Chemical Process: Seal-less two and three screw pumps with magnetic couplings are increasingly used in the
chemical process industry. A typical service is MDA/MDI transferring where any hazardous emissions must be avoided. VOC awareness is playing an important role in selecting equipment making a seal-less Leistritz pump the imminent choice to replace piston pumps that can’t meet VOC emission standards due to packing glands. Screw pumps are also the natural choice for pumping different grades of polymers and monomers at high pressure and temperature.
