DANFOSS / EATON-S2 39 (3.3) VARIABLEPUMP CW

Description & Features

Designed for demanding mobile hydraulic applications, the Danfoss / Eaton S2 39 (3.3) Variable Pump CW is a closed-circuit, variable displacement piston pump built to perform reliably across construction, agriculture, truck and bus, oil and gas, and other mobile environments. Its closed-circuit architecture makes it well-suited for hydrostatic drive systems where precise flow and pressure control are required.

The pump supports multiple control options, giving system designers flexibility in how output is managed. Pro-FX ready compatibility allows integration with Danfoss Power Solutions' electronic control platform, supporting more advanced machine control strategies. Clockwise rotation is standard for this configuration.

Question by: Darryl C on May 11, 2025, 9:23 AM
We run a hydrostatic drive setup on one of our ag machines and been looking at variable displacement pumps to replace what we got now. This one work for closed-circuit systems?
Answer by: Customer Support on May 13, 2025, 6:32 AM
Closed-circuit operation is exactly what this pump is built around. The S2 39 is a variable displacement piston pump configured specifically for closed-circuit hydrostatic drive systems, so flow and pressure can be managed with a good bit of precision. It covers construction, agriculture, truck and bus, and oil and gas applications, so farm equipment falls right in line with its intended use.
