No. | Pump type | Advantages | Disadvantages | Fluid pumped | Applications |
1 | Gear pump | Simple structure Few rotating parts | Can not handle fluid included with solid | Clean, viscous fluids | Clean oil service |
2 | Lobe pump | Large flow rate Gentle pumping action | Reduced pressure with thin liquids | Shear sensitive fluids, fluid containing solid | Wastewater, slurry, biotech, sewage |
3 | Hose pump | No shaft seal, No leakage, Low maintenance | Can not handle fluid abrasive | Corrosive, viscous, shear sensitive fluids | Chemical, wineries, sewage treatment, paint |
4 | Single-screw pump | Low fluid velocity, Wide fluid viscosity application | Large size required for high pressure | Water with solid or particle | Wastewater, paper, chemical, oil, food |
5 | Twin-screw pump | Higher Temperature | More parts, higher cost | Viscous, multiphase (oil, water, gas) fluids | Oil, terminal, vessel, petrochemical |
6 | Plunger pump | High pressure, more moving parts | Low capacity, regular maintenance | Clean water, CO2 gas | Injection, cleaning |
7 | Vane pump | Good self-priming, Dry run possible | Can not handle abrasive fluid, not for higher pressure | Thin liquid, solvent, gasoline, alcohol, volatile liquid | Fuel transfer, chemical, refrigeration |
