Product Overview
Veterinary hospital suites and animal care boarding facilities choose the Hydro Multi-E 2 CRNE 5-8. The package operates two Grundfos CRNE 5-8 vertical multistage pumps in parallel, automatically staging each unit as flow demand increases. Specify part number 99752240 and the complete factory-tested package arrives ready for connection.
Handling substantial simultaneous demand, flow achieves up to 340 L/min. To pressurise elevated upper levels, the pumps develop up to 79 metres of head. Because every pump carries its own frequency converter and Multi-Master software elects the controlling pump itself, losing a control unit or pressure sensor means seamless handover rather than a shutdown.
Delivered as a self-contained pumping skid, the assembly 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 3 x 380-415 V supply at 50 / 60 Hz with combined rated current of 6.2 A (2 x 3.1 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 provides robust pressure boosting across high-rise apartments, hotel plant rooms and schools and universities, supporting busy peak trading. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- The system pairs two CRNE 5-8 pumps in parallel duty, controlled as a single coordinated system.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- Slow-speed duty and staged switching keep consumption down through low-demand hours.
- The system protects its pumps against dry running if the incoming supply is lost.
- Variable speed comes from frequency converters matched to IE5 permanent magnet motors, keeping the booster set in its efficient range.
- Maximum operating pressure of 10 bar with motors sealed to IP55.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Stainless steel manifolds provide two Rp 2 inch threaded manifold connections ready for plant pipework.
- At P2 each main pump is 1.5 kW, covering the duty without oversizing the frame.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
