RA ... U

Mechanically or electrically operated radial piston pumps for SKF MultiFlex multi-line lubrication systems


The RA multi-line pump is a unique radial piston pump with stackable pump elements. The modular pump design allows up to five pump elements, each with one, two, or four outlets. A later outlet reduction or outlet extension is thus possible. The displacement of all outlets from a pump element is adjustable by a common setting device, setting range 33–100%. Several different mechanical or electric motor drives are available.
