1 End cover 2 Plain bearing bushes 3 Gear unit 4 Housing 5 Shaft seal 6 Drive shaft end I Description The Type KF-F transfer pumps were developed specifically for use with fuels, especially for marine fuels. These need to be critically considered, especially regarding the lubricity. And above all, those with low sulphur. Diesel fuels (MGO/DMA) exhibit low lubricity, which cannot be determined through the viscosity. Special methods are available for determining the tribological properties. The HFRR test acc ISO 12156 is a recognised method for measuring the lubricity of diesel fuels. The...

Technical data I Operating parameters Nominal size geom. displacement Maximum pressure Speed range Sound level Remark: * Working pressure pb = perm. sustained pressure For certain working conditions, the minimum or maximum characteristics should not be used. For example, the max. working pressure is not permissible in combination with low speed and low viscosity. In such limit ranges, please consult us. Sound level: measured in dB(A) at 1 m distance / with drive motor Installation site: Works hall, quiet sound level =
