Sauer Danfoss Hydraulic Pump is an axial piston variable displacement pump of swash plate design with changeable flow capability suitable for hydrostatic transmissions with closed-loop circuits. They are engineered to deliver high efficiency, durability, and precise hydraulic power control for mobile and industrial applications.
These pumps are made to perform optimally in challenging situations, with compact, high-strength construction, smooth operation, and compatibility with electronic control systems for enhanced machine performance.
GumaTech provides Sauer Danfoss hydraulic pumps in two series types, 51V and 90R, with four models available in stock.
51v
The Sauer-Danfoss 51V Series is a range of heavy-duty hydraulic pumps designed for reliable power transmission in demanding applications. Mostly known for their durability, efficiency, and smooth performance, they are widely used in construction, marines, agriculture, mining, and other mobile machinery requiring robust hydraulic solutions.
Series 90
It is a variable displacement pump, a compact unit with a high power density. All models utilize the parallel axial piston/slipper concept combined with a tiltable swashplate to adjust the pump’s displacement. Reversing the swashplate angle reverses the flow of oil from the pump, which in turn reverses the direction of the motor output’s rotation.
It is mainly known for its compact size, high power density, and reliability; additionally, these pumps are ideal for equipment where space and performance are critical.
Gear Pump
Danfoss aluminium gear pumps are robust and reliable, offering a pressure-balanced design, extended operating life, and modular and short versions of multi-stage units for high flexibility and compactness. Their compact design is ideal for machinery with limited space, and multiple mounting, porting, and shaft configurations ensure flexibility across applications.
