Product Questions & Answers

Got a mini excavator that's been eating through pumps, and I'm tryin to figure out if this 80cc unit from the 420 Series would hold up to that kind of workload. These machines run hard all day on a job site.

Heavy daily use on excavators is exactly what this pump line was built around. The 420 Series covers mini excavators right alongside crawler dozers and articulated haulers, so the engineering accounts for that kind of sustained, high-demand cycle. The high pressure and flow capacity ratings back that up in practical terms. If your current pump has been struggling under constant load, the response and recovery characteristics on this unit are specifically noted as among the fastest available, which helps a lot when hydraulic demand spikes and drops repeatedly throughout a shift.
