skid?
Elevating water across multi-level pipework, the Hydro-MPC-E-3-CRNE-5-2 maintains up to 19 m total dynamic head with an overall 16 bar maximum operating limit.
What plumbing connection dimensions and manifold check valves are installed on this assembly?
Plumbed for rapid site installation, the Hydro MPC E 3 CRNE 5 2 includes R 2" stainless steel headers equipped with dedicated isolating valves, check valves, and pressure transmitters.
How is this variable speed booster skid supported by Grundfos manufacturer warranty?
Grundfos provides two-year manufacturer warranty coverage on the 3 CRNE 5-2 (Hydro MPC-E), securing the complete multi-pump package, manifolds, and integrated electronics.
