Product Overview
The WHITE OMP X 250 (Part Number: 11185798) is a high-performance hydraulic orbital motor engineered by WHITE Hydraulics, a recognized brand in the mobile and industrial hydraulics sector. This motor operates on the gerotor/geroller orbital principle, where pressurized hydraulic fluid acts on an internal gear set to generate smooth, high-torque rotary output directly at the shaft. The OMP series is specifically designed as a compact, cost-effective solution for medium-duty applications requiring reliable starting torque and consistent low-speed performance. With a displacement of 250 cm³/rev, this model delivers substantial torque at relatively low flow rates, making it an ideal prime mover for conveyor drives, winches, augers, and rotary brush systems in industrial and mobile equipment.
