Frequency drives (VFDs) are increasingly used in combination with pumps due to their ability to improve efficiency and performance. Thus reducing energy consumption. In this blog, we discuss the benefits of using VFDs with Hendor pumps and provide practical tips for their application.

What is a frequency drive?

A frequency drive, also known as a variable speed drive, controls the speed of an electric motor by adjusting the frequency of the power supply. This offers more control than traditional on/off switches, allowing the pump to operate more efficiently by adjusting the speed to match the actual flow demand.

Why Hendor pumps with frequency drives?

Hendor works exclusively with Kostal Industrial Electronics GmbH for motor-mounted frequency drive solutions, specifically the INVEOR M series. These drives have proven to be reliable and efficient in practical applications with Hendor pumps. They are supplied pre-installed and pre-programmed, ready for direct use, making them ideal for smart installations, Industry 4.0- and IoT-ready.

Benefits of using Hendor pumps with frequency drives

1.    Increased energy efficiency: Kostal's INVEOR M series provides an innovative control method that ensures optimal system efficiency. This results in significant energy savings, especially at partial loads.
2.    Lower maintenance costs: By reducing mechanical stress and excessive pressure, VFDs extend the lifespan of the pump and reduce the maintenance interval.
3.    Cost savings: In addition to energy savings, VFDs result in lower operational costs due to reduced wear and increased efficiency.
4.    Flexible and precise control: VFDs offer precise adjustment of the pump speed to match demand, which is essential in applications where flow requirements vary.
5.    Fewer system components: The use of VFDs can reduce the need for additional mechanical components such as valves and extra piping, simplifying and lowering the cost of installation.

Practical application and selection of frequency drives

When selecting the right frequency drive for a pump installation, there are several key factors to consider:
1.    Compatibility with the motor: Hendor pumps equipped with INVEOR M drives are compatible with various motor types and offer a wide range of application possibilities.
2.    Environmental resistance: The INVEOR M drives are designed to perform well in demanding environments with high temperatures and vibrations, making them suitable for both indoor and outdoor installations.
3.    Ease of use and programmability: Kostal’s modern VFDs offer intuitive control panels and advanced programming capabilities, such as integrated soft PLCs and fieldbus systems, simplifying installation and use.

Conclusion

Using frequency drives with Hendor pumps offers significant benefits in terms of energy efficiency, maintenance costs, and operational flexibility. The collaboration between Hendor and Kostal, with the INVEOR M series drives, provides a reliable and efficient solution for various pump installations. This combination allows users to benefit from both technical and economic advantages, resulting in sustainable and cost-effective operations.
