High pressure radial piston pump
[-Increase Picture-]

Beinlich Pumpen has more than 50 years of experience and know-how in the field of gear dosing and radial piston pumps. Over the past five years it has developed from being a simple hydraulic pump manufacturer into a specialist delivering customer-specific pump solutions.

The component assemblies of the high pressure radial piston pump product line have been re-designed to ensure the shortest possible delivery time in combination with the maximum flexibility.

Both the open and encased designs have been maintained in order to secure an optimal fluid supply and to avoid ventilation problems at tank installation.

Special solutions can now be produced with minimal design modifications. With extended shafts, for example, the maximum utilisation of oil tank volume can be achieved which allows for self ventilation. Beinlich also offers specially designed drive shafts.

Due to the increasing occurrence of specialist fluids, Beinlich now offers a wide range of seal materials, e.g. NBR, EPDM, FKM and PTFE. The shaft sealing can take the form of a shaft sealing ring, a mechanical seal or a maintenance-free magnetic coupling. Special materials are also used for piston elements and housings. For non-lubricating fluids special coating materials are applied. In all applications, however, the emphasis is on component design to achieve the rapid delivery times required by customers.

Through the star-shaped arrangement of the valve-regulated piston elements, two to eight piston assemblies can be installed. At present, piston elements of various calibres are available, each delivering a theoretical output between 0.14 to 1.34 cc per revolution.

Using a combination of piston elements, outputs from 0.3 to 10.7 cc/rev per pump star can be achieved. A parallel assembly of up to 5 stars provides many possible delivery volumes up to a maximum of 53.5 cc/rev. Smaller piston calibres reach a working pressure of 700 bar. Many applications require pumps with several pressure outlets. This is achieved through the modular construction of the pump. Pumps with up to 24 pressure ports have been successfully installed. Beinlich supplies these multi-pumps either with a casing or as an immersion pump without a casing.
