Product Questions & Answers

Got a mini excavator that's been eating through pumps and I'm trying to figure out if this one's built for that kind of punishment. It's an open circuit system. Will this 80cc unit hold up to variable load conditions on that kind of machine?

Question by: Ross R on Sep 10, 2025, 8:02 AM

Mini excavators are actually one of the listed applications for this pump, so you're in the right place. The 420 Series is built for mobile hydraulic work where loads shift constantly, and the fast response and recovery characteristics are specifically what make it useful in those situations. Open circuit piston design handles variable demand better than gear pumps in most cases, so for an excavator that's cycling through different attachments or working tough material, this setup should give you more consistent output than what you may have been running before.

Will this Eaton pump work okay on my older tractor? It's got a loader on it.

This open circuit piston pump is often used on agricultural tractors, especially those with loader attachments. Its fast response time can really help with loader operation.
