Overview of radial piston pump type R, RG Pump elements deliver lubricating hydraulic uids while simultaneously generating a counter-pressure opposing the load resistance of a connected consumer. The radial piston pump type R and RG is versatile and can be used not only as a motor pump outside an oil tank but also for installation in the tank of a hydraulic power pack (see D 6010 H). The pumps are generally used to supply hydraulic oil to hydraulic consumers in oilhydraulic systems. Maximum installable capacity of up to 30 kW, depending on size. The radial piston pump type RG has plain...

3.4 Characteristic lines Running noise The specied noise level ranges include the results obtained from practical measurements in a test workroom with the identifiable scattering. Pumps with small ow rates (smaller piston diameters) within an assembly usually tend to be in the lower range, pumps with larger ow rates (13 to 16 mm piston diameters) are usually closer to the middle to upper range. Measuring conditions: quiet workroom with noise level at approx. 37 dB (A); measured 1 m above the ground and 1 m away from the object Measurement device: precision noise level measurement device...
