A10VO Series 53 pumps

Series 53 is the extended medium-pressure generation of the A10VO family, covering sizes NG18 to NG100. Swashplate design, open circuit — nominal pressure 250 bar, maximum 315 bar. It builds on Series 52 and extends it: sizes NG18, 63, 72 and 100 are exclusive to this series, controls use the DRF / DRS naming, and constant-power LA plus electro-proportional EP/EK controls are available. Available pumps are new aftermarket replacements, quality checked before shipping.

What is Series 53 used for?

Series 53 suits machines with medium pressure requirements that need a wider size coverage or power / electro-proportional control. Sizes NG18, 63, 72 and 100 are exclusive to Series 53; the constant-power LA family suits winch and heavy-load circuits, while EP/EK electro-proportional controls suit applications needing precise remote swivel-angle setting. It is also the direct match when the original pump carries /53 in its model code — mounting, ports and the DRF/DRS control naming follow the original.
