Product Questions & Answers

Will this work on a construction excavator?

Question by: Billy J on Jan 24, 2026, 6:11 AM

Application-wise, it's definitely used in construction equipment, along with agriculture, trucks, buses, and even some oil and gas applications. So yeah, should fit the bill for an excavator.

Running a closed circuit setup on a track loader and been burned before by pumps that couldn't keep up with the duty cycles we throw at em. This a Series 2 platform from Danfoss or something older?

Built on the Danfoss Power Solutions Series 2 platform, which has a solid track record in heavy mobile applications. The S2 39 is a variable displacement piston pump, so output adjusts to match load demand rather than running at a fixed rate. That characteristic alone makes it a better fit for equipment that sees varied and demanding duty cycles, like a track loader would. The closed circuit architecture is part of what makes it practical for that kind of work.
