Thick liquids and sludges need to move in a smooth even flow. A screw pump uses turning screws to carry them along without pulsing.
As the screw turns, it carries the liquid steadily forward in the spaces along its threads, giving a very smooth flow.
This guide explains what a screw pump does, where it fits, and how to keep it reliable.
What a Screw Pump Does
A screw pump has one or more screws turning inside a close casing, and the liquid is carried along in the spaces between the threads.
As the screw turns, the liquid moves steadily forward, which gives a very smooth flow with little pulsing.
So it moves thick syrups and sludges gently and evenly along their line.
Where It Fits in the Plant
Thick syrups, sludges, and other heavy liquids arise through the process, and these suit a screw pump.
Anywhere a very smooth even flow of a thick liquid is wanted, a screw pump handles it well.
By moving these liquids smoothly, it keeps thick liquid duties flowing steadily.
Signs a Screw Pump Needs Attention
A screw pump in trouble shows up in flow and running.
- Flow falling as the screw wears
- Rising strain on a thick liquid
- The flow turning less smooth
- Leaks at the seal
- Vibration or noise while running
What Makes a Good Screw Pump?
A screw pump is judged by very smooth flow and a sound screw.
Very Smooth Even Flow
The turning screw must carry the liquid in a very smooth even flow. Smooth flow is the reason for the screw pump.
A Sound, Close Fitting Screw
The screw must fit its casing closely to carry the liquid well. A sound close fitting screw keeps the flow steady.
Keeping a Screw Pump Running
Routine attention keeps a screw pump moving your thick liquids.
- Watch the flow for signs of a worn screw
- Watch the drive for strain on a thick liquid
- Watch that the flow stays smooth
- Keep the seal and drive maintained
Common Questions About Screw Pumps
One or more screws turn inside a close casing, and the liquid is carried along in the spaces between the threads, giving a very smooth even flow.
Thick syrups, sludges, and other heavy liquids that need a very smooth even flow with little pulsing.
The turning screw carries the liquid steadily forward rather than pushing it in pulses, so the flow is very smooth, which suits thick and delicate liquids.
Watching flow for a worn screw, watching the drive for strain, watching that the flow stays smooth, and maintaining the seal keep it moving thick liquids.
Smooth Flow for Thick Liquids
A screw pump carries thick syrups and sludges in a very smooth even flow with a turning screw. Smooth flow and a sound close fitting screw are what make it right for heavy liquids.
If a thick liquid needs a very smooth flow, a screw pump suits it. Explore our pumps and plant equipment for the right choice.
