Product Overview
High-volume hotel laundry plants requiring immediate pressure recovery install the Hydro Multi-E 3 CRNE 5-8. Three Grundfos CRNE 5-8 multistage pumps work in unison on the base frame, modulating rotational speed to follow the facility draw curve. Specify part number 99752238 and the complete factory-tested package arrives ready for connection.
Peak discharge throughput easily reaches up to 510 L/min across plant feeds. To pressurise elevated upper levels, the pumps develop up to 79 metres of head. Integrated Multi-Master intelligence coordinates the pumps without requiring an external control panel, ensuring automatic role swapping and uninterrupted pressure stabilization.
Supplied pre-assembled on a steel base chassis, the set includes stainless steel manifolds, 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 26.3 A (3 x 8.77 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 commercial targets encompass mixed-use commercial buildings, corporate office towers and shopping centres, where quiet inverter operation is necessary. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- The system protects its pumps against dry running if the incoming supply is lost.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- Maximum operating pressure of 10 bar with motors sealed to IP55.
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.
- Three Grundfos CRNE 5-8 vertical multistage pumps run in parallel on one common base frame.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- 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.
- Each main pump is rated 1.5 kW (P2), so per-pump draw scales down as speed follows demand.
- Stainless steel manifolds provide two Rp 2 inch threaded manifold connections ready for plant pipework.
