Parker Gold Cup Series Hydrostatic Pumps & Motors
Parker GOLD CUP® Pumps & Motors ensure high performance in severe-duty applications. At HYDRAULIC HUB, we are one of the leading suppliers and repair service providers of Parker Gold Cup Series Hydrostatic Pumps & Motors throughout their entire sizes/frames.
Parker Gold Cup Series Hydrostatic Pumps & Motors are designed with hydrostatic transmission and used in marine, drilling, and shredding applications. The GOLD CUP® pump and motors are constructed with many features, including an integral servo and replenishing pump, a hot oil shuttle, and a unique servo control system. These features work together to create a strong, independent package that can endure the most trying circumstances and carry on operating trouble-free for a very long time.
Parker GOLD CUP® Pumps & Motors are known for providing high performance and efficiency in heavy-duty applications. With a robust design, they operate to pressures up to 6,000 psi and speeds up to 3,600 rpm. Parker has taken over the Gold Cup brand from Denison since 2004. These pumps and motors are offered in multiple models/sizes (P6 | P7 | P8 | P11 | P14 | P24 | P30) and can be used in multiple machines.
Parker and Denison's combined experience in hydrostatic transmission applications is reflected in the heavy-duty GOLD CUP® pumps and motors. These pumps and motors are designed in a closed circuit design, which makes them perfect for bi-directional function and minimizes energy losses related to circuit valving. GOLD CUP® has a high power-to-weight ratio, a compact package, and flexibility in mounting and control options, which provides precise value-added benefits.
