Cat® Piston and Gear Pumps and Motors are designed, manufactured and tested to meet the unique performance requirements of Caterpillar equipment models they are used in. This ensures they achieve the specific machine performance, reliability, durability, operating costs and productivity requirements.

Advanced electronic controls let you switch dynamically among three distinct control modes: load sense, pressure control, and displacement / flow control -all while managing engine underspeed control.
