Product Overview
Residential towers and medium commercial sites outgrowing their mains pressure get a constant-pressure answer in this Grundfos Hydro Multi-E 2 CRNE 10-6 set. Everything is ordered under the single part number 99752292.
This set provides up to 498 L/min of flow capacity. Variable-speed operation can develop up to 87 metres of head where required. There is no separate central controller to purchase: Multi-Master control resides within the pumps, either unit can assume the controlling role, and a fault is handed over cleanly without interrupting supply.
For installation, the booster is supplied pre-assembled with stainless steel manifolds, two 50 mm manifold connections, isolation valves, non-return valves, pressure sensors and a gauge, plus a 24L diaphragm tank. It is designed for 3 x 380-415 V power at 50 / 60 Hz with a rated current of 12.4 A, with IP55 motor protection and a 10 bar maximum system pressure. Liquid-temperature suitability is 5°C to 60°C. Inlet pressure is rated to 10 bar.
Applications include industrial process supply, mixed-use commercial buildings and high-rise apartments. The control flexibility suits clean-water boosting in new installations and upgrades.
Features
- Two Grundfos CRNE 10-6 pumps share the boosting work in parallel.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- The package is wet-tested and pre-configured, requiring only pipework and power on site.
- Stainless steel manifolds provide two 50 mm manifold connections ready for pipework.
- At P2 each main pump is 3 kW, covering the duty without oversizing the frame.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- The system protects its pumps against dry running if the incoming supply is lost.
- Cascade logic brings pumps on-line and off-line against changing demand without manual intervention.
- Constant pressure control holds the delivered pressure flat while proportional mode lets setpoints flex with demand.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a phone.
- Rated for 10 bar system pressure; motors carry IP55 protection.
- The set ships with an 24L precharged diaphragm tank for low-flow stability.
