GEA separators are available with different types of drives: gear drive, belt drive, direct drive and integrated direct drive. The later is the next genuine stage in evolution in the separator construction process and works without motor shaft, gear, belts, coupling and motor bearing. The smaller number of installed components not only reduce the energy losses – they also reduce the maintenance costs, thus enhancing the availability of the machine. The space requirement of the integrated direct drive is approximately one third lower than is the case with equivalent gear or flat belt machines.

GEA separators with integrated direct drive can also be used in a very flexible manner. The bowl speed is infinitely variable within a specific range without change in transmission ratio. In addition, the maintenance process itself has been very much simplified. For instance, it is possible for the spindle to be taken out of the bearing housing only by loosening the bolts. The innovative design of the integrated direct drive also enables the motor to be replaced complete with the drive within only a few hours when maintenance work has to be carried out – this is time which is very valuable and which can be used productively elsewhere.

GEA clarifiers for industrial fluids have been designed for the purification of fuel, lube, diesel and hydraulic oil and the treatment of waste oil and MARPOL liquids. The clarifier of enclosed design is equipped with an oil level sight glass and driven by a 3-phase AC motor. Power is transferred to the bowl spindle via a flat belt. The hood of the clarifier is hinged and all bearings are splash-lubricated from a central oil bath.
