Product Overview
The WHITE OMP X 400 (Part Number: 11186714) is a high-performance hydraulic orbital motor engineered by White Drive Products, a globally recognized brand in the mobile and industrial hydraulics sector. Operating on the proven gerotor/geroller orbital principle, this motor converts hydraulic pressure and flow into reliable rotational torque through an internal gear set and a cardan shaft drive mechanism. The OMP X series is specifically designed for medium-duty applications where compact size, smooth low-speed operation, and consistent torque output are critical. With a displacement of 400 cc/rev, this motor delivers substantial torque at relatively low input flows, making it an ideal solution for direct-drive and auxiliary circuit applications in industrial machinery and mobile equipment.
