Got an 80cc open circuit piston pump that needs replacing on a loader backhoe, this the right size and setup for that kind of machine?

Answer by: Customer Support on Feb 9, 2026, 9:28 PM

Loader backhoes are one of the primary applications this pump was built for. At 4.88 cubic inches of displacement (80cc) and rated for high pressure and flow, it fits right in with the demands that kind of equipment puts on a hydraulic system. The 420 series Code B configuration is part of the Danfoss X20 open circuit lineup, so as long as your system runs an open circuit architecture, you're in good shape on that front.
