Description: Pumps are devices that help to move fluids such as gases and liquids through mechanical action. At times, they can be used to move slurries. Pumps operate through a rotary or reciprocating mechanism that requires mechanical energy to move the fluid under consideration. Their designs are meant to perform a number of issues such as pumping water from wells, pond filtering, and water cooling in the car industry. They are also used to pump oil in the oil industry. Today, there are three main types of pumps in the industry. 1. Centrifugal water pumps: These pumps are designed to raise the pressure of a liquid in order to move it from one point to another. Over 95% of the industrial and home pumps are centrifugal models. Many people prefer them because they are cheap, easy to operate and maintain. The pumps are designed with a set of curved vanes that rotate when submerged in the liquid to be pumped. The rotating vanes build a centrifugal force that forces the water through the exit. It is important to note that centrifugal pumps only work when they are submerged. If some air gets into the pump, it becomes unable to force the water through. Therefore, you will need to clear the air before pumping can resume. 2. The peripheral pumps: These pumps are commonly known as regenerative pumps and have many similarities with centrifugal pumps. However, they differ in the way they are able to discharge heads even at low rates. To use peripheral pumps, it is prudent to establish the optimal pressure that can be developed at zero flow condition. 3. Self-priming pumps: These are centrifugal pumps designed to resolve the air problem in most centrifugal models. The pump prevents air binding by mixing the water with air to create a standard fluid that can be pushed by the pump in a normal way.
