The centrifugal pump has long been the pumping technology of choice in many fluid-transfer applications, ranging from oil and gas and chemical production to liquid terminals supplied by pipelines, barges, rail cars, and trucks. Their operation is well-suited for high-volume transfer applications because fluid enters the pump impeller along or near the rotating axis and is accelerated by the impeller, flowing radially outward into the volute discharge port. Centrifugal pumps also work well with water-like fluids that must be moved through piping networks with variable flow rates. Still, in fluid-handling operations that are critical to many industries, a different technology — positive displacement twin and triple screw pumps — can be a more versatile, reliable, and efficient alternative to centrifugal pumps. This article demonstrates how effective screw pumps can be as a replacement for centrifugal pumps. A family of highly efficient and versatile twin and triple screw pumps is des...

Pumping technology keeps on developing, with increasingly more particular pump systems accessible for specific applications. Centrifugal pumps have been the norm for some industries for a long time. In any case, an ever-increasing number of operators are searching for   screw pumps   to deal with specific materials. Throughout the long term, the pumping technology of choice in numerous fluid-transfer applications — from oil and gas and chemical production to fluid terminals that are provided by pipelines, barges, rail, and trucks — has been the centrifugal pump. Their technique for operation — fluid enters the pump impeller along or close to the rotating axis and is accelerated by the impeller, streaming radially outward into the volute release port — makes them all around intended for high-volume move applications. Centrifugal pumps additionally perform generally well with water-like liquids that should be moved through funneling networks with variable flow rates. Major Diffe...
