Product Overview
For showers, coffee machines and dishwashers competing for one limited mains feed, a factory-assembled Hydro MPC-E 3 CRNE 5-4 package provides a well-matched solution, with three CRNE 5-4 pumps staged against the demand curve. Specify part number 93637786 and the whole set lands tested, assembled and ready for pipework.
The system supports flow rates up to 497 L/min. It can develop up to 38 metres of head for dependable pressure boosting. Control sits with the GENIECON multi-pump controller in its touch-equipped panel, adjusting each pump individually and rotating duty by load, run hours and faults.
Factory assembled on a common base, the set combines stainless steel pipework, two 50 mm manifold connections, isolation and non-return valves, pressure sensors and a gauge, plus an 8L diaphragm tank. It connects to a 3 x 230 V supply at 50 Hz with a rated current of 6.7 A. Motors are protected to IP54, while maximum system pressure is 16 bar. Liquid-temperature suitability is 5°C to 60°C.
Expect it on high-rise developments and industry sites, plus irrigation schemes duties. It provides clean-water pressure boosting for both new plant rooms and refits.
Features
- Rated 1.1 kW (P2) on every main pump in the frame.
- Three Grundfos CRNE 5-4 vertical multistage pumps run in parallel on one common base frame.
- Control decisions come from real pump curves, not generic models, via the GENIECON UNIT.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Rated for 16 bar system pressure; motors carry IP54 protection.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- Each pump is driven by permanent magnet motors with frequency-controlled speed matching demand.
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.
- GENIECON PANEL control with touch display gives operating staff full staging visibility.
- The set ships with an 8L precharged diaphragm tank for low-flow stability.
- Stainless steel manifolds provide two 50 mm manifold connections ready for pipework.
- Inlet pressure monitoring provides dry-running protection if the suction supply is insufficient.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
