Putzmeister A2FO23 Hydraulic Pump is a fixed displacement axial piston pump that serves in the boom hydraulic system of compatible Putzmeister concrete pumps. According to Putzmeister, the part is identified with number 495750 and belongs to the category of left-hand rotating hydraulic pumps. Featuring a nominal displacement of 23 cm³ per revolution, the hydraulic pump delivers a stable flow of hydraulic fluid for boom and auxiliaries requiring reliable and steady flow volume.
The A2FO23 features an axial tapered piston rotary assembly with a bent-axis configuration. It contrasts with the swash plate layout, used in many other families of hydraulic pumps. In the course of operation, the rotating drive shaft causes movement of pistons along the angled cylinder block and consequently pumping of oil inside the hydraulic pump and its delivery through the pressure outlet. The pump being a fixed-displacement pump means that volume of oil supplied remains the same while the total flow depends on the speed of rotation.
Putzmeister A2FO23 hydraulic pump is designed for open circuit operation. It gets hydraulic fluid from the oil reservoir, supplies it to the machine valves and actuators, and finally brings back oil to the reservoir. The lack of a variable displacement control makes the A2FO23 have a relatively simple working principle. Nevertheless, proper system pressure, speed, and oil delivery are key.
The Putzmeister part number 495750 should be consulted to identify this application. The whole nameplate has to be checked since rotation direction, shaft, flange and hydraulic connection patterns will determine if the replacement will match and work properly. Right-hand A2FO23 or pump with other connections cannot be fitted instead of the required left-hand A2FO23 unless it is checked if it matches.
