Emptying tank wagons

A petrochemical company uses two ONIXline rotary lobe pumps for emptying tank wagons. The pumps with dry-run capability convey methyl tert-butyl ether (MTBE) and 2,2,4-trimethylpentane (isooctane) from the wagons to storage tanks. Due to the high chemical aggressiveness of the pumped media, pump casings were made of stainless steel. The fluids are pumped nearly without pulsation due to the steel rotors with screw profile. All O-rings are made of perfluoroelastomers (FFKM). The self-priming pumps are installed in potentially explosive atmospheres and, therefore, have an ATEX-compliant design.
