Question by: Brenda F on Jan 8, 2026, 9:51 AM

What kind of equipment is the S2 39 variable pump actually built for? Got a mixed fleet and trying to figure out if this fits more than one machine.

Answer by: Customer Support on Jan 9, 2026, 12:53 PM

Construction equipment, ag machinery, trucks, buses, and oil and gas rigs all fall within the intended range for this pump. It runs a closed circuit piston design, which means it handles variable load conditions well without sacrificing flow control. If your fleet covers any of those categories, this pump was built with that kind of work in mind.

Reckon this would hold up okay in a construction environment, dealing with all the dust and whatnot?
