Product Overview

The Sauer Danfoss 90R250 KA1BC80 T4F1 J03 NNN is a high-performance axial piston pump from the renowned 90 Series, engineered for demanding closed-loop hydrostatic transmission systems. Utilizing a robust swashplate design with axial pistons and a bent-axis rotating group, this pump delivers exceptional pressure capability, precise displacement control, and high overall efficiency. The 90R250 is a variable displacement unit with a nominal displacement of 250 cm³/rev, designed to serve as the primary pump in closed-circuit applications where smooth, bidirectional control of hydraulic motors is required. Its advanced servo-controlled displacement mechanism enables infinite adjustment of flow output, making it ideal for heavy-duty industrial and mobile hydraulic systems that demand reliability, responsiveness, and long service life.
