The VH023525S081067A0DB00AAADHAAR000022 unit belongs to the Piston Pumps series and is manufactured by Vickers for hydraulic automation tasks such as supplying pressurized fluid to actuators. The front pumping element has a displacement of 81 cm³ per revolution, setting the flow volume delivered on each shaft turn, while the rear element is rated at 67.6 cm³ per revolution to serve an auxiliary circuit with a smaller output. A VHO2 frame size defines the mounting envelope and aligns the housing with standardized drive flanges. Right-hand shaft rotation specifies the direction of drive torque and must match the prime mover. The housing is cast iron, a material chosen for pressure containment and vibration damping. A single shaft seal limits leakage along the drive end, and Buna-N seal material resists common petroleum-based hydraulic oils while retaining flexibility.
Connection details start with the front outlet port, located 90° clockwise from the inlet, which supports compact pipe routing. That port follows the SAE J518C four-bolt English pattern so standard SAE four-bolt flanges can be installed without adapters. The rear outlet terminates 135° clockwise from the inlet, giving designers a staggered path that avoids hose interference between stages. Overall height is 8.5 in, length is 15.93 in, and width is 10.44 in, dimensions that aid clearance checks when the pump is placed between motor and tank inside a power unit. The 97 lb mass contributes to stability on mounting brackets and reflects the thick-walled casting needed for continuous service.
