Question by: Floyd C on Sep 28, 2025, 6:25 AM
Running a crawler dozer and need a new pump, this X20 420 series got the displacement I'm looking for, but does it actually hold up in heavy-duty cycles like mining or tunnel work?
Answer by: Customer Support on Sep 29, 2025, 3:55 PM
Built for exactly that kind of punishment. The X20 420 series is rated for mining machinery, tunnel boring equipment, and crawler dozers, so it's not just tolerating those environments, it was spec'd with them in mind. The high pressure and flow capacity means it can handle demanding hydraulic loads without backing down, and the fast response and recovery times help keep output consistent even when the work gets ugly. For open circuit piston pump applications in continuous heavy-use cycles, this is a solid fit.
