Product Questions & Answers

What's this servo piston subassembly actually made of, and is it gonna hold up in a hard-working pump setup?

Question by: Sherry A on Mar 18, 2026, 4:56 PM

Steel construction throughout, so it's built to take the kind of stress that shows up in demanding hydraulic systems. Piston components in these pump assemblies deal with constant pressure cycling, and having a solid steel part in there matters a lot for keeping things running without premature wear.
