Introduction to Types of Pumps
There are various types of pumps available in the market today. This quick read summarizes the main types of pumps and their functionalities.
The type of pump that will be the ideal fit will depend on your requirement. The main function of a pump is to move fluid and the factors that affect the type of pump will be the type of fluid, the distance you want to move the fluid, and the volume of fluid you want to move.
To help you narrow down your choice there are two main types of pumps: Dynamic Pumps and Positive Displacement Pumps. Most of the pump design can be classified under these two and the work in extremely opposite ways.
Dynamic pumps can be broken down into various types of pumps and the most common types are discussed below.
1. Centrifugal Pumps
This type of pump is the most common pump used in almost all types of applications. The principle behind a centrifugal pump is quite simple and is well tested. Therefore, a centrifugal pump is efficient, strong, and cheap.
The pump works by using the pressure difference between the inlet and outlet. The change of pressure will displace the liquid within the system.
2. Vertical Centrifugal Pumps
Also known as cantilever pumps, this type of pump uses a shaft and maintains a design that allows the volume of fluid to reduce within the pit.
The most common application of a vertical centrifugal pump is a parts washer.
3. Horizontal Centrifugal Pump
This type of pump consists of either two or more impellers. Horizontal centrifugal pumps are used for pumping services and each stage in the pump is a divided pump.
All the divide pumps are placed in the same casing and fitted on to the same shaft. On a single horizontal shaft around 8 stages can be mounted. Every divide pump adds a similar pump force to the head.
4. Submersible Pumps
These types of pumps are used in sewage, stormwater, and septic applications. As the name suggests this type of pump is submersed in the liquid.
5. Fire Hydrant Systems
Hydrant pumps are also known as firewater pumps, hydrant boosters, or simple as fire pumps. These are very high force pumps that help firefighters put out fires.
Positive Displacement Pumps
1. Diaphragm Pumps
AOD pumps or Air operated diaphragm pumps are used in continuous applications like mining, or industrial plants. ADO pumps are fitted in places where power is not an option or incombustible and unstable areas.
AOD pumps have two diaphragms which are driven by condensed air.
2. Peristaltic Pumps
The Peristaltic pumps are also known as tube pumps. They are mainly used in the food, water treatment, and chemical industries. You can use these pumps to measure exact amounts and blend ingredients together.
This just a quick guide on the most common type of pumps. The ideal type of pump will depend on your requirement and application.
