Product Overview
State emergency service depots and maintenance hangars install the Hydro Multi-E 2 CRNE 15-1. Staged parallel operation between two CRNE 15-1 pumps maintains consistent line pressure without erratic cycling. Ordering part number 99752314 puts the fully tested booster skid directly onto the plant room floor.
Flow capacity peaks at 933 L/min to satisfy heavy institutional demand. Up to 21 metres of delivery head is available to keep upper-floor fixtures pressurised. Advanced Multi-Master firmware shares operating duties directly between pump heads, providing immediate fail-safe handover if an individual drive is isolated.
Factory aligned on a rigid steel base, the set brings together stainless steel pipework, two 80 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 4.74 A (2 x 2.37 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 set is engineered for commercial boosting duties across food production facilities, logistics distribution hubs and aquatic sports centres, eliminating pressure dips. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- Both constant-pressure and proportional-pressure modes are available, so plant rooms can tune response to pipework.
- Stainless steel manifolds provide two 80 mm manifold connections ready for plant pipework.
- The system pairs two CRNE 15-1 pumps in parallel duty, controlled as a single coordinated system.
- At P2 each main pump is 1.1 kW, covering the duty without oversizing the frame.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.
- Maximum operating pressure of 10 bar with motors sealed to IP55.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- 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.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- Variable speed comes from frequency converters matched to IE5 permanent magnet motors, keeping the booster set in its efficient range.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
