A10VO Series 52 pumps

Series 52 is the lightweight medium-pressure generation of the A10VO family. Swashplate design, open circuit — nominal pressure 250 bar, maximum 315 bar. It covers sizes NG10, 28, 45, 60 and 85, including the small NG10 and NG60 that Series 53 does not offer, and keeps the classic DFR / DFR1 load-sensing control naming. Available pumps are new aftermarket replacements, quality checked before shipping.

What is Series 52 used for?

Series 52 suits machines with medium pressure requirements where light weight and compact size matter. It is also the direct match when the original pump carries /52 in its model code — mounting, ports and the DFR/DFR1 control naming follow the original, with no code translation needed.
