Gear Pumps
Gear pumps are among the simplest and most widely used hydraulic pumps. They utilize rotating gears to move fluid. Sauer Danfoss gear pumps are characterized by their robust construction, high efficiency, and reliability. They are ideal for applications that require a steady flow of hydraulic fluid, such as in steering systems or work machines. The gear pump’s design allows for easy maintenance and a long service life, making it a popular choice for many hydraulic systems.
Vane Pumps
Vane pumps operate via rotating vanes within a cylindrical housing. The vanes slide in and out, creating a variable volume that helps in drawing in fluid and displacing it. Sauer Danfoss vane pumps are known for their ability to maintain a constant flow rate, even under varying pressure conditions. This feature is particularly beneficial in mobile applications like excavators and loaders, where consistent power is needed for hydraulic functions. Their compact design also makes them suitable for applications with limited space.
