Different Varieties Of Pumps
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 were discovered in the early years and are still being used in our current generation. Due to the development of technology, pumps have seen a great improvement in the way they function in making it even more easy for them to be used to move water. There are therefore different types of pipes that are used and they vary depending on the type fluid and maybe the area.
There are varieties of pumps but are placed in to two groups that is dynamic pumps and positive displacement pumps. Centrifugal pumps work based on the pressures exerted on the fluids at the outlets and inlets hence giving it the propelling action to move the liquids. The pressure in the outlet and the pressure exerted at the inlet determines how the pump will operate. Centrifugal pump has been in existence longest since it was the first concept of a pump that was invented. The advancements in technology has resulted into development of more sophisticated centrifugal pumps.
Another type of dynamic pump is the submersible pump that operates when fully submerged in water. Also known as storm pumps, submersible pumps are meant to work while in water or the liquid being pumped. Another type of dynamic pump is the fire hydrant pump that is powered by diesel or electric motors. The fire hydrant system has parts that are designed to work in solidarity to ensure the liquids are pumped in a proper manner.
There are also positive displacement pumps like diaphragm pumps which are mainly driven by air. The air used to run the pump is directed in a way that it will aid the whole system to pump the liquids in a required manner. 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. There is also piston pump that is a type of positive displacement pump that works when the high pressure seals moves alternatively with the piston in the pump. Piston pumps are used in many applications and can also be applied in the transfer of chocolate for example.
