Putzmeister A10VO28 Hydraulic Pump

Putzmeister A10VO28 Hydraulic Pump is employed in the accumulative hydraulic circuit of compatible Putzmeister concrete pumps. While A10VO28 represents the pump's series specification, Putzmeister application is frequently supplied in A10VO28(13)DR configuration, which provides a displacement of about 13 cm³ per revolution.

It is a compact pump that delivers the hydraulic flow for charging the accumulators and performing other machine functions. As accumulators store the hydraulic energy for further employment under demand, the pump must ensure continuous oil flow and pressure without constant work in maximum displacement mode.

A10VO28 is a variable displacement axially controlled piston pump with a swashplate construction. The pump is designed for operation in the open hydraulic circuit, which draws oil from the hydraulic reservoir and delivers it to the system before returning it to the tank. The pump flow depends on the drive speed and position of the swashplate, enabling reduction of displacement when the pressure is reached by the controller.

The DR controller is a device used for regulating the pressure. While the pressure in the system is still lower than the predetermined level, the pump supplies the necessary flow rate in order to pressurize the hydraulic circuit. With the pressure achieved, the controller starts reducing the displacement of the pump.

References 220024002 and 067370003 of Putzmeister both relate to the A10VO28(13)DR assembly. In addition, the second number can also lack the leading zero and be shown as 67370003. Both references need to be cross-checked with the full nameplate because shaft type, flange, rotation direction, hydraulic connections and the DR controller settings have to match the initial specifications.

Rexton Hydraulic provides Putzmeister A10VO28 hydraulic pumps, spares for the same and hydraulic pump repair services throughout India. The repair service includes checking of the rotating group, component replacement, controller repair, assembly and testing. Customers should provide photograph of the nameplate, Putzmeister part number, model of the machine and location where installed.
