Grundfos® CRE Pump

A winning combination
Efficient CR and variable speed motor are a perfect match
Many pump applications involve varying flows and pressures, calling for solutions that adapt themselves perfectly to all situations and provide the results you want. The Grundfos CRE range is designed to do just that, with remarkable efficiency. The CRE pumps represent the union of the well-known Grundfos CR – the most efficient and reliable multistage centrifugal pump on the market today – and variable-speed motors developed by Grundfos with optimum electronic control in mind.

The Benefits of the CRE
The CRE pump’s integrated frequency drive provides a wide range of unique benefits:

• Energy consumption reduced by up to half compared to fixed speed pumps
• Remote control/fieldbus monitoring and data collection
• Reduced system wear
• Integrated sensor available
• Easy installation and operation — settings and internal connections done at factory
• Full range of pumps for all applications
• Superior user comfort

Efficiency and comfort
Substantial energy savings
Variable speed brings constant benefits. CRE pumps adjust their speed to exactly suit current demands, meaning energy is never wasted on generating pressure you don’t require. The result is energy savings of up to 50% – year in and year out.

Perfect precision
Carefully controlled processes
Maintaining constant water pressure is just one of the many things that the CRE pumps can do with complete precision. Their adaptability enables them to deliver the exact flow and pressure required for almost any media and in almost any situation. Do you need constant differential pressure? Stable pH levels? Specific temperatures? Carefully timed operation? The CRE pumps can give you all of this and much more.

A range of smart pumps
Grundfos offers a wide range of “E-pumps” with variable speed motors and integrated control features. The range includes pumps for almost any conceivable application. An E-pump can improve the life cycle costs of the system, whether it’s for heating, air conditioning, water supply, pressure boosting, or processing systems in an industrial plant.

Grundfos E-pumps help streamline ordering and maintenance since the pump, motor with variable frequency drive, connections, and accessories come from one supplier.
