Got a loader backhoe that needs a new pump and I keep seeing this 420 Series come up. What kind of work is this thing actually built for?

Answer by: Customer Support on Mar 25, 2026, 1:30 PM

Heavy equipment like loader backhoes is exactly where this pump earns its keep. The 420 Series also sees regular use in mining machinery, agriculture tractors, dump truck lifts, crawler dozers, and even concrete and asphalt pavers. It's an open circuit piston pump, so it's built for mobile hydraulic systems that deal with high pressure and demanding flow requirements day in and day out. If your backhoe is running a standard open circuit setup, this pump covers the kind of workload those machines put out.
