The Simple But Very Useful Pump

If you have ever had to go through the ordeal of pumping water out of a flooded room you know just how glad you were to have a pump around to do the job. Can you imagine having to grab a pail or bucket to scoop out the water? Tough work and you like most would rather have it done in an easier manor. So you are glad to have a pump help do the work for you. You don’t even care about the loud motor disturbing the peace of your day because you would rather the noise than the back breaking work. Still have you ever wondered how did this seemingly simple mechanism come about and how it works for new petrol powered post driver. 
You would have to go as far back as 2000 BC to the time of the Egyptians to find the first use of a machine meant to do the work of a pump. It was a simple machine with a bucket at one end of a long rod and weights at the other. In roughly the same year, 200 BC, two key inventions were created in the time of the Greeks that form the foundation of some of the very pumps you use today. One was by the lesser known inventor Ctesibius. His invention is a water organ, which forms the principle design for what we now call reciprocating pumps. The more famous inventor, Archimedes is the man responsible for the screw pump. This invention is so great that it is still being used now some 2200 years later.

Now that you have the little history lesson you will learn what is the general principle behind all pumps. Firstly, you need to know what a pump’s job is. A pump is used to move a substance, generally a liquid, from one level to a higher one. As the pump is working to move the liquid against gravity it needs to work against it to move the liquid to a higher height. It can do this by means of using an energy source to do mechanical work. The energy needed to make the pump work can come from several sources. It could be electrical, solar, wind and even manual labour. The pumps themselves normally achieve their task by using a rotary or reciprocating mechanism. They can either be in the fluid they are pumping or external to it, like the large fire fighting pumps for sale that are used by industrial buildings.
Pumps have varying uses in today’s society. They are used for irrigation for farms, or in your refrigerator, air condition systems and even your toilet. They have a number of applications and are almost as varied in size and type like the leaves on a fruit tree in bloom. So spare a thought for the engineers, inventors and scientist who have made it possible to bring this wonderful piece of machinery to you the next time you are using anything that has a pump.
