RICHMOND, Virginia -- Colfax Corp. has begun production of the world’s largest rotary positive displacement three-screw crude oil pump. The Imo 8L-912Y pump can be installed on pipelines up to 24 in. (61 cm) in diameter and can transport more than 85,000 b/d of oil at pressures up to 2,000 psi.
The hydraulic principle behind screw pump operation is to deliver high volumetric and high overall operating efficiencies, the company says. In addition, Imo 8L Series pumps offer long mean time between repairs and provide ease-of-maintenance features that maximize pipeline uptime.
Other advantages of the Imo 8L Series of pumps include:
• Constant flow, even in the presence of varying system back pressures due to changes in viscosity
• Nonpulsating flow, without the need for pulsation dampeners, eliminates stresses imposed on the pipeline system and reduces the risk of pipeline failure
• Low noise and vibration levels, minimizing foundation requirements.
“Transporting more viscous fluids with rotary positive displacement screw pumps saves energy and reduces costs compared to using centrifugal pumps for the same job,” says John A. Young, president and CEO of Colflax. “As a result, oil companies and pipeline operators are retrofitting older pipeline booster stations and, where necessary, building new pipeline networks using rotary positive displacement screw pumps to move the heavier crude oil to end markets.”
