Question by: Brett K on Jan 30, 2026, 6:15 AM

Running a closed circuit setup on a skid steer loader and need something that can handle variable flow demands without constant manual adjustment. This pump rated for that kind of work?

Answer by: Customer Support on Feb 1, 2026, 6:40 AM

Variable displacement is exactly what handles that situation well. The M39 is built for closed circuit mobile applications and supports multiple control options, so flow can be managed dynamically based on drive system demand rather than running at a fixed output. Construction equipment is one of the core applications it's designed around, so a skid steer loader falls right in line with its intended use.
