Hydraulic Pumps

The most common type is the gear pump. This is used in many applications, such as agricultural machinery, construction machinery, hydraulic units, timber pallets and many more, and is available in various flange and shaft designs. Gear pumps with aluminium casings are usually suitable for pressures up to a maximum of 280 bar. 
Axial piston pumps are available for open and closed hydraulic circuits. Axial piston pumps are available in so-called swash plate and swash axis designs. Axial piston pumps can be operated at high speeds and are also suitable for pressures up to 450 bar. Other types of hydraulic pumps include vane pumps and radial piston pumps. These are often found in industrial applications such as plastic injection machines or test benches. Information on the calculation and design of hydraulic pumps can also be found in our hydraulic blog.
