Danfoss hydraulic pumps work on the rotary displacement principle, where a set of gears, vanes or pistons rotate in a sealed chamber to generate hydraulic pressure. The exact mechanism depends on the type of pump, Danfoss offers several options including gear pumps, piston pumps and vane pumps.

With a gear pump, two interlocking gears rotate in opposite directions within the housing. Fluid is drawn through the inlet and flows into the space between the gear teeth. As the gear rotates, fluid flows around the outer perimeter of the housing and exits through the outlet port. Flow is determined by the size and speed of the gears.

In a piston pump, a set of reciprocating pistons move back and forth in a cylinder block. The pump has inlet and outlet ports through which they draw fluid in and expel it through the outlet port as the piston moves. Flow is determined by the size and number of pistons, as well as their stroke length and speed.

A vane pump has a rotor with sliding vanes that rotate within a cam ring. As the rotor turns, the vanes are pushed outward by centrifugal force and form chambers that draw fluid through the inlets. As the rotor continues to turn, the vanes retract and compress the fluid, forcing it out through the outlet port. The flow rate is determined by the size and number of blades and the speed of the rotor.

Danfoss hydraulic pumps are designed to provide reliable and efficient operation in a wide range of industrial applications from agriculture and construction to marine and offshore.

The specific design and function of Danfoss hydraulic pumps may vary depending on the intended use and application. For example, some pumps may have adjustable displacement, allowing flow to be varied according to demand. Others may have integrated pressure relief valves to prevent damage to the system in the event of overpressure.

In addition to pumps, Danfoss also supplies a range of other hydraulic components and systems, including valves, motors and steering systems. These components work together to form a complete hydraulic system that can power and control a wide variety of machinery and equipment.

Overall, Danfoss hydraulic pumps are designed to provide efficient, reliable and long-lasting operation, ensuring that hydraulic systems perform their intended tasks with precision and ease.
