Product Overview
Where holiday units and boutique apartment blocks juggling showers at the morning peak are served from a single booster, the Hydro Multi-E 3 CRE 3-8 holds pressure steady as three CRE 3-8 pumps respond to changing flow. Quote part number 99614251 to have it arrive pre-configured and ready for the plant room.
This set provides up to 237 L/min of flow capacity. Variable-speed operation can develop up to 73 metres of head where required. Because every pump carries its own frequency converter and the Multi-Master software elects the controlling pump itself, losing a control unit or pressure sensor means seamless handover rather than a shutdown.
The three-pump package arrives as one base-mounted assembly with stainless steel manifolds, two 50 mm manifold connections, valves, sensors and a pressure gauge, plus a 24L diaphragm tank. Electrical supply is 1 x 200-240 V at 50 / 60 Hz with a rated current of 13.5 A. The motors have IP54 protection and the system is rated to 10 bar maximum pressure. Liquid-temperature suitability is 5°C to 60°C. Inlet pressure is rated to 10 bar.
Expect it on industrial process supply and hotel plant rooms sites, plus aged-care complexes duties. It provides clean-water pressure boosting for both new plant rooms and refits.
Features
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Frequency converters on the motors pair with IE5 permanent magnet motors for efficient part-load operation.
- At P2 each main pump is 0.75 kW, covering the duty without oversizing the frame.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- The stainless steel manifold assembly is supplied with two 50 mm manifold connections.
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- Maximum operating pressure of 10 bar with motors sealed to IP54.
- Three Grundfos CRE 3-8 vertical multistage pumps run in parallel on one common base frame.
- Slow-speed duty and staged switching keep consumption down through low-demand hours.
- 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 phone.
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.
