Product Overview
Suburban wellness spas and hydrotherapy treatment clinics depend on the Hydro Multi-E 3 CRNE 10-5. Three Grundfos CRNE 10-5 multistage pumps work in unison on the base frame, modulating rotational speed to follow the facility draw curve. Part number 99752290 provides the complete tested package in a single order line.
Volumetric delivery peaks at 905 L/min to maintain fixture velocity. Multistage vertical hydraulics produce up to 74 metres of maximum head. Integrated Multi-Master intelligence coordinates the pumps without requiring an external control panel, ensuring automatic role swapping and uninterrupted pressure stabilization.
Pre-plumbed on a shared fabricated frame, the booster 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 13.3 A (3 x 4.43 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.
Routine installation environments span mixed-use commercial buildings, corporate office towers and shopping centres, where reliable clean-water pressure is required. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- Stainless steel manifolds provide two 80 mm manifold connections ready for plant pipework.
- At P2 each main pump is 2.2 kW, covering the duty without oversizing the frame.
- The system protects its pumps against dry running if the incoming supply is lost.
- Maximum operating pressure of 10 bar with motors sealed to IP55.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Three Grundfos CRNE 10-5 vertical multistage pumps run in parallel on one common base frame.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
