Product Overview

The SUNNY 25V10A-1A22R is a precision-engineered hydraulic vane pump from the SUNNY (Yuken-style) 25V series, designed for dependable medium-pressure industrial hydraulic power generation. Utilizing a balanced vane rotor and cam ring working principle, this fixed-displacement pump delivers smooth, low-pulsation flow suitable for continuous-duty circuits. The 25V10A designation indicates a nominal displacement of 10 US gpm (approximately 38 L/min at 1200 rpm), while the “A” suffix denotes the standard pressure rating configuration. The 1A22R mounting and porting code provides a SAE-compatible flange and side-port arrangement for straightforward integration into existing power units, manifolds, and OEM hydraulic systems. Its cartridge-style construction allows rapid field service and interchangeability with equivalent 25V-series vane pumps.
