The High Flow (HF) Series represents the next-generation of high-horsepower, continuous-duty frac pumps engineered for superior performance, durability, and operational efficiency. Featuring a long stroke design, the HF Series delivers greater fluid displacement per revolution, reducing fatigue cycles and thermal load while extending service life.
Built on a robust new frame and equipped with a customizable smart gearing system, the HF Series empowers you to choose between two optimized configurations: the GD 5000HF and GD 3600HF. Each is precisely matched to operate at peak efficiency with electric, turbine, diesel, natural gas, or dual fuel power sources.
All that performance delivered in the lightest pump package in its class, weighing up to 4,000 lbs less than comparable models – delivering easier transport, improved trailer dynamics and measurable fuel savings.

The HF Series efficiently transfers available horsepower through to the fluid end, ensuring optimal flow performance and reduced mechanical strain across the entire pump system.

From power transfer to fluid delivery, every element of the HF Series works together to maximize uptime, efficiency, and reliability in the harshest frac environments.
For more than a century, GD Energy Products has set the standard for reliability in the field. The HF Series continues that legacy with engineering precision, proven durability, and simplified service that deliver lasting value across every operation. Performance you can trust. Support you can count on.
