Screw Pumps vs. Gear Pumps
Screw pumps and gear pumps are usually the pumping technology used for transferring lubricating fluids like fuels and oils among others, as they are considered more efficient than centrifugal pumps for these types of applications. Out of the two, screw pumps have several advantages over gear pumps.
- More suction capability than gear pumps, making them ideal for use in long pipelines, with more viscous oils, and when fluid contains air.
- The screw elements inside the pump are smaller in diameter than gears for the same capacity. This produces less turbulence in the fluid.
- Screw pumps work at a higher motor speed.
- Energy costs are lowered as the screw pump design ensures less power usage for the same capacity relative to a gear pump.
- The operation is much softer with less pulsations, less noise and fewer vibrations, meaning longer lifespan.
- They typically have a smaller footprint, making them better when space is an issue.
- Internal components such as the screws generally need to be replaced at the same time to ensure efficient operation, making them quite expensive to maintain.
- Suction capacity is usually less than an equivalent rated screw pump, which means less efficiency under difficult suction requirements.
- Gears need a large diameter for the requested capacity which means more pulsations in the fluid discharge.
- Larger gears limit the rotation speed. Increased RPM results in loss of suction.
- The motor uses higher power for the same screw pump. This translates to larger motor requirements and increased energy costs.
- These are noisier, more turbulent and cause more vibrations, reducing pump and pipework working life.
- Larger footprint means more room required for installation.
- The bushes and bearing internal components are in the pumped liquid, making them more subject to wear.
