When it comes to selecting the right pump for your petroleum equipment needs, understanding the differences between rotary and centrifugal pumps is crucial. Each type of pump has its own unique working principle and fluid handling capabilities, making them suitable for specific applications in the petroleum industry. In this article, we will delve into the working principle, fluid handling characteristics, and various comparisons between rotary and centrifugal pumps to help you make an informed decision for your equipment requirements.

What is the difference between a centrifugal and rotary pump? A centrifugal pump is a rotodynamic pump with radial flow, while a rotary pump is a broad category of positive

Working Principle

Rotary Positive Displacement Pumps

Rotary lobe pumps fall under the category of positive displacement pumps. These pumps operate by trapping a certain amount of fluid in a chamber and then forcing it through the pump to create flow. The rotary motion of lobes or gears within the pump chamber helps in displacing the fluid continuously, resulting in a consistent flow rate. This positive displacement action makes rotary pumps ideal for applications where precise flow control and high viscosity fluids are involved.

Centrifugal Pumps

On the other hand, centrifugal pumps are classified as dynamic pumps. Unlike positive displacement pumps, centrifugal pumps use centrifugal force to impart kinetic energy to the fluid, which is then converted into pressure to move the fluid through the system. The rotating impeller within the pump generates a high-velocity flow that is then converted into pressure as the fluid exits the pump. Centrifugal pumps are known for their high flow rates and are commonly used in applications where continuous flow is required.

Fluid Handling

Rotary Lobe Pumps

Rotary lobe pumps are well-suited for handling viscous and shear-sensitive fluids. The gentle pumping action of rotary pumps helps in maintaining the integrity of delicate fluids without causing excessive shear or agitation. This makes them ideal for transferring high-viscosity liquids such as crude oil, heavy fuel oils, and bitumen in the petroleum industry. The ability of rotary pumps to handle shear-sensitive fluids without compromising their quality makes them a popular choice for many applications.

Centrifugal Pumps

Centrifugal pumps, on the other hand, are more suitable for handling low to medium viscosity fluids with minimal solid content. These pumps excel in applications where high flow rates and moderate pressure requirements are essential. Centrifugal pumps are commonly used for transferring light oils, gasoline, and other fluids with lower viscosity levels in petroleum equipment setups. Their ability to efficiently move large volumes of fluid makes them a preferred choice for various industrial applications.

Positive Displacement vs Centrifugal Pumps

The choice between positive displacement and centrifugal pumps often comes down to the specific requirements of the application. Positive displacement pumps, such as rotary lobe pumps, offer precise flow control and are ideal for handling viscous fluids with varying viscosities. They are also capable of generating high pressures, making them suitable for pumping against high resistance.
