Danfoss Series 40 M35/M44PT Axial Piston Tandem Pump is known as a medium power pump, specially designed for medium power applications. These pumps and motors can be applied together or combined with other products in a system to transfer and control hydraulic power. The product range uses the parallel axial piston/slipper design combined with a tiltable swashplate to change the displacement of the pump.

The swashplate of the pump reverses the flow of fluid by reversing the angle, which results in reversing the direction of rotation of the motor output. These pumps are available in multiple displacements from 35.0 [2.14] | 43.5 [2.65] | 35.0 x 2 [2.14 x 2] and 43.5 x 2 [2.65 x 2], with a working pressure of 380 bar to 415 bar. Danfoss Series 40 pumps feature direct displacement control and various porting options that enable a smooth and economic system concept. Moreover, it comes with a high-pressure capacity to assure higher performance.

Danfoss Series 40 pumps are constructed in compact size and lightweight, which is an ideal solution for limited space conditions. These pumps are known to provide low noise and high power density, which makes them perfect in various mobile applications such as agriculture, construction, and lawn and turf machines. Additionally, these are developed with various controls and auxiliary mounting pads to accept auxiliary hydraulic pumps.
