All of the components in the Pick-A-Pack product range are designed tobe interchangeable with mating components. All components are modular in design and the "International" endhead is the key compo- nent of this interchangeable system. Any desired combination of drive motor, pump, reservoir, and control valving can be either assembled into or manifolded onto this endhead. This is available in three config- urations, with either NPTF, SAE or G3/8 porting. How to Select Pump and DC Motor Combinations: The Stone Pick-A-Pack product range is based on a system of modularconstruction which was pioneered by Stone Hydraulics when the com- pany was founded in 1968. This concept and the components utilized have been continuously refined and improved through the years. Today, Stone applies the most advanced manufacturing technologies and the highest quality materials and components available to provide this unique and extremely flexible product range. The following section contains pump/motor curves for various combina-tions of pumps and motors used on Stone hydraulic power units. It is important to select the correct motor and pump for a given applica- tion so proper pressure, flow and electrical amp draws can be accounted for appropriately in the design circuit. Proper selection also ensures the motor does not overheat and become inoperable.There are motor curves for both S2 and S3 duty cycle categories. ? S2- Absolute Continuous On-time. Indicates how long a motor can berun continuously before it must be allowed to cool back to ambient temperature.? S3- Percentage On-time. Based on a 5 minute duty cycle, it indicatesthe duty cycle (percent on vs percent off) the motor can be run contin- uously without overheating the motor.
