Product Overview
Aged-care residential communities requiring sensitive, scald-free pressure stability select the Hydro Multi-E 2 CRNE 32-1-1. The two-pump parallel layout shares duty evenly across the CRNE 32-1-1 wet ends, preserving steady pressure during morning spikes. Quote part number 93368407 to have the entire pre-commissioned assembly delivered to site.
The booster easily handles flow rates up to 1600 L/min across peak hours. Up to 21.5 metres of shut-off head is generated to overcome vertical riser friction. 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.
Fabricated on an engineered steel base frame, the booster incorporates stainless steel pipework, 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 11.3 A (2 x 5.65 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.
Frequently installed across hospital surgical wings, aged-care complexes and industrial process supply, the package handles wide demand swings with ease. Variable-speed motor modulation makes the set a practical clean-water pressure-boosting solution for both new plant rooms and system upgrades.
FEATURES
- The system pairs two CRNE 32-1-1 pumps in parallel duty, controlled as a single coordinated system.
- Stainless steel manifolds provide two 100 mm manifold connections ready for plant pipework.
- Pumps are cut in and out according to demand, every running unit turning at the same speed to hold the pressure set point.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Maximum operating pressure of 10 bar with motors sealed to IP54.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- At P2 each main pump is 1.5 kW, covering the duty without oversizing the frame.
- Multi-Master redundancy means either pump can act as controller, with seamless changeover on fault.
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
- The system protects its pumps against dry running if the incoming supply is lost.
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- Integrated Grundfos GO compatibility supports configuration, logging and diagnostics from a smartphone.
- Each pump is driven by IE5 permanent magnet motors with frequency-controlled speed matching demand.
