What Is a Rotary Gear Pump?
A rotary gear pump is a positive displacement pump that uses rotating gears to transfer liquids from the suction side to the discharge side. As the gears rotate, liquid is carried through the spaces between the gear teeth and the pump casing before being discharged into the process line.
Rotary gear pumps are particularly suitable for transferring viscous and semi-viscous liquids where consistent and controlled flow is required. Depending on the pump design and application, they can be used for oils, fuels, lubricants, bitumen, resins, printing inks and other industrial process fluids.
Selecting the right rotary gear pump depends on several factors, including liquid viscosity, required flow rate, operating pressure, temperature, material compatibility and sealing requirements. Proper pump selection helps ensure reliable performance and efficient liquid transfer for the intended application.

Frequently Asked Questions
A rotary gear pump is a type of positive displacement pump that uses gears to move fluids. It’s made up of two or more gears that are interconnected within a casing.
Gear pumps use the actions of rotating cogs or gears to transfer fluids. The rotating element develops a liquid seal with the pump casing and creates suction at the pump inlet. Fluid, drawn into the pump, is enclosed within the cavities of its rotating gears and transferred to the discharge.
An internal rotary gear pump is typically specified for viscous fluids such as oils, bitumen, fats, syrups, chocolate and resins as the more viscous the product is, the more efficient the displacement aspect of the working principle becomes.
Rotary gear pumps are known for their reliability, simplicity, and efficiency. They can generate high velocity and pressure in a short period of time, and are suitable for high-pressure applications. They are also durable, non-corrosive, and can function in extreme weather conditions.
The very first attribute of rotary gear pumps is they can easily generate high velocity and pressure within a short period. The rotary gear pumps are highly efficient in handling both thin and high-density liquids.
