SCREW PUMPS COST EFFECTIVE FOR HEAVY CRUDE OPERATIONS

James R. Brennan Imo Industries Inc. Monroe, N.C. In petroleum production, screw pumps fulfill the requirements for pumping crude oil with an API gravity of 20 or less (0.93 sp gr or greater). In many cases, these pumps provide more efficiency than centrifugal and reciprocating pumps. Heavy crude oils typically have viscosities at pumping temperatures in excess of 500 SSU (100 cSt).
