Radial piston pump type R, RG

Product catalog summary

Overview of Radial Piston Pump Type R, RG
The radial piston pump types R and RG are designed for delivering lubricating hydraulic fluids and generating counter-pressure. They are versatile, suitable for both external motor pump applications and installation within hydraulic power packs. The RG type, with plain bearings, is ideal for extreme conditions. Key features include high efficiency, compact dimensions, and fine delivery flow gradation. Applications range from high-pressure systems to agricultural engineering.

Design and Assemblies
The pumps are valve-controlled with radially arranged cylinders, driven by eccentrically fitted bearings. They are dynamically balanced for smooth operation. Assemblies include types 7631, 6010, 6011, 6012, 6014, and 6016, with specific cylinder types installed in each.

Available Versions
Versions vary by basic type, delivery flow coding, seals, and supplements. The R series uses roller bearings, while the RG series uses plain bearings. Delivery flow coding specifies flow rates, displacement volumes, and operating pressures for different assemblies. Seals include NBR, FKM, and EPDM options. Supplements like explosion-proof versions and hard coat housing are available.

Parameters
General data includes installation position, line connection, and speed range. Efficiency losses may occur with certain viscosities, pressures, and speeds. The pump can be attached via a flange and driven by a flexible coupling, with any rotation direction permissible.

Dimensions
Dimensions are specified for various assemblies, detailing port sizes and installation requirements.

Installation, Operation, and Maintenance
Guidelines cover intended use, assembly information, venting, commissioning, and maintenance. Specific instructions are provided for slightly charged pumps and general operating procedures.

Specifications
Bell housings, flanges, and couplings are available for standard motor sizes 71 to 200 L. Motor power is assigned according to DIN 42677. Increased speed conditions may reduce maximum pump pressure. Flow direction is determined by suction and pressure connection, independent of rotation direction. Hydraulic fluid should comply with DIN 51 524 Parts 1 to 3 and ISO VG 10 to 68. Viscosity range varies by type, with R 0.18 to R 2.27 allowing 4 - 800 mm2/s and R 0.3 to R 91.2 allowing 4 - 1500 mm2/s. Biodegradable fluids are suitable up to +70°C. Cleanliness should follow ISO 4406 standards. Operating temperatures range from -40 to +80°C for the environment and -25 to +80°C for hydraulic fluid.

Weight
Weights vary by assembly and number of cylinders, ranging from 2.5 kg to 39.1 kg.

Pressure and Volumetric Flow
Operating pressure depends on piston diameter. Suction side pressure ranges from -0.3 bar to +1 bar.

Characteristic Lines
Noise levels are measured under specific conditions, with smaller piston diameters tending to lower noise levels.

Installation, Operation, and Maintenance
Intended for hydraulic applications only. Safety measures and warnings must be observed. The product should be assembled and operated by specialists within specified parameters. Venting is necessary during commissioning and after oil changes. For slightly charged pumps, sealing lips should face inwards for pressures above 0.4 bar.

Operating Instructions
Documentation must be accessible and up-to-date. Overloading components can cause injury. Hydraulic fluid purity is crucial, and new fluid should be filtered.

Maintenance Information
Regular inspections and cleaning are recommended. External leakages should be addressed immediately.

Other Information
Spare parts and accessories are available through HAWE Hydraulik. Power consumption calculations are provided, with efficiency factors depending on pump configuration.

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 bearings...
