Certified Company ISO 9001-2008



Discover new levels of efficiency with the Grundfos CRE pumps, designed with built-in control modes and optimised functions to manage various industrial applications.


Vertical, multistage centrifugal pump with integrated frequency converter. The pump head and base are in cast iron – all other wetted parts are in stainless steel (EN 1.4301)

Suitable for:

  • Commercial fire protection
  • Bottle washing
  • Filling
  • Leach mining
  • Industrial fire protection
  • Industrial water supply
  • Water reuse
  • Surface water intake


Take control with variable speed

The CRE is a multi-purpose in-line multi-stage pump with a built-in variable-speed drive available in a wide variety of flow and pressure sizes and is built from AISI 304 grade stainless steel/cast iron. The variable-speed drive continually adapts pump performance to match current conditions and desired pressure, temperature or flow. This makes the CRE perfect for a variety of applications including water supply, washing and cleaning, water treatment, boiler feed, chemical industries, temperature control and mining.

Extended input and output options

The CRE pump offers a variety of configurable input and output options, including:
• Three analogue inputs (0-10 V;  0/4-20 mA;  0.5-3.5 V)
• One analogue output (0-10 V; 0/4-20 mA)
• Two dedicated digital inputs
• Two configurable digital inputs or open-collector outputs
• Two Pt100/1000 inputs for temperature measurement
• LiqTec sensor inputs – dry-running protection sensor
• Two signal relay outputs
• GENIbus connection
• Interface for CIM field bus modules

Extended specifications

Ambient temperature: Full load continuous 50°C, maximum allowed 60°C

Enclosure class: IP55 and IP66

Maximum speed: 5900 rpm

Wide supply voltage: Single-phase: 200-240 V Three-phase: 380-500 V


Extended communication

As part of the intelligent iSOLUTIONS programme the CRE pumps allow a variety of Communication Interface Modules (CIM) to be built into the pump to enable communication with and data transfer to SCADA and BMS systems.

Industrial Ethernet
The CRE pump supports a number of industrial Ethernet standards, by the use of extension modules. As a result, installation is made easier and the initial cost lower because the pump can be integrated directly into BMS and SCADA systems. The following industrial Ethernet standards are currently supported:
• Modbus TCP
• BACnet/IP

Serial fieldbusses
The CRE pump has options for CIM extension modules supporting the following serial based communication standards:
• Modbus RTU
• BACnet MS/TP
The CRE pump is equipped with a Grundfos GENIbus interface.GSM
The GSM module enables remote data transmission from Grundfos pumps or controllers – via mobile phones or SCADA systems.GRM
Grundfos Remote Management makes it possible to monitor and manage pump systems remotely to reduce the need for costly – and often unnecessary – on-site inspections.

MGE motors for increased efficiency and control

Available with the IE5 MGE motor, which delivers the highest levels of energy-efficiency in the market and matches pump speed to constantly-changing requirements, giving you full control.

Pump performance can be continually monitored so that you are alerted when it no longer meets your expectations.

Optimal motor utilisation. The standard product range is optimised for maximum utilisation of the motor’s power output.

Grundfos GO
Grundfos GO is the industry’s most advanced mobile pump control solution, designed to be totally compatible with all Grundfos E-pumps, including the CRE. The intuitive device allows you to become the commander of your entire pump fleet – all from the palm of your hand.
