Product Overview
The Hydro Multi-E 3 CRE32-2 is a proven fit for stadium amenities and convention centres that fill to the brim in short bursts, with three Grundfos CRE 32-2 pumps staged automatically as demand varies. Specify part number 93320237 and the whole set lands tested, assembled and ready for pipework.
The system supports flow rates up to 2317 L/min. It can develop up to 57 metres of head for dependable pressure boosting. Because every pump carries its own frequency converter and the Multi-Master software elects the controlling pump itself, losing a control unit or pressure sensor means seamless handover rather than a shutdown.
Factory assembled on a common base, the set combines stainless steel pipework, two 150 mm manifold connections, isolation and non-return valves, pressure sensors and a gauge, plus a 24L diaphragm tank. It connects to a 3 x 380-415 V supply at 50 / 60 Hz with a rated current of 40.9 A. Motors are protected to IP54, while maximum system pressure is 10 bar. Liquid-temperature suitability is 5°C to 60°C. Inlet pressure is rated to 10 bar.
Its home ground covers industrial process supply, high-rise apartments and schools and universities. The variable-speed system suits clean-water boosting duties with changing demand.
Features
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a phone.
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- The set ships with an 24L precharged diaphragm tank for low-flow stability.
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- Stainless steel manifolds provide two 150 mm manifold connections ready for pipework.
- The system protects its pumps against dry running if the incoming supply is lost.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Three Grundfos CRE 32-2 vertical multistage pumps run in parallel on one common base frame.
- At P2 each main pump is 5.5 kW, covering the duty without oversizing the frame.
- Maximum operating pressure of 10 bar with motors sealed to IP54.
