Product Overview
Suburban day surgery facilities requiring uninterrupted theater wash supply depend on the Hydro Multi-E 3 CRNE 10-1. Three Grundfos CRNE 10-1 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 99752265.
Volumetric throughput easily extends up to 750 L/min as fixtures multiply. The vertical stage assembly can build up to 14 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.
Pre-packaged as an integrated pumping assembly, the system features stainless steel manifolds, two 80 mm manifold connections, isolation and non-return valves, pressure sensors, plus a 24L diaphragm tank. It connects to a 1 x 200-240 V supply at 50 / 60 Hz with combined rated current of 10 A (3 x 3.33 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 easily accommodates water demand across mixed-use commercial buildings, corporate office towers and shopping centres, scaling smoothly as fixtures open. 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 main pump is rated 0.55 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.
- Variable speed comes from frequency converters matched to IE5 permanent magnet motors, keeping the booster set in its efficient range.
- The system pairs three CRNE 10-1 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.
- Slow-speed duty and staged switching keep consumption down through low-demand hours.
- Pump staging follows demand automatically: pumps enter at low speed as pressure drops, ramp to equal speed, and exit as flow fades.
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
- Stainless steel manifolds provide two 80 mm manifold connections ready for plant pipework.
- 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.
