Putzmeister A11VO60 Hydraulic Pump

Putzmeister A11VO60 Hydraulic Pump is a variable displacement axial piston pump meant for hydraulic drives that work in an open circuit. It is applied in Putzmeister concrete pumping machines where it supplies adjustable hydraulic flow in the movement of boom and other auxiliary operations in the machine. The maximum nominal displacement of the A11VO60 series is 60 cm³ per revolution; however, specific configurations of Putzmeister can have lower displacements as needed for the particular hydraulic circuit.

The pump is designed with axial piston rotary group with a swash plate mechanism. Displacement is adjusted by altering the angle of the swash plate to regulate the amount of hydraulic fluid supplied with each revolution. In an open circuit setup, the pump draws hydraulic fluid from the hydraulic reservoir, supplies it through the various machine operations, then back into the reservoir.

The official designation of Putzmeister reference number 274262001 is A11VO60(40)DRS, whereas 663075 reference is designated as A11VO60(30)DRS. Putzmeister also gives a 50 cm³ option as a different reference number. Numbers within parentheses specify the configured displacement rather than another pump family. Hence, an A11VO60(30), A11VO60(40) and A11VO60(50) are not interchangeable without considering the original machine requirements.

The DRS control system comprises pressure regulation as well as load-sensing control systems. This allows regulating the flow rate depending on the demand from the hydraulic system, thus, saving flow rate when full output is not needed. Proper controller settings are required to achieve proper boom function and effective hydraulic system work.
