Question by: Duane H on Nov 9, 2025, 7:26 PM

Got a loader backhoe that needs a new pump and I keep seeing this X20 series come up in searches. Is this the right family of pumps for that kind of machine?

Answer by: Customer Support on Nov 11, 2025, 8:30 AM

Loader backhoes are one of the primary applications this pump was built around, so yes, you're looking in the right place. The X20 series handles high pressure and high flow demands, which is exactly what that type of machine puts on a pump. The 4.88 CID displacement puts it in a solid range for that work, and the fast response and recovery times help when you're cycling loads repeatedly throughout the day.
