Industrial pump solutions vary due to several factors and functions. As you can see on the website https://www.globalpumps.com.au/, pumps are required in different industries—mining, chemical, food and beverage, paint, printing, and packaging.
If you’re looking for a pump to use for your own project, finding the right one is a matter of knowing the types of pumps and the purpose or what you need them for.
What are the different models of pumps?
Widely used, this type of pump uses an impeller, a rotating blade that generates suction power or centrifugal force, effectively moving fluid through pipes.
It is driven by an engine or electric motor and is best used for liquids with low viscosity and solid concentration. If you want to move fluids with large amounts of particles, you must use a centrifugal slurry pump.
Positive displacement pump
This pumps creates an expanding cavity and contracting cavity on the suction side and the discharge outlet of the pump, respectively. The contrasting action creates pressure that pulls and pushes liquid simultaneously. This creates enough force to move liquids.
Positive displacement pumps are available in many types, including diaphragm pump, gear pump, piston pump, and vane pump.
These types of pumps are best for viscous materials.
Which type of pump should you choose?
Based on the information above, it is easy to see which pump to use with fluids with low viscosity or for viscous material.
You can also use the downloadable guide on https://www.globalpumps.com.au/ that provide details on pump specs and formulas.
The thing is that different liquids have different viscosity, so it’s not always a straightforward solution. What you use to pump water, which has a cause viscosity of 1 cP, will not be the same pump you use for Coca-Cola syrup, which has a viscosity of 20 cPs.
Here’s a quick guide of the right pumps for the 3 common mediums.
- Centrifugal style pump
- Pneumatic pump
Water’s low viscosity makes it easy to move around. The submersible pump in a centrifugal pump will suffice, while a pneumatic pump is suited for dewatering.
- Gear or lobe pump
- Tube or diaphragm pump
Because of oil’s higher viscosity, it needs a pump that can withstand increased friction. A gear or lobe pump will suit your needs provided that it doesn’t run dry. Otherwise, a tube or diaphragm pump is best.
Abrasives and slurries
- Peristaltic hose pump
- Heavy-duty slurry pump such as the SlurryPro
This type of mediums comes with solid deposits, such as metal, rocks, or other minerals. The pump you use must have the power to transport them and the ability to withstand the medium’s abrasive nature.
- Chemical transfer pumps
- Corrosive liquid pumps
Caustic solutions, hydrochloric acid, silver nitrate, and CIP fluids are just some of the most corrosive and toxic materials that need to be transferred via chemically resistant pumps. Manual handling is not just an option. Choose a pump that is resistant to chemical corrosion.
