What You May Not Know About The Centrifugal Pump
Have you heard of a centrifugal pump but are not quite sure what it is or how it works? If this is your case you may want to keep reading as this article will explain to you what these types of pumps are and how they may be able to benefit you. There are many ways in which you may already be using this type of pump and you may not even realize it.
The idea for the centrifugal pump was designed from a water lifting machine that an Italian Engineer, Francesco di Giorgio Martini, invented in the year 1475. This particular machine was believed to be the prototype of machine pump that applied centrifugal force. However, the first actual centrifugal pump was not invented until 1600 by a man named Denis Papin. The pump that Papin designed has straight vanes however by the year 1851 a British man named John Appold designed a centrifugal pump that had curved vanes.
A centrifugal pump is an extremely simple design. This type of pump works by lowering the pressure of the fluid inside the impeller, and the volute channels the fluid in the direction of travel. It is made up of three parts; the volute, or casing, which is immobile, the shaft, which transfers the power from the motor or other power supply to the third part, the impeller. This is the part that actually moves the liquid through the system.
There are three types of pumps in the centrifugal pump category. You have radial flow, mixed flow and axial flow pumps. Radial flow pumps move the fluid entirely by centrifugal force, such as the way a water pump in a car works. An axial flow pump moves the fluid by imparting lift on the fluid. Lastly, a mixed flow pump uses both centrifugal force and the imparted lift on the fluid.
You need to determine what the needs and conditions are for your centrifugal pump needs. If you have a need to move a fluid over a long distance and the source will stay constant a radial flow pump will probably be the best bet. An axial flow pump will work best for pulling a liquid up and away, because even if you lose the source occasionally, this type will still maintain suction. If you may lose the source occasionally but need more pressure, you will probably want to go with a mixed flow pump.
There are many uses for a centrifugal pump, such as a sump pump, automotive water pump, and fluid circulation pump. These types of pumps are very popular because of the ease of use and lack of parts. Because these pumps have so few parts, the maintenance requirements are very small. This means that you will have more time to spend doing things other than maintaining your pump or pumps, and will also have to spend less money in maintaining and repairing them.
When it comes time to purchase a new centrifugal pump, Weir Minerals is a good place to start. With the experience available through them, you will find more than just pumps. With installation, what little maintenance your new pumps will need as well as control devices you will not have to go all over town to get the service you deserve for your needs.
