Antriebswellenende Drive shaft end Shaft seal Wellendichtung Getriebe Gear Gehäuse Housing Lagerbuchse bushes Plain bearing Product Features Working Notes Gear pumps KF are used for pumping a wide variety of fluids. • The fluids should ensure a certain minimum lubricating properties, should not contain solids and should be chemically compatible. Gear pumps KF are distinguished especially by their wide range of variants which are assembled as required on the modular principle and also permit subsequent upgrade. The pumps are also suitable for media with low lubricating properties. The standard...

• Sealing of the drive shaft: – Single radial lip-type seal – Double radial lip-type seal (Quench) – Mechanical seal The following should be note for direction of rotation: • when looking at the pump shaft end, the direction of pumping is from left to right if the shaft rotates clock wise. • Outboard bearing to take up input drive-side radial load • Pressure valve for pump and system Without pressure relief valve pump shaft end, the direction of pumping is from right to left if the shaft rotates c o u n t e rc l o c k w i s e. • Uniform discharge flow direction with changing direction of rotation...

KF 2.5...630 noise optimized for medias with increased air percentage The noise optimized pumps in the KF series are designed for conveying for medias with increased air content, predominantly for use as lubricating oil pumps in gears. Special measures prevent the otherwise normally increased noise present in auriferous gear oil. The noise levels do not exceed or only barely exceed the measurements with non-auriferous oils. Also, there is no noise spectrum shift to higher, unpleasant frequencies. In applications without auriferous portions in the media, it is not recommended to use this version...
