Product Overview
State forestry depots and regional nursery facilities rely on the Hydro Multi-E 3 CRNE 10-1. Configured with three CRNE 10-1 vertical pumps in parallel, the booster dynamically matches motor speed to immediate water requirements. Specify part number 99752269 and the complete factory-tested package arrives ready for connection.
Peak flow velocity supports draw rates up to 750 L/min across the header. To pressurise elevated upper levels, the pumps develop up to 14 metres of head. Integrated Multi-Master intelligence coordinates the pumps without requiring an external control panel, ensuring automatic role swapping and uninterrupted pressure stabilization.
Engineered on a common steel baseplate, the package includes 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 4.41 A (3 x 1.47 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.
Specified across commercial properties including mixed-use commercial buildings, corporate office towers and shopping centres, the booster operates with top efficiency. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Three Grundfos CRNE 10-1 pumps share the boosting work in parallel.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- The system protects its pumps against dry running if the incoming supply is lost.
- Rated 0.55 kW (P2) on every main pump in the frame.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Stainless steel manifolds provide two 80 mm manifold connections ready for plant pipework.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- Maximum operating pressure of 10 bar with motors sealed to IP55.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
