By using a Variable Frequency Drive (VFD) control system with these pumps, you can enjoy the benefits of enhanced control and reduced energy costs. With the ability to precisely control the output, VFDs provide greater flexibility for meeting the needs of your application, making them the perfect choice for any business. DNOW can offer the ideal combination of positive displacement pumps and VFD control systems to ensure you receive the best performance possible.
Reliable and Consistent PerformancePositive displacement pumps can move fluid consistently, regardless of pressure fluctuations or changes in the amount of fluid being moved. They offer reliable, consistent performance and are often used in applications such as chemical processing, oil and gas production and water treatment. Additionally, the pumps are designed to provide a steady stream of liquid for various applications. They can be outfitted with adjustable speed, pressure protection, and enhanced safety features.
