Product Questions & Answers

Will this pump work on my tractor, running implements?

Question by: Merle M on Jun 29, 2025, 8:37 PM

Designed for demanding mobile environments like construction and agriculture, this Danfoss/Eaton pump should be suitable for running implements on a tractor, given it's integrated into a closed-circuit hydraulic system.

Got a closed circuit mobile setup on a piece of construction equipment and need a variable displacement pump with clockwise rotation. This the right unit for that kind of application?

Question by: Lyle B on Feb 3, 2026, 6:47 AM

Clockwise rotation, variable displacement, closed circuit design built for mobile use, that's exactly what this pump is. The S2 39 is part of Danfoss Power Solutions' Series 2 platform and covers construction, agriculture, truck and bus, and oil and gas applications. If your system calls for CW rotation and you're running a demanding mobile duty cycle, this unit fits that profile well.
