The plain bearings provide both axial and radial support tothe gears. The movement of the gears is sampled without contactby means of a sensor located in the cover. A special gearinggeometry ensures low pressure drop and minor sound emissionof the Volume applicationsConsumption measurementControlling of metering processesMonitoring of lubrication systemsMaterialsHousing: AluminiumGears: SteelBearing: Multi component plain bearing (P 10)General characteristicsGeometric tooth volumeVgZ=2 cm3 Max.
