Components overview   The parts of an SF pump presented in the components overview are to illustrate the variety of this type of pump.   For the sake of clarity, not all optional components are shown. Here we show the essential parts.   Gebr. Steimel is your partner for individual solutions. Talk to us without obligation if you are interested in a consultation on the standard components or even in a customized version besides the range shown here.   The marking of the ATEX-compliant assemblies made here is not sufficient for an aggregate compilation. ATEX units require advice. Example...

Flow rates SF Size Pump rate Rating Pump rate cm³/U NkW = Nominal power consumption at the pump shaft relative to a viscosity of 50-150 mm²/s (cSt). With a viscosity > 150 mm²/s (cSt), the nominal power consumption increases. The flow rate (l / min) refers to 1,450 1/min. It is reduced according to the rated speed of the engine. Deviation of flow ±5%. A viscosity of less than 50 mm²/s reduces the capacity. 1 Required drive power (20% surcharge is included).
