Detailed information on product performance and use: the A2F quantitative piston pump / motor has a fixed displacement pump or motor in the open or closed system for the hydrostatic transmission when used as a pump, the flow rate and the number of revolutions proportional to the use as motor, the number of output revolutions and proportional to flow and inversely proportional to the displacement of the output torque with high-pressure side and the low-pressure side of the differential pressure increases with increasing Features: The cylinder block and an oil pan using spherical surface with the oil, the rotation is smaller, peripheral speed, high efficiency; drive shaft to radial loads; low noise characteristics: A2F of Bent Axis quantitative pump for open loop hydrostatic driven. Suitable for walking mechanical or industrial areas. Output flow and drive speed and displacement is proportional to. Its drive shaft bearings are designed so that the field of application to achieve a desired service life. Variety of specifications to match with each actual drive. Favorable power / weight ratio; compact, economy. Best volumetric efficiency, one piston with a piston ring design.
