Parker GOLD CUP® Hydrostatic Pumps and Motors for open and closed circuit ensure long-lasting performance in severe-duty applications. With a robust and flexible design, they provide operating pressures up to 6,000 psi and speeds up to 3,600 rpm

Rugged and efficient, The GOLD CUP® series boosts productivity with hydrostatic piston pumps and motors that deliver exceptional performance in the most severe applications. Featuring a robust barrel bearing design and hydraulically controlled rocker cam, GOLD CUP® pumps and motors provide proven durability and reliable pressure control.

A closed circuit design makes GOLD CUP® series pumps and motors ideal for bi-directional function and eliminates energy losses associated with circuit valving. GOLD CUP®'s high power-to-weight ratio, compact package, and flexibility in control options and mounting locations offer significant value-added benefits. These include lower operating costs, ease of installation, and improved longevity for reduced downtime.

The heavy-duty GOLD CUP® series of pumps and motors represent Parker and Denison combined expertise in hydrostatic transmission applications in marine, drilling, and shredding applications, among others. The tried and true design of the GOLD CUP® product line incorporates features such as integral servo and replenishing pump, hot oil shuttle, and a unique servo control system; all of which combine to provide a rugged self-contained package which can withstand the harshest of conditions and continue to perform with trouble free long life.
