Heavy-crude-oil-pipeline-applicable three-screw and twin-screw pumps are shown, described, and diagrammed in this free four-page brochure.
Twin-screw designs are cite for use predominantly at pipeline boosting stations and terminals while three-screw configurations boost pressure from laterals to the main pipeline. Both are self priming, positive displacement pumps with such shared features as deep nitrided rotors for minimized wear and abrasion.
Ruggedly constructed with few moving parts, the models are emphasized to deliver uninterrupted flow and efficiently handle low and high-viscosity crude oils. It’s noted: “as the viscosities increase, the efficiency of a screw pump will outperform any rotodynamic pump.” Both designs are hydraulically balanced and offer low pulsation characteristics.
Replaceable liner L4 (flow to 440,000 bpd; up to 1,600-psi differential pressure) or cartridge L3 (flow to 40,000 bpd; up to 2,300-psi differential pressure) come with optional coating methods for added wear prevention.
