SGA-150

The Bruce SGA-150 is a precision rotary-head designed for heavy-duty drilling operations requiring consistent torque delivery and variable speed control. Engineered for foundation engineering and deep borehole applications, this rotary head combines robust motor technology with reliable pressure regulation to achieve optimal performance in challenging soil conditions. With its dual-displacement motor configuration, the SGA-150 delivers professional-grade drilling capabilities that meet the demanding requirements of modern geotechnical projects. Bruce SGA-150 specifications reflect industry-leading engineering standards, featuring a motor displacement of 170×2 cc/rev that enables flexible operational speeds ranging from zero to 23 rpm. This variable-speed design allows operators to precisely adjust drilling parameters based on soil composition and depth requirements. The unit generates a maximum output torque of 8 ton·m, providing the rotational force necessary for efficient penetration and stable borehole development. Optimized for demanding downhole environments, the Bruce SGA-150 rotary-head operates at a required pressure of 300 bar, ensuring stable and predictable performance throughout extended drilling campaigns. This pressure specification makes it compatible with standard hydraulic systems, reducing equipment integration costs while maintaining superior drilling efficiency. The combination of displacement, torque capacity, and pressure ratings positions the SGA-150 as an essential component for contractors requiring dependable rotary drilling equipment.
