Yuken is a genuinely well-established Japanese hydraulics manufacturer, and its A-series and quieter AR-series variable displacement piston pumps (AR16 at 15.8 cc/rev, AR22 at 22.2 cc/rev, and larger variants) are widely used across stationary hydraulic power units — think injection-molding machines, industrial presses, and factory equipment — rather than as a primary main pump on excavators or cranes the way Kawasaki or Rexroth pumps are.
Where we genuinely see Yuken demand from mobile-equipment customers is in hydraulic power packs mounted on trucks or trailers, and some mobile machinery with stationary-style hydraulic circuits. If that's your use case, we can help — but we want to be upfront that this isn't a core excavator/crane brand for us the way our other listed brands are.
Looking for an Excavator or Crane Pump Instead?
If your machine is an excavator, crane, forklift, or similar mobile equipment, it's very unlikely to run a Yuken main pump — check out our Which Pump Do I Need tool or WhatsApp your machine details and we'll point you to the right brand.
