With thousands of combinations, gear ratios, hydraulic pump adapters, mounting options, and more — we can configure a pump drive to your design specifications. Modular approach Built for quiet operation, our pump drives are available in four series up to 708 kW (950 hp) and equipped to operate as independent mount, direct-engine mount, or clutch-driven units. Adapters are available in a variety of engine housings and flywheel sizes. Integration support You will also appreciate our integration support network. Our application engineers can help you select the options that best fit your needs....

Funk Modular Pump Drives The performance and reliability of a hydraulic pump drive is directly related to the proper selection of the pump drive series and options. Follow the steps below to determine the options required for your application. Selection of the proper pump drive series can be accomplished by using either the "torque method" or "power method" described below. 1. Determine the net peak torque (lb-ft, or Nm) transmitted to the pump drive from the prime mover. Remember to deduct any continuous parasitic losses. 2. Determine the maximum pump drive input torque (lb-ft, or Nm) required...

Important notice The presence of torsional resonant frequencies in the system can cause damage to components in the drivetrain. The assembler of the drive and driven equipment is responsible for ensuring that damaging torsional resonant frequencies are not present in the system. Torsional vibration analysis can be made by the engine manufacturer, torsional coupling supplier, and independent consultants. John Deere is prepared to supply the torsional data relating to the pump drive components and assist in evaluation of analyses in order to prevent damage to transmissions designed and manufactured...
