RA ... m / RA B

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

RA pump

The RA multi-line pump is a unique radial piston pump with stackable pump elements. This modular pump design enables use of up to five pump elements, each with one, two or four outlets. Thus, a subsequent outlet reduction or expansion can be accomplished easily. Displacement of all outlets from a pump element is adjustable by a common setting device and features a setting range of 33-100%. The RA B pump series have a pre-assembled oil reservoir.
