The 25VQ12A 11C2025 hydraulic motor belongs to the Hydraulic Motors series produced by Vickers for automated fluid-power drives. It offers a displacement of 40.2 cm³ per revolution, delivering 12 gpm at 1200 rpm when supplied at 7 bar. Continuous operation is supported up to 210 bar (3000 psi), allowing consistent torque under load. Shaft rotation viewed from the drive end is right-hand clockwise, and peak speed reaches 2700 rpm for high-cycle machinery. Output torque is transmitted through a 0.875 in shaft that carries a 13-tooth 16/32 DP spline, giving a secure mechanical interface for couplings and gearboxes.
Hydraulic fluid enters through a 1-1/2 in SAE four-bolt flange inlet and exits a 1 in SAE four-bolt flange outlet that is positioned in line with the inlet to simplify piping. Installation uses an SAE-B two-bolt mounting flange, with a bolt span of 146.1 mm that matches standard pump pads. A 101.6 mm pilot diameter centers the housing, controlling radial runout between motor and driven equipment. These interface dimensions provide rigid support, maintain seal compression, and enable quick replacement within automated hydraulic systems.
