Transfer Gear Pumps for Fuels KF-F 2.5 ...112 Antriebswellenende Drive shaft end Shaft seal Wellendichtung Getriebe Gear unit Gehäuse Housing Lagerbuchse bushes Plain bearing 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 deter mining the tribological properties. The HFRR test acc ISO...

Transfer Gear Pumps for Fuels KF-F2.5...112 with magnetic couplingDescription The magnetic coupling serves as a shaft seal and for the transmission of the torque. The outer rotor of the magnetic coupling is assembled on the engine shaft and the inner rotor is assembled directly on the pumping shaft. The torque is transmitted through the magnetic forces between the outer and inner rotor. Between the two rotors, you have the split case which hermetically seals the pump. The magnetic coupling is used when an absolute sealing is required between the pumping room and the atmosphere. It can be used...
