Product Overview
Regional education hubs and tafe workshop facilities count on the Hydro Multi-E 2 CRNE 15-3. Two Grundfos CRNE 15-3 multistage pumps work in unison on the base frame, modulating rotational speed to follow the facility draw curve. Specify part number 99752332 and the complete factory-tested package arrives ready for connection.
Discharge volume easily satisfies draw-offs up to 933 L/min. To pressurise elevated upper levels, the pumps develop up to 62 metres of head. Integrated Multi-Master intelligence coordinates the pumps without requiring an external control panel, ensuring automatic role swapping and uninterrupted pressure stabilization.
Mechanically integrated on a heavy baseplate, the system combines stainless steel manifolds, two 80 mm manifold connections, isolation and non-return valves, pressure sensors, plus a 24L diaphragm tank. It connects to a 3 x 380-415 V supply at 50 / 60 Hz with combined rated current of 12.4 A (2 x 6.2 A per pump). Motors carry IP55 sealing with maximum pressure of 10 bar. Liquid-temperature suitability is 5°C to 60°C, and inlet pressure is rated to 10 bar.
The booster is widely deployed across mixed-use commercial buildings, corporate office towers and shopping centres, providing quiet, variable-speed pressure delivery. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Maximum operating pressure of 10 bar with motors sealed to IP55.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- At P2 each main pump is 3 kW, covering the duty without oversizing the frame.
- The system protects its pumps against dry running if the incoming supply is lost.
- Stainless steel manifolds provide two 80 mm manifold connections ready for plant pipework.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Slow-speed duty and staged switching keep consumption down through low-demand hours.
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Two Grundfos CRNE 15-3 pumps share the boosting work in parallel.
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
