Explaining Different Types of Pumps Used in Water Treatment Plants

Wastewater treatment is necessary for your area because of climate change impacts and frequent droughts. As a result, you need to be well-equipped regardless of whether you own a commercial, residential, or industrial space.

If you own a space, you need an efficient sewage treatment plant to remove large volumes of wastewater every day. This not only helps the environment but also helps to reduce the cost of industry operations significantly.

While there are several types of sewage treatment solutions, the only component that is always present in these machines is wastewater pumps. These are used to safely transport the waste from the source to the treatment plant and then sent back.

However, there are various types of wastewater pumps that vary based on their application and usage requirements. To help you choose the right one for your sewage treatment plant, we’ve made a list of different wastewater pumps and explained them.

Let’s take a look!

Positive Displacement Pumps

Positive Displacement pumps have variations featuring unique configurations. Here are all of them:

Diaphragm Pumps

These wastewater pumps use air or hydraulic fluid to move the waste in a planned direction through the sewage treatment plant. Additionally, you can close the diaphragm to stop the flow of the wastewater to keep it under control.

It’s one of the most popular pumps used in sewage treatment plants and you need high-quality ones to ensure proper disposal. Fortunately, we at Whisspurr feature a wide range of premium diaphragm pumps available for purchase. 

Gear Pumps

These types of water treatment pumps use gears to pump fluid in and out of the sewage treatment plant. They are commonly used for hydraulic fluid power applications because of their rigid design. 

Lobe Pumps

This pump uses two or more lobes in the system that rotates around the parallel shafts in the pump’s body to move wastewater and other liquid. They’re commonly used in food and beverage processing industries. 

It should also be noted that these pumps don’t make physical contact with each other. This makes it useful to pump out certain types of materials that other pumps may find difficult to manage. 

Dynamic Displacement Pumps

The main difference between dynamic and positive displacement is their functionality. Dynamic pumps use an impeller to generate energy, whereas a piston is typically used in a positive displacement pump to create pressure. 

The biggest advantage of using dynamic displacement pumps is that they can work safely with their valves shut down. The only disadvantage is that they tend to be a little noisy while running. Fortunately, by using our AVR unit, you won’t have to deal with this problem. 

Most problems in sewage treatment plants can be fixed by yourself or with a professional. 

Now, let’s take a look at some variations of dynamic displacement pumps: 

Fire Hydrant Systems

Fire hydrants are dynamic displacement pumps that provide pressure by flowing through nozzles and pipes throughout a system. They’re used by firefighters by raising the force in the hydraulic systems. 

Centrifugal Pumps

Centrifugal pumps are used to convert mechanical energy into hydraulic energy. It functions from two key components: the volute casing and the impeller. These pumps are known to be long-lasting, efficient, and easy to make. 

Axial Pumps

Axial pumps are one of the most commonly used dynamic displacement pumps. These pumps are used to transport fluids at high speeds over a short distance. Due to this, only the pump’s flow-related activity creates energy.
