Circular pumps BFP - 1

Circular pumps BFP Hydraulic and lubrication systems therefore increasingly use bypass filters and/or coolers. The advantage of these circuits is that they create stable and therefore more predictable operating conditions for both the filtration and cooling. Circulating oil in these circuits requires efficient and preferably silent circulation pumps which provide a constant flow rate at moderate pressures. Internal gear pumps, so-called gerotor pumps, have proved especially useful for these applications. They offer compact integration, are relatively insusceptible to particle contamination and have a long life. Low noise emission High vol. efficiency Good suction performance Built-in bell housing Gerotor principle Not susceptible to contamination The BFP series features a range of particularly compact circulation pumps specifically designed for this area of application.

BFP Introduction and description Why gerotor? Numerous applications in hydraulic and lubrication systems just require the circulation of the fluid. In such cases low noise emissions and low pressure ripples are more important than highly efficient transmission of energy. The gerotor is the ideal principle for such applications. The displacement mechanism consists of the inner and the outer rotor. The number of teeth of the inner rotor is always one less than the outer rotor. The rotation of the gerotor generates chambers of changing volumes between the inner and outer rotor. The variation...
