The Allweiler pumps are being used to move oily water in a 430 MW gas/steam combined-cycle power station constructed by Alstom for the state-owned ESB power company.
The ten Allweiler SETP-series progressing cavity pumps are installed vertically at various locations throughout the plant, moving rainwater mixed with leaked oil residues from underground shafts to oil/water separators. The pumps suck up to 48 m3/h from a maximum immersion depth of 1.6 m and with a differential pressure of 1.2 bar.
