Axial Piston Variable Double Pump A20VO

Technical data sheet

Series 1 Sizes Nominal pressure/ Peak pressure60 250/315 bar95...520 350/400 barfor open circuits

FeaturesVariable pump with two axial piston rotary groups in swash-plate 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

– 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.
