TWIN SCREW PUMP

Twin screw pump is type of positive displacement pump that uses two rotating screws or rotors to move fluid. These two threads interact with each other in the pump casing to form a closed space that moves fluid from the inlet to the outlet. Twin screw pumps are known for their ability to handle a wide range of fluids, including high viscosity fluids, abrasive fluids, and fluids containing solid particles, as well as their ability to provide a steady, pulsation-free flow.

Types of Double Screw Pumps

Externally Timed Twin Screw Pump:

  • Characteristics: Uses timing gears outside the pump casing to synchronize thread movement, so the threads do not touch each other.
  • Applications: Ideal for fluids that require clean, contamination-free pumping, such as in the food, beverage and pharmaceutical industries.

Internally Timed Twin Screw Pump:

  • Characteristics: Threads interact directly with each other inside the pump casing without the need for external timing gears.
  • Application: Used for fluids that are not sensitive to slight metal contamination, such as in the chemical and oil & gas industries.
