Danfoss H1T Tandem Axial Piston Pump is designed with an advanced control and available in a variety of displacements. These pumps provide expanded functionality, greater total efficiency, and easy installation. H1 pumps are developed with quality and reliability in mind. Danfoss has been creating cutting-edge parts and systems for mobile machinery used in off-highway operations for more than 40 years.

Danfoss H1T pump is the latest generation of servo-controlled hydrostatic pumps, constructed with robust materials and advanced control management. These pumps are known for their low noise emissions and compact size, which is helpful in limited space conditions. Every H1 control and sensor option complies with PLUS+1®. You can quickly create and modify electrical machine control with PLUS+1. By integrating machine controls and diagnostics into a single operational network.

These pumps are developed in four different displacements, including 045, 053, 060, and 068, with a nominal pressure of 380 bar and a maximum pressure of 450 bar. Danfoss H1T Tandem Axial Piston Pump provides complete reliability, modularity, and controllability, which is mainly appropriate for dual-path applications. All the Danfoss hydraulic motors can be used with the Danfoss H1 range of pumps to control and transfer hydraulic power.
