Product Questions & Answers (2)

Question by: Dwayne M on Feb 7, 2026, 2:49 PM

Running a closed circuit setup on a piece of construction equipment and need a variable displacement pump that can handle the workload. This the right kind of unit for that?

Answer by: Customer Support on Feb 8, 2026, 5:45 PM

Closed circuit piston pump applications in construction are exactly where this pump is built to operate. It's a heavy duty unit from Danfoss Power Solutions with variable displacement and servo control, so it adjusts output based on demand rather than running at a fixed rate. That makes it well suited for mobile equipment where loads shift constantly and efficiency matters. Agriculture, truck and bus, and oil and gas rigs are also listed applications, so it covers a pretty wide range of tough mobile environments.

Will this pump work on a tractor, or is it just for big rigs?

It's designed for mobile applications, so tractors and other agricultural equipment are definitely within its range, along with construction equipment, trucks, buses, and even oil and gas machinery.
