Handling thick, sticky fluids in industrial processes can be a challenge. Regular centrifugal pumps often struggle with highly viscous liquids, leading to inefficiencies or even failure.
This is where gear pumps come in. Known for their ability to move high-viscosity fluids smoothly and reliably, gear pumps are a trusted solution in many industries. In this article, we’ll explore how gear pumps work and why they’re especially suited for these demanding applications.
Introducing articles from plantengineering.com.
Gear pumps are pumps that are widely used in machinery and equipment.
They are rarely used in batch chemical plants, but there are still occasions when they are used.
We will briefly explain their features.

High viscosity liquid
Gear pumps are used for high viscosity liquids.
Diaphragm pumps and plunger pumps are also used for high viscosity liquids, but gear pumps are used for even higher viscosity liquids.
High Pressure Fluid
Transporting highly viscous liquids is almost synonymous with high pressure in the line.
This is only natural, as high viscosity means high pressure loss.
Easy to adjust flow rate
Gear pumps are easy to adjust the flow rate.
Like diaphragm pumps and plunger pumps, the flow rate can be determined almost entirely by the pump drive amount.
Note that this is “almost,” but not completely.
Beware of foreign objects
Gear pumps are prone to foreign matter generation.
This is natural because they have a mechanism that rubs metal against metal.
Unlike diaphragm pumps, one side is not made of resin, so care must be taken.
Conclusion
Gear pumps are a go-to choice for transferring high-viscosity liquids in industrial settings. With their steady flow, strong suction, and ability to handle challenging fluids, they bring both reliability and performance where it matters most. For engineers dealing with thick materials, gear pumps are often the simplest and most effective solution.
