The TSO Series is engineered for continuous-duty industrial fluid transfer where process stability, hydraulic efficiency, and operational reliability are critical. Ideal for crude oil, bitumen, marine fuel, refinery and thermal fluid applications that demand low NPSH performance and stable axial displacement.
The TSO Series Twin Screw Pump is engineered for continuous-duty industrial fluid transfer where process stability, hydraulic efficiency, and operational reliability are critical. Designed for demanding environments such as oil & gas, petrochemical processing, marine fuel systems, and thermal fluid circulation, the TSO Series delivers stable axial flow even under fluctuating viscosity, pressure variation, and high-temperature conditions.
Unlike conventional centrifugal or gear-based pumping systems that suffer efficiency loss under viscous or multiphase conditions, the TSO Series maintains consistent volumetric displacement due to its synchronized twin screw design. This makes it suitable for refinery transfer systems, bitumen handling, crude oil movement, and other high-value industrial applications where downtime or flow instability can significantly impact production efficiency.
As part of a broader industrial twin screw pump portfolio, the TSO Series is positioned within our engineering-led pump solutions covering refinery-grade, marine, and heavy process industries.
The TSO Series operates using two precisely machined screws rotating in opposite directions, forming sealed cavities that move fluid axially from suction to discharge without internal contact. This design eliminates the pulsation and flow instability commonly observed in gear pumps and improves performance in systems where fluid conditions are not constant.
Whether dealing with crude oil at varying temperatures, heavy fuel oil in refinery pipelines, or bitumen in thermal transfer systems, the TSO Series ensures steady flow continuity and reduced mechanical stress on the system.
