Yuken Reciprocal Pumps

These pumps have pistons installed at right angles against the pump rotating shaft in a plane including the shaft. The pistons reciprocate with alternately moving cranks or eccentric cams. Pumps suffer from discharge pulsation because they have a fewer pistons than the axial and radial types; however, they can operate at a high pressure of up to 100 MPa (14 504 psi). These pumps are used for high-pressure applications such as construction vehicles, cargo-loading machines, and press machines. In addition, they can handle water or water-containing fluids as the working fluid because of the construction to be wider area applicable for lubrication.
