Product Overview
Commercial laundry facilities running continuous hot water cycles depend on the heavy-duty Hydro Multi-E 2 CRNE 64-2-2 package. The package operates two Grundfos CRNE 64-2-2 vertical multistage pumps in parallel, automatically staging each unit as flow demand increases. Specify part number 93368441 and the complete factory-tested package arrives ready for connection.
System discharge handles up to 3400 L/min for heavy commercial usage. To pressurise elevated upper levels, the pumps develop up to 59.2 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.
Engineered for straightforward mechanical hookup, the package supplies stainless steel manifolds, two 150 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 51.6 A (2 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 in continuous duty across installations including high-rise apartments, hotel plant rooms and schools and universities, the system delivers quiet operation. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- 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.
- Two Grundfos CRNE 64-2-2 vertical multistage pumps run in parallel on one common base frame.
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with 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.
- At P2 each main pump is 11 kW, covering the duty without oversizing the frame.
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.
- Stainless steel manifolds provide two 150 mm manifold connections ready for plant pipework.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
