Web Exclusive--Positive Displacement Pumps
November 12, 2002
Viking Pump's rotary positive displacement pumps, using gear and lobe principles, offer an alternative to centrifugal pumps in applications where system pressure or fluid viscosity fluctuates. The pumps provide a near-constant flow rate with minimal efficiency change, regardless of changes in system pressure or viscosity. Viking's high NPSHR capabilities keep fluid moving with less chance of cavitation in processes where a suction lift is required or where high vapor pressure fluid is being pumped. The pumps can handle fluids from 28 to 2,000,000 SSU viscosity.Viking Pump.
