General Notes
16
– Variable pump with two axial piston rotary groups in swashplate design for use in open circuit hydrostatic drives – For use in mobile and stationary applications – The pump consists of proven components from the A11VO (RE 92500), A10VO/53 (RE 92703) or A4VSO (RE 92050) variable pumps – The pump operates under self-priming condition, with tank pressurisation or with charge pump (sizes 190...260) – A wide variety of controls are available – Setting of the constant power control is possible via external adjustments, even when the unit is operating (only with power contol). – The pump is available with a through drive to mount a gear pump or a second axial piston pump – Output flow is proportional to drive speed and pump displacement and is steplessly variable between maximum and zero displacement

General Notes – The pump A20VO is designed to be used in open circuits. – Project planning, assembly and commissioning of the pump require the invovement of trained personnel. – The working and functional ports are only designed to accommadate hydraulic piping. – There is a danger of burns from the pump and especially the solenoids during and shortly after operation. Suitable safety precautions, e.g. protective clothing plan. – The characteristic curve may shift depending on the operating status (operating pressure, fluid temperature) of the pump. – Tightening torques: - The tightening torques specified in this data sheet are maximum values and may not be exceeded (maximum value for screw thread). Manufacturer specifications for the max. permissible tightening torques of the used fittings must be observed! - For DIN 13 fastening screws we recommend checking the tightening torque individually according to VDI 2230 Edition 2003. – The data and information contained herein must be adhered to.
