Hydraulic Pump Parts Charge pump 90R250 47cc/65cc

This charge pump is a critical OEM component designed for the Danfoss 90R250 axial piston pump, a staple in heavy-duty closed-circuit hydraulic systems. It serves as the integral replenishing unit, ensuring consistent pressure and flow for system stability.

Available in 47cc and 65cc displacements, it matches the 90R250 pump’s performance requirements precisely. The 47cc variant suits standard-duty operations, while the 65cc version delivers higher flow for extreme load conditions, covering diverse application needs.

Built with high-grade carbon steel and precision-machined gears, this charge pump offers exceptional durability. Its robust construction resists wear, corrosion, and high-pressure shocks, maintaining reliable operation even in harsh environments like construction sites and mines.

It functions to replenish internal leakage, maintain positive main circuit pressure, and supply oil for cooling, filtration, and control systems. This prevents cavitation and overheating, extending the main pump’s service life and reducing downtime.

Fully interchangeable with the original 90R250 charge pump, it enables direct replacement without modifications. Rigorously tested to OEM specifications, it ensures seamless compatibility and consistent performance, making it an ideal choice for repair and maintenance.
