Question by: Lee T on Mar 25, 2026, 8:01 PM
Got a loader backhoe that's been eating through pumps and I'm trying to step up to something that'll actually hold up. This the right pump for that kind of machine?
Answer by: Customer Support on Mar 27, 2026, 8:28 AM
Loader backhoes are one of the primary applications this pump was built around, so yeah, you're on the right track. The 420 Series X20 open circuit piston pump handles high pressure and high flow demands, which is exactly what a backhoe puts on a hydraulic system. The 3.00 CID displacement gives it solid output capacity, and the advanced control options help the system respond quickly when you're cycling through functions fast. For a machine that's been hard on pumps, moving to a piston pump design with faster response and recovery times can make a real difference in how the system holds up under repeated load cycles.
