Backhoe loaders on the market run several different pump architectures depending on brand and model year — Rexroth's load-sensing A10VO is the most common, but the 90R075 is a genuine, documented alternative fitment on certain machines. The same displacement also fits Sauer Danfoss's excavator weight-class range at the 3-5 tonne mini excavator level, where it handles closed-circuit travel drive rather than the backhoe loader's combined loader/backhoe function.
90R075 — Confirmed Applications
| Application | Function | Notes |
|---|
| Backhoe Loader | Loader + backhoe combined circuit | Alternative to the more common Rexroth A10VO |
| Mini Excavator (3-5 tonne) | Closed-circuit travel drive | Separate from the main working-equipment pump |
Confirm your exact machine and application before ordering — WhatsApp a photo of your pump's nameplate for a precise match.
Confirm Your System First
Check your existing pump's nameplate for "Sauer Danfoss," "Sauer-Danfoss," or a model code starting with "90R" — this confirms Series 90 fitment rather than the more common Rexroth system. WhatsApp us a photo and we'll verify the exact match before quoting.

FAQs — Sauer Danfoss 90R075 Pump
Is my backhoe loader's pump really Sauer Danfoss — I thought it was usually Rexroth?
Rexroth's A10VO is indeed more common, but the 90R075 is a genuine, documented fitment on certain backhoe loader brands and model years. Check your pump's nameplate to confirm rather than assuming.
Is the backhoe loader version the same as the mini excavator version?
They share the same 75cc/rev Series 90 base pump, but the backhoe loader application drives a combined loader/backhoe circuit while the excavator application is dedicated to closed-circuit travel drive. Confirm your exact machine when ordering.
