Eaton’s Hydraulics Group has announced a new variable speed drive (VSD) pump solution that can provide up to 70% energy savings for equipment in the machine building, manufacturing, oil and gas and marine industries, depending on the machine duty cycle. The industrial pump solution, available in open- or closed-loop motion control configurations, reduces operational costs by allowing quieter machine operation, reducing or eliminating cooling needs and allowing for pump downsizing.
The solution can include one or more pumps, selected from an offering of PVM variable piston pumps, Hydrokraft variable piston pumps or VMQ fixed vane pumps. Together with the smart control of variable speed drives, the system can be controlled to match the precise load requirements of the current duty cycle.
“Energy consumption plays a significant role in overall machine operating costs, and as energy costs increase, Eaton has worked to provide more efficient solutions without sacrificing safety or power,” said Wayne Wang, product strategy and planning manager, Industrial Product Portfolio, Eaton’s Hydraulics Group. “By combining the proven reliability and availability of Eaton’s Hydraulic and Electrical solutions, we are helping enable more sustainable, cost-effective industrial operations.”
Running pumps at a variable speed also reduces noise pollution, protecting operators hearing while meeting noise regulations. As equipment efficiency increases, oil coolers can be downsized, limiting the amount of oil used and extending the life of seals and oil.
