Step-by-step material optimizationThe plant operator started using ALLWEILER pumps immediately with thefirst phase of the expansion. Based on their initial experiences, materialswere optimized one step at a time in order to achieve long service times."In the beginning, sometimes we could only keep a pump in service for afew days. But by working together with the manufacturer we quicklyoptimized the materials and now we achieve normal service times,"according to Sven Schön, a certified engineer and CEO of EOP BiodieselAG. This applied particularly to stators and rotors in the progressive cavitypumps. Temperatures up to 130 °C while drying biodiesel and pH values upto 12 in the various lye solutions make it essential to have very resistantmaterials. For this reason, gray cast pumps used in the beginning werereplaced by stainless steel versions.Centralized replacement parts suppliesThe positive experiences during the initial phase of expansion made thedecision to use the same pumps in the subsequent enlargement and newLeft: Series: CNB 25-160 pumped liquid: sour waterRight: Series: CNB 32-200 pumped liquid: RME - IIIu12Progressive cavity pump of the ANP 6.2 series with quench connectionsand receiving container (not shown).
