The TSMP Series is engineered for variable viscosity, multiphase, and gas-entrained industrial fluid transfer. Ideal for refinery, marine, chemical, food processing, pharmaceutical, and sanitary systems requiring stable flow, low NPSH performance, and adaptive hydraulic efficiency under changing process conditions.
The TSMP Series Twin Screw Pump is engineered for industrial applications where fluid behavior changes continuously during operation and process stability cannot depend on fixed operating conditions alone. Designed for multiphase transfer, fluctuating viscosity systems, entrained gas movement, and suspended-solid media handling, the TSMP Series delivers stable axial flow under conditions where conventional positive displacement and centrifugal pumps frequently lose hydraulic efficiency.
Industrial process systems in refinery, chemical, marine, food processing, pharmaceutical, and heavy manufacturing environments rarely operate under perfectly stable fluid characteristics. Temperature variation, startup viscosity spikes, vapor formation, product density shifts, and solids concentration changes create unstable operating conditions that directly affect pumping efficiency and long-term equipment reliability. The TSMP Series is specifically developed to maintain volumetric stability across these variable process environments.
Its synchronized non-contact screw geometry minimizes shear, reduces pulsation, improves suction performance, and allows controlled transfer of delicate or highly viscous fluids without excessive turbulence or mechanical degradation. The TSMP Series is widely used in applications requiring operational adaptability, process continuity, and long-duration industrial reliability.
| Hydraulic Characteristic | TSMP Series Engineering Behavior | Process-Level Advantage |
|---|---|---|
| Axial Fluid Movement | Progressive cavity transfer | Stable non-pulsating flow |
| Screw Synchronization | Non-contact timed rotation | Reduced internal wear |
| Flow Mechanism | Positive displacement transfer | Consistent volumetric efficiency |
| Pressure Development | Controlled internal compression | Reduced hydraulic shock |
| Suction Stability | Low NPSH requirement | Improved inlet reliability |
| Fluid Adaptability | Handles changing density conditions | Stable process continuity |
| Shear Profile | Low turbulence movement | Reduced product degradation |
| Gas Handling | Moderate vapor compatibility | Improved multiphase transfer |
Industrial transfer systems frequently experience changing operating conditions during startup, shutdown, thermal cycling, batch transfer, and process fluctuation. Conventional pumping technologies often lose efficiency because they are optimized for narrow operating windows rather than dynamic process behavior.
The TSMP Series is engineered specifically for adaptive process performance. Its synchronized screw geometry maintains continuous axial fluid movement even when viscosity changes dramatically between cold startup and operational temperature conditions. The low NPSH requirement improves suction stability during fluctuating inlet pressure environments while reducing cavitation risk in long pipeline systems.
In multiphase applications, entrained gases and vapor pockets can destabilize flow inside conventional pumps. The TSMP Series maintains smoother hydraulic transfer under mixed-density conditions due to its progressive cavity movement and controlled volumetric displacement behavior.

Multiphase transfer systems create significant hydraulic instability for conventional pumps because mixed-density fluids generate irregular pressure zones, vapor formation, and fluctuating suction behavior. The TSMP Series is engineered to maintain controlled axial flow under these unstable operating conditions.
Its progressive cavity movement allows smoother transfer of oil-gas mixtures, vapor-containing fluids, unstable refinery streams, and aerated process liquids without severe pulsation or volumetric collapse. The low NPSH requirement further improves suction stability during partial vapor formation and long suction-line conditions.
This operational flexibility makes the TSMP Series suitable for refinery upset systems, marine unloading operations, chemical process circulation, and variable-density industrial transfer applications.
