AA10VO60DFR/52R-VWD61N00

The AA10VO60DFR/52R-VWD61N00 pump is part of the A10VSO Variable Pumps series from Bosch Rexroth, intended to deliver adjustable axial-piston flow in hydraulic automation circuits. It installs with an ISO 3019-1 two-hole C flange, so machine builders can fasten the housing directly to standard bell housings. Rear port orientation code 61 places the suction and pressure connections on the back face to streamline straight-line piping. Flow is directed through SAE flanges in accordance with ISO 6162, providing a leak-resistant joint for high-pressure lines. The rotating group turns clockwise, matching right-hand prime movers without additional adapters. Continuous service is supported at a nominal pressure of 4,100 psi, while brief pressure spikes up to 5,100 psi can be accepted by the pump body. A DFR control keeps standby pressure 200 psi above load to guarantee rapid response when demand rises. Positive inlet conditions are maintained by requiring at least 12 psi absolute to the charge port, protecting the pistons from cavitation.

The internal pressure compensator is set to 4,100 psi, mirroring the nominal rating and allowing the pump to reduce displacement once that level is reached. An auxiliary pilot port X tolerates the same 5,100 psi maximum, so external control signals can be routed without separate relief devices. The case can withstand 30 psi absolute, letting return oil pass through common drain circuits without breaching shaft seals. Mineral-based HLP fluid conforming to DIN 51524-2 is specified for lubrication and damping, and the hydraulic cleanliness must be at least ISO 4406 class 20/18/15 to limit abrasive wear. High-temperature service is accommodated by FKM seals that resist degradation in aggressive oil additives. There is no through-drive option on this configuration, identified by code N00, which confines power transmission to a single pump and removes alignment tasks for tandem units. Together these parameters define installation limits, fluid requirements, and control interfaces so the pump can operate reliably in mobile or industrial actuation systems.
