Yuken Multiple Vane Pumps

These pumps are categorized into double and triple types. The double pump has two sets of cartridge kits on one shaft, and each of the kit works independently. Generally, this type contains a combination of low-pressure large- volume and high-pressure low-volume pump elements. The triple pump has three sets of cartridge kits and forms a circuit to sum up the output pressures for applications requiring a larger displacement. Figure 2.14 shows a PV2R series double pump. Figure 2.15 shows circuit examples of low-pressure/large-volume and high-pressure/small- volume combinations for press machines.
