Product Overview
Secondary school campuses and boarding hostels manage peak morning basin demand with the Hydro Multi-E 2 CRNE 32-1. Two Grundfos CRNE 32-1 multistage pumps work in unison on the base frame, modulating rotational speed to follow the facility draw curve. Specify part number 93368405 and the complete factory-tested package arrives ready for connection.
With all pumps staged, maximum discharge reaches up to 1600 L/min. To pressurise elevated upper levels, the pumps develop up to 29 metres of head. Integrated Multi-Master intelligence coordinates the pumps without requiring an external control panel, ensuring automatic role swapping and uninterrupted pressure stabilization.
Factory configured for swift mechanical connection, the set features stainless steel manifolds, two 100 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 5.6 A (2 x 2.8 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.
Operating duty covers commercial complexes like mixed-use commercial buildings, corporate office towers and shopping centres, where sudden fixture demand occurs. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- Stainless steel manifolds provide two 100 mm manifold connections ready for plant pipework.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- Dry-running protection is built into the control, protecting the pumps if the suction supply is interrupted.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Two Grundfos CRNE 32-1 pumps share the boosting work in parallel.
- Each main pump is rated 2.2 kW (P2), so per-pump draw scales down as speed follows demand.
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Maximum operating pressure of 10 bar with motors sealed to IP54.
- Pump staging follows demand automatically: pumps enter at low speed as pressure drops, ramp to equal speed, and exit as flow fades.
- 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.
