Product Overview
Across installations such as tea rooms, staff kitchens and en-suite banks in small commercial sites, the Hydro Multi-E 2 CRE 3-8 maintains stable pressure at every draw-off point. The complete system ships factory assembled and tested under part number 99614267.
It handles flows up to 159 L/min across the system. The pumps can develop up to 74 metres of head when pressure demand increases. Because every pump carries its own frequency converter and the Multi-Master software elects the controlling pump itself, losing a control unit or pressure sensor means seamless handover rather than a shutdown.
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 3 x 380-415 V at 50 / 60 Hz with a rated current of 3.7 A. The motors have IP54 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 mixed-use commercial buildings, industrial process supply and schools and universities. The control flexibility suits clean-water boosting in new installations and upgrades.
Features
- Power use precisely tracks demand, avoiding the waste of fixed-speed alternates.
- Rated for 10 bar system pressure; motors carry IP54 protection.
- 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.
- The controller tracks the pressure setpoint with proportional deviation alerts before conditions become faults.
- An integrated 24L diaphragm tank carries small draw-offs and limits pump cycling.
- Setup and monitoring run through the Grundfos GO app rather than a panel visit.
- Pump staging follows demand automatically: pumps enter at low speed as pressure drops, ramp to equal speed, and exit as flow fades.
- Each main pump is rated 0.75 kW (P2), so per-pump draw scales down as speed follows demand.
- No external controller required: Multi-Master redundancy lets either pump assume the controlling role.
- Factory assembled and wet-tested, the set arrives pre-configured for straightforward installation.
- The system pairs two CRE 3-8 pumps in parallel duty, controlled as a single coordinated system.
- Stainless steel manifolds provide two 50 mm manifold connections ready for pipework.

How much discharge water volume can this parallel booster assembly supply during peak periods?
Operating across its factory curve, the Grundfos Hydro Multi-E 2 CRE 3-8 U2 A-A-I-I-DU discharges up to 159 L/min of clean water to maintain consistent line pressure during peak demand cycles.
How are the multistage pumps driven and electronically regulated across fluctuating demand?
Each centrifugal stage of the Hydro Multi-E 2 CRE 3-8 is driven by a 0.75 kW IE5 permanent-magnet MGE electric motor running on 3 x 380-415 V power, utilizing built-in variable speed drives to adjust output dynamically.
What maximum discharge head and system pressure does this parallel centrifugal skid maintain?
Elevating water across multi-level pipework, the Hydro-Multi-E-2-CRE-3-8 maintains up to 74 m total dynamic head with an overall 10 bar maximum operating limit.
Which inlet and outlet pipe connection fittings are factory supplied on this booster package?
Plumbed for rapid site installation, the Hydro Multi E 2 CRE 3 8 includes R 2 stainless steel headers equipped with dedicated isolating valves, check valves, and pressure transmitters.
Which factory warranty terms protect this complete multi pump booster package?
Grundfos provides two-year manufacturer warranty coverage on the 2 CRE 3-8 (Hydro Multi-E), securing the complete multi-pump package, manifolds, and integrated electronics.
