Product Overview
Suburban sports clubs and fitness gyms balancing peak post-workout showers rely on the Hydro Multi-E 3 CRE 45-2. Three Grundfos CRE 45-2 multistage pumps work in unison on the base frame, modulating rotational speed to follow the facility draw curve. Everything is ordered under the single manufacturer part number 93328664.
The engineered pump set achieves flow rates up to 3500 L/min at full speed. The vertical stage assembly can build up to 75 metres of head for steep elevations. Integrated Multi-Master intelligence coordinates the pumps without requiring an external control panel, ensuring automatic role swapping and uninterrupted pressure stabilization.
Factory mounted on an anti-vibration skid, the set incorporates stainless steel manifolds, two 200 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 77.4 A (3 x 25.8 A per pump). Motors carry IP54 sealing with maximum pressure of 10 bar. Liquid-temperature suitability is 5°C to 60°C, and inlet pressure is rated to 10 bar.
Proven across major commercial facilities like mixed-use commercial buildings, corporate office towers and shopping centres, the system runs with minimal maintenance. 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.
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- 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.
- Each main pump is rated 15 kW (P2), so per-pump draw scales down as speed follows demand.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Maximum operating pressure of 10 bar with motors sealed to IP54.
- 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.
- The system pairs three CRE 45-2 pumps in parallel duty, controlled as a single coordinated system.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Stainless steel manifolds provide two 200 mm manifold connections ready for plant pipework.
