Product Overview
Sites such as mixed-use buildings where a single booster covers retail, offices and apartments require consistent pressure regardless of demand fluctuation; the Hydro Multi-E 2 CRNE 10-2 achieves this with two CRNE 10-2 pumps operating in parallel. Everything is ordered under the single part number 99752278.
This set provides up to 504 L/min of flow capacity. Variable-speed operation can develop up to 28 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.
The two-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 12.9 A. The motors have IP55 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.
Applications include aged-care complexes, hotel plant rooms and industrial process supply. The control flexibility suits clean-water boosting in new installations and upgrades.
Features
- Two Grundfos CRNE 10-2 pumps share the boosting work in parallel.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- Rated for 10 bar system pressure; motors carry IP55 protection.
- The system protects its pumps against dry running if the incoming supply is lost.
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- Slow-speed duty and staged switching keep consumption down through low-demand hours.
- Setup and monitoring run through the Grundfos GO app rather than a panel visit.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Each main pump is rated 1.1 kW (P2), so per-pump draw scales down as speed follows demand.
- Stainless steel manifolds provide two 50 mm manifold connections ready for pipework.
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.
