Overview of Twin Screw Pump
A twin screw pump is a positive displacement rotary pump designed for stable, low-pulsation fluid transportation in harsh industrial and oilfield conditions. Different from centrifugal pumps that rely on speed to generate pressure, twin screw pumps deliver fixed volume flow according to screw rotation speed, making them extremely reliable for variable viscosity, gas-containing, and contaminated media.
Vigorous Pump specializes in the R&D and manufacturing of heavy-duty twin screw pumps. Our screw pump series covers low to high flow rates and medium to high pressure working conditions, serving oil & gas, petrochemical, refining, marine, and industrial fluid transfer projects worldwide.
Unique Advantages of Twin Screw Pumps in Harsh Conditions
Most industrial fluid transfer failures are caused by unstable flow, cavitation, seal leakage, and poor adaptability to high-viscosity fluids. Twin screw pumps effectively solve these common pain points:
- Strong gas tolerance: Able to handle multiphase flow with oil, water, and gas mixture, avoiding pump shutdown caused by gas locking
- Stable flow regardless of viscosity: Works well with light diesel, crude oil, heavy fuel oil, bitumen, and polymer-containing liquids
- Low shear transportation: Gentle fluid delivery protects medium properties, suitable for process fluid transfer that requires stable composition
- Low NPSHR design: Optimized suction structure greatly reduces the required net positive suction head, effectively preventing cavitation in limited suction conditions
- Durable sealing system: Optional API 682 mechanical seals adapt to high-temperature, high-pressure, and corrosive working environments, extending service life
NPSH Performance & Cavitation Resistance
Cavitation is one of the biggest threats to oilfield pumps, which causes vibration, noise, flow attenuation, and even permanent damage to the pump body. Vigorous twin screw pumps are optimized for suction performance with low NPSHR.
For safe operation, the on-site system’s NPSHA (Available Net Positive Suction Head) must be higher than the pump’s NPSHR (Required Net Positive Suction Head). Our engineering team provides professional NPSH calculation and pump selection guidance to help customers avoid cavitation risks and ensure long-term stable operation.
