Axial piston pump, closed loop

This category brings together the Genuine Parker OEM replacement series engineered specifically for GOLD CUP® hydrostatic piston pumps, the pump family Parker markets for severe-duty, closed-loop hydrostatic transmissions. Rather than complete pumps, each series here is a factory-warranted service assembly that restores a specific part of the pump to original performance and durability — from the internal pumping components to the control interface and rotating shaft.

Across the four series, the shared thread is genuine OEM manufacture purpose-built for GOLD CUP® pumps, factory warranty coverage, and suitability for the same severe-duty sectors, including mining, cranes, construction, marine, defense, power generation, agriculture, oil & gas and material handling. What differs between them is which part of the pump each kit replaces.

Series in this category

• GOLD CUP® Basic Rotating Group — replaces the piston assembly and wear plates that form the pump’s primary pumping component.
• Gold Cup Cam and Cradle — a complete cam and cradle assembly for full replacement of that structural pumping element.
• GOLD CUP® Input Controls — manual and servo control options, including a servo system that eliminates the metal-to-metal linkage between control and pump.
• GOLD CUP® Shaft Assembly — a complete kit replacing the shaft, shaft bearing and frame-size-specific mounting parts.
