HYDRO MULTI-E 3 CRE 15-8

GRUNDFOS Hydro Multi-E booster sets are designed for the transfer and pressure boosting of clean 

water in waterworks, blocks of flats, hotels, industry, hospitals, schools, etc. GRUNDFOS Hydro 

Multi-E booster sets consists of 2 to 3 CR(N)E pumps coupled in parallel and mounted on a common 

base frame provided with all the necessary fittings.

Hydro Multi-E is mounted on a common base frame made in stainless steel. On the suction side are 

fitted a suction manifold (EN 1.4301/ AISI 304) and two pressure transmitters which are mounted on 

an isolating valve. On the discharge side of the pumps are fitted a non-return valve, an isolating 

valve, a pressure gauge, two pressure transmitters mounted on an isolating valve, a diaphragm tank 

and a stainless steel discharge manifold (EN 1.4301/ AISI 304). The Hydro Multi-E is fitted with an 

on/off-switch for the supply voltage.

The Hydro Multi-E is designed for maintaining a constant pressure regardless of flow changes and 

fluctuation.

The internal PI-controller regulates the number of running pumps and the speed of the pumps according 

to the required flow.

The system can be operated directly on the graphical display of any of the pumps or via Grundfos GO 

(available as accessory).

Besides the system features:

2 Relay outputs

2 Digital inputs (one used for external start/stop)

2 Digital configurable input/output

3 analogue inputs (one used for discharge pressure and one used for inlet pressure)

Multi-Master functionality

2 Limit exceed functions (one used for dry running protection)

Set-point influence

Pipe filling function

Proportional pressure and High Efficient PM motors

Available communication protocols:

LON

PROFIBUS DP

PROFIBUS IO

BACnet MS/TP

BACnet IP

Modbus RTU

Modbus TCP

Ethernet IP

Cellular 3G/4G

GiC/GRM

When delivered, the GRUNDFOS Hydro Multi-E booster set is factory tested and ready for operation.
