Product Questions & Answers

Got a closed-circuit drive system on a piece of heavy construction equipment and trying to figure out if this pump'll work for it. Variable displacement, servo control, that what this is?

Question by: Howard C on Jul 6, 2025, 12:54 PM

Yeah, that's exactly what this is. The M39 is a variable displacement closed-circuit piston pump with servo control built in, so it's made for the kind of proportional response you need in a closed-circuit drive setup. Construction is one of the primary applications it was designed around, so that lines up well with what you're running.

Will this pump work alright in heavy equipment like a bulldozer or is it more for lighter duty stuff?

It's definitely built for heavy-duty service. The Danfoss / Eaton M39 Hi-Speed VAR.Pump is designed for demanding mobile environments like construction equipment, agriculture, and even oil and gas applications.
