Hydraulic Pistton P6/P7/P8/P11/P14/P24/P30/M6/M7/M8/M11/M14/M24/M30 Parker Denison Gold Cup Motor Pump
P6D P6P P6S P6V P6W P7D P7P P7S P7V P7W P11P P11S P14P P14S P14V pump.
Parker GOLD CUP series of hydrostatic piston pumps and motors delivers exceptional, longlasting performance in severe duty applications. Featuring a robust barrel bearing design, GOLD CUP pumps and motors provide circuit reliability at speeds up to 3600 rpm at 5000 psi continuous pressure or 6000 psi intermittent pressure.
A closed circuit design makes GOLD CUP series pumps and motors ideal for bi-directional function and eliminates energy losses associated with circuit valving. The GOLD CUP's high power-to-weight ratio, compact package, and flexibility in control options and mounting locations deliver significant value-added benefits. These include lower operating costs, ease of installation with fewer components, and longevity for reduced down-time.
Details regarding the choice of hydraulic fluid
The correct choice of hydraulic fluid requires knowledge of the operating temperature in relation to the ambient temperature: in a closed circuit the circuit temperature. The hydraulic fluid should be chosen so that the operating viscosity in the operating temperature range is within the optimum range - the shaded area of the selection diagram. We recommended that the higher viscosity class be selected in each case. Example: At an ambient temperature of X °C an operating temperature of 60 °C is set. In the optimum operating viscosity range (shaded area) this corresponds to the viscosity classes VG 46 or VG 68; to be selected: VG 68. Please note: The case drain temperature, which is affected by pressure and speed, is always higher than the circuit temperature. At no point in the system may the temperature be higher than 115 °C. If the above conditions cannot be maintained due to extreme operating parameters, please consult us.
