Blackmer's S Series of twin and triple screw pumps are self-priming, double-ended positive displacement pumps whose design provides complete axial balancing of the rotating screws and whose timing technologies eliminate metal-to-metal contact with the pump. They are ATEX-certified for use in explosive or dangerous environments. The pumps are available in four distinct lines, each having multiple model configurations and sizes: twin screw (WTG), twin screw with non-timing gear (NTG), multi-phase twin screw, and triple screw.
