Hydraulic Pump Parts Charge pump 90R130 26cc/34cc/41cc

This charge pump is a core auxiliary component designed for the Sauer Danfoss 90R130 series axial piston pumps, serving closed-circuit hydraulic systems reliably. It comes in three displacement options: 26cc, 34cc and 41cc, to match different flow and pressure demands of 90R130 pump configurations.

Built with high-grade carbon steel and precision-machined components, this charge pump delivers consistent performance and long service life. The spline shaft and gear assembly are heat-treated for wear resistance, minimizing internal leakage even under continuous heavy loads. Each unit undergoes strict factory testing to ensure dimensional accuracy and interchangeability with OEM parts.

It functions to replenish hydraulic fluid, maintain system charge pressure, and supply pilot oil for pump control, critical for stable operation of 90R130 pumps in hydrostatic drives. The compact, drop-in design enables straightforward installation and maintenance, reducing downtime for equipment repairs.

Suitable for a wide range of heavy-duty applications, including excavators, loaders, bulldozers, and marine hydraulic systems. It handles harsh working conditions with stable charge pressure (typically 24bar) and fits standard mounting pads of 90R130 pump housings.

This aftermarket charge pump offers reliable performance at a cost-effective price, with a 12-month warranty guaranteed. Large stock availability ensures prompt delivery, making it an ideal replacement for worn or damaged original charge pumps in 90R130 hydraulic systems.
