Danfoss 741xx and 743xx Medium-Power Piston Motors are medium-duty piston variable pumps that convert hydraulic energy supplied by the pump to mechanical energy. Danfoss axial piston motors offer durable power in a lightweight, easily serviceable package by combining the design advantages of piston pumps. These motors are specially designed to meet the needs of applications that call for constant rotation at a distance from the power source.

These motors are available in two different sizes, 741xx and 743xx, with a minimum pressure of 350 bar [5076 lbf/in2] and a maximum pressure of 370 bar [5400 lbf/in2]. These motors are suitable for various mobile and industrial applications, providing high-performance options. Furthermore, these motors are lightweight, durable housing, which is not only durable, but also allows for easy access when the time comes to service the motor. With motor's balanced architecture and optimized design, operators get the precision control they want.

Danfoss 741xx and 743xx motors are developed with numerous shaft and mounting options, such as three fixed displacement models and two variable displacement models that provide flexibility in possible applications. Their increased steering responsiveness while reducing costs with the Danfoss Series 25 steering control unit. Additionally, these motors are available in various configurations, including displacement, output shaft, bearing assembly, port configuration, mounting flange, and more.
