A pump is a machine that is used to make work easy in moving of liquids like water from one place to the other with the aid of pressure. Pumps have been in use since time memorial and is still being used to date. Different advancements have been made when it comes to the use of pump technology to increase the efficiency of moving fluids like water from one place to the other. Pumps are classified into different groups all separated by how they function and where they are used.
Pumps are classified into dynamic pumps and positive displacement pumps depending on their mechanical action. Centrifugal pumps are type of dynamic pumps that operates by the difference in the fluids pressures in the outlet and inlet of the pump. The difference in the pressure is what drives the pump when pumping the fluids in a plant. The concept of a pump came when the centrifugal pump was made making it the longest existing invention. The advancements in technology has resulted into development of more sophisticated centrifugal pumps.
Submersible pumps are a type of dynamic pumps that can still operate when fully submerged in water. They are made to function while in water and a good example is the septic pumps. Another type of dynamic pump is the fire hydrant pump that is powered by diesel or electric motors. For the pump to work at its best, it has divisions that work together in ensuring that there is a proper flow of the liquids.
There are also positive displacement pumps like diaphragm pumps which are mainly driven by air. The air is manipulated in different ways to suit the condition at which the liquid is being pumped so that the pump can work effectively and give the required results. The pumps are used in ensuring that toxic liquids are moved safely to avoid any pollution. There are also gear pumps that transfer fluid through gears moving in and out of mesh creating a pumping action. They are very efficient since they can pump any type of liquids including water.
Peristaltic pumps are pumps that can be used for dosing and blending of fluids of a wide variety. They are used in chemical and water treatment plants and are also used in food processing industries. The Piston pump is a type of positive displacement pump that works when the pistons move in alternate motion with the high pressure seals. Piston pumps are very famous in various areas of production where they are used in creating and processing products into the final product.
