Blackmer® S Series Screw Pumps are self-priming, double-ended positive displacement pumps that offer outstanding performance in the most demanding applications regardless of temperature, viscosity or pressure. The twin and triple screw designs provide complete axial balancing of the rotating screws and their timing technologies eliminate metal-to-metal contact within the pump.
Blackmer S Series 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. Other features of Blackmer S Series pumps include compact design, ability to run dry for short periods, high suction lift and constant flow rates despite varying conditions. They are low noise and nearly pulsation-free with little fluid agitation, making them ideal for use with corrosive and non-corrosive, low or high viscosity, and clean or abrasive liquids.
