Rotary and centrifugal pumps are some of the very basic and commonly applied pumps in various industries. Understanding the practical aspects of these pumps is crucial for anyone working with fluid handling systems. In this article, we will delve into the different types of rotary pumps, compare rotary pumps with centrifugal pumps, explore the functions and definitions of rotary pumps, and discuss their applications in specific industries such as alcohol production.
Today we want to examine the key differences between two pump types: centrifugal pumps and rotary pumps. What engineering principles make them unique? What are their strengths and weaknesses? Which applications
Different Types of Rotary Pumps
Rotary pumps are a type of positive displacement pump that work by trapping a certain volume of fluid and then displacing it through the pump to the outlet. There are several types of rotary pumps commonly used in industrial applications:
1. **Gear Pumps**: Gear pumps consist of two gears rotating in a closely meshed casing. As the gears rotate, they create a suction force that draws in the fluid and then pushes it out through the discharge port.
2. **Vane Pumps**: Vane pumps use rotating vanes to move the fluid through the pump. The vanes slide in and out of slots in the rotor, creating chambers that trap and move the fluid.
3. **Screw Pumps**: Screw pumps, also known as progressive cavity pumps, use a helical rotor inside a stator to move the fluid from the suction side to the discharge side. The screw action of the rotor creates a continuous flow of fluid.
4. **Peristaltic Pumps**: Peristaltic pumps use a flexible tube or hose that is squeezed by rollers or shoes to move the fluid through the pump. This gentle pumping action makes peristaltic pumps ideal for handling shear-sensitive fluids.
Rotary Pump vs Centrifugal Pump
While both rotary and centrifugal pumps are used to move fluids, they operate on different principles. Centrifugal pumps use centrifugal force to move the fluid, while rotary pumps use positive displacement to push the fluid through the pump.
Rotary Pump
- **Function**: Rotary pumps work by trapping a specific volume of fluid and then displacing it through the pump.
- **Definition**: A rotary pump is a type of positive displacement pump that uses rotating elements to move the fluid.
- **Types**: Gear pumps, vane pumps, screw pumps, and peristaltic pumps are common types of rotary pumps.
- **Applications**: Rotary pumps are used in various industries for precise fluid handling, such as in chemical processing, food production, and pharmaceutical manufacturing.
Centrifugal Pump
- **Function**: Centrifugal pumps use centrifugal force to move the fluid through the pump.
- **Definition**: A centrifugal pump is a dynamic pump that uses a rotating impeller to create centrifugal force and push the fluid through the pump.
- **Types**: Centrifugal pumps can be single-stage or multi-stage, depending on the number of impellers used.
- **Applications**: Centrifugal pumps are widely used in water treatment, HVAC systems, and irrigation systems for their high flow rates and efficiency.
Rotary Pump for Alcohol
In the alcohol production industry, rotary pumps play a crucial role in handling various types of alcohol, including ethanol, methanol, and isopropanol. The precise and gentle pumping action of rotary pumps makes them ideal for transferring alcohol without causing shear or degradation of the product.

Rotary and centrifugal pumps are some of the very basic and commonly applied centrifugal pumps. This blog is going to help the audience in understanding the practical aspects of rotary …
The performance of centrifugal pumps is affected when handling viscous liquids. When a fluid of high viscosity -such as heavy oil- is pumped by a centrifugal pump the performance is impaired in comparison to service with water due to increased losses. The performance is decreased comparing with water due to the increased losses.
