Sewage management is very crucial at different places including residential places, restaurants or hotel industry and industries where large amount of sewage is discharged every day. One of the important factors of sewage management is keeping it flowing through the drainage system or to the waste water treatment plants. Imagine if the discharged sewage is clogged through the drainage system and if it cannot pass through the system, what will happen? It is a horrible situation. But, this does not happen because this important function is handled by sewage pumps. These pumps are designed to route the fluids and solids through the system. Are you looking for sewage pumps in the market? This article will help you to know the types of sewage pumps available in the market.

Types Of Sewage Pumps
There are variety of sewage pumps developed to pump sewage containing combination of liquid and solids. There are two main technologies used in sewage pumps. These technologies are –
- Sewage pumps using centrifugal force – These centrifugal pumps create centrifugal force to push the sewage containing debris, garbage, mud etc. through the drainage system. This force creates velocity and the rotating impellers help move the sewage without clogging.
- Sewage pumps using kinetic energy – These pumps are called agitator pumps and utilize kinetic energy to pump the sewage. Generally, these pumps liquefy the sewage with kinetic energy and this makes it easy to route the sewage through the system.
The different types of sewage pumps include –
- Grinder pumps – These pumps are especially used in residential pressure sewer system. As the name suggests, it shreds the solid matters and make it easy to flow it through the system.
- Ejector pumps – These pumps apply gravitational force to route the sewage. You will find close coupled submersibles or vertical suspended type of ejector pumps in the market.
- Submersible pumps – The motor of these pumps is either oil filled or air filled and a variety of impeller designs are developed to drive solids of various particle sizes. These pumps are widely used in effluent and sewage treatment plants.
- Progressive cavity pumps – These pumps are especially designed to move dewatered sludge in sewage treatment plants.
- Hose pumps (Peristaltic pumps) – These positive displacement pumps have roller. The squeezing action helps move fluids in the system. Generally, these pumps are used in sewage treatment plants.
