How to choose the right type of pump

Choosing the right type of pump is crucial for successful fluid handling operations. Pumps are used in a variety of industries including water treatment, chemical processing, and oil and gas. With so many pump types available, it can be overwhelming to choose the best one for your specific application. In this article, we will discuss factors to consider when selecting a pump and provide an overview of some common pump types.

Factors to Consider

Before choosing a pump, it is important to consider several factors including:

How to choose the right type of pump

1. Fluid Properties – It is essential to know the characteristics of the fluid you will be pumping. Factors such as viscosity, temperature, and corrosiveness can greatly impact the pump type selection.

2. Flowrate – The rate at which the fluid needs to be pumped is a critical factor in selecting the right pump. Ensure that the pump’s flowrate matches your operation’s requirements.

3. Head Pressure – The head pressure refers to the pressure required to move the fluid from the pump’s inlet to its discharge. Understanding your operation’s head pressure requirements is necessary to select an adequate pump.

4. System Design – Consider the overall system design when selecting a pump. Factors such as pipe size, distance between the pump and the discharge point, and the height difference between the two points can impact the pump selection.

Common Pump Types

There are several pump types commonly used in industrial environments. Below are some of the most frequently used pumps:

1. Centrifugal Pumps – These pumps use a rotating impeller to create a centrifugal force, which moves the fluid through the pump. They are commonly used for high flow, low viscosity fluids.

2. Positive Displacement Pumps – These pumps work by trapping a fixed amount of fluid and moving it through the pump via a mechanical action. They are commonly used for low flow, high viscosity fluids.

3. Diaphragm Pumps – These pumps work by using a flexible diaphragm to move the fluid through the pump. They are commonly used for abrasive and corrosive fluids.

4. Submersible Pumps – These pumps are designed to be fully submerged in the fluid they are pumping. They are often used for wastewater and slurry pumping.

5. Gear Pumps – These pumps use gears to move the fluid through the pump, providing a consistent flowrate. They are commonly used for high viscosity fluids.

Conclusion

Choosing the right pump is critical for efficient and effective fluid handling operations. By considering factors such as fluid properties, flowrate, head pressure, and system design, you can select a pump that best suits your specific application. Whether you require a centrifugal pump for high flow fluids or a positive displacement pump for low flow/high viscosity fluids, there is a pump type suitable for your operation.
