Ship Twin Screw Pump
Application Areas of Twin Screw Pump
- Oil field: Serves as a multiphase mixed – transportation pump, capable of transporting oil, gas, water, and tiny solid particles. It can also be used as a loading and transportation pump for various oil products.
- Petrochemical industry: Used as a loading and transportation pump for resin, pigment, paraffin, crude oil, heavy oil, and the like.
- Shipbuilding: Employed as a marine loading pump, ballast pump, and sewage treatment pump, as well as a main machine lubricating pump and fuel oil pump.
- Power plant: Functions as a heavy oil or crude oil transportation pump and a main machine lubricating pump.
- Food industry: Acts as a transportation pump for alcohol, honey, syrup, juice, fixed oil, milk, slurry oil, etc.
Special Features of Twin Screw Pump
- It can transport the liquid smoothly without any disturbing pulsation and with less vibration and low noise.
- High self – priming performance, capable of transporting oil, gas, water, and tiny solid particles.
- If the material and construction are selected correctly, it can transport all kinds of rubefacient or non – rubefacient, clean or low – viscosity, or high – viscosity media containing particulate solids.
- Various types of shaft seals are available, with characteristics of long life and less leakage, offering a wide scope of application.
Performance Scope of Twin Screw Pump
- Pressure range: 0 – 4.0MPa
- Capacity range: 0 – 2000m³/h
- Temperature range: – 20 – 300°C
- The viscosity of the medium can be up to 1×10⁶ mm²/s when the rotation speed is reduced.
