Product Overview
Suburban childcare centres requiring gentle, stable warm-water pressure choose the Hydro Multi-E 3 CRNE 5-2. Staged parallel operation between three CRNE 5-2 pumps maintains consistent line pressure without erratic cycling. Ordering part number 99752201 puts the fully tested booster skid directly onto the plant room floor.
Discharge volume reaches up to 510 L/min across the entire facility. Up to 20 metres of delivery head is available to keep upper-floor fixtures pressurised. Advanced Multi-Master firmware shares operating duties directly between pump heads, providing immediate fail-safe handover if an individual drive is isolated.
Constructed as a pre-tested boosting skid, the package brings together stainless steel pipework, two Rp 2 inch threaded 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 package ensures dependable pressure delivery across food production facilities, logistics distribution hubs and aquatic sports centres, eliminating line surges. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.
- Energy draw matches the actual job because speed follows demand, not a fixed curve.
- Stainless steel manifolds provide two Rp 2 inch threaded manifold connections ready for plant pipework.
- Pump staging follows demand automatically: pumps enter at low speed as pressure drops, ramp to equal speed, and exit as flow fades.
- Maximum operating pressure of 10 bar with motors sealed to IP55.
- 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.
- Each main pump is rated 0.55 kW (P2), so per-pump draw scales down as speed follows demand.
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- The system pairs three CRNE 5-2 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.
- 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.
