Radial piston pump type R and RG
Radial piston pumps are a type of hydraulic pump. They consist of valve-controlled pump cylinders that are arranged radially. The radial piston pump type R, RG and RZ has a closed pump housing. Therefore, besides use as a motor pump outside an oil tank, installation in the container of a hydraulic power pack is also possible. The radial piston pump is available with several pressure outlets which enable the same or several different flows. Type RZ is a classic dual-stage pump consisting of a radial piston pump and a gear pump. The radial piston pump type RG has plain bearings which have a longer storage life. This type is therefore used in extreme
operating conditions. Extremely high volumetric flows can be achieved by arranging up to 6 radials in parallel.
When the radial piston pump is used in the hydraulic power pack, it is suitable for use as a highly compact control system. Connection blocks and valve banks can be mounted on the cover plate of the hydraulic power packs.
Dual stage pumps type RZ
Dual stage pumps consist of a high pressure
section, i.e. a radial piston pump acc. to D 6010, and a directly mounted, play compensated gear pump forming the low pressure section. The housing of the high pressure pump provides a flange where the low pressure pump can be directly mounted. The drive shaft is designed as a thru-shaft to drive the second pump.
