A general discussion on water pumps can be given in this chapter on Pumps. This subject is so important that it is worthy of a whole book to explain the ins and outs, but we will get to that at some other time. The subject of water pumps is so vast that it deserves only a small sample in this chapter. There are several different types of water pumps, all with different functions. There are also many different manufacturers of these pumps, all with different models and prices.
It is important to have a good understanding of the types of water pumps available for general use and as well as industrial applications, before buying a pump. Pumps are available in four main categories bom chim ebara. These are:
Vacuum pumps: this type of pump is good for producing high pressure water treatment liquids such as chlorine, ammonia, boron, and sulphur. The principle behind vacuum pumping is the pump forces a steady stream of fluid through the pipe at very high pressure. In fact the pressure can be much greater than that of the pipeline that the liquid is passing through. Vacuum pumps can be used for a variety of purposes including irrigation, dry cleaning, and industrial purposes. This type of pump also has other benefits over more common types of water treatment equipment such as gravity flow and screw pumping. Firstly, because there is no atmospheric compression between the fluid being pumped and the pump, the flow rate is higher.
Solar water pumps: this is a more energy efficient way to irrigate your lawn or plants. There is no environmental pressure on the irrigation systems as there is with water tanks or pipes. They are also safer and more effective. One of the best selling points for the solar energy pump is that you do not need sunlight to operate it. This means it can be used both in areas where it gets dark early in the morning as well as in areas where the sun is strong all day long.
Centrifugal pumps: These are typically used for irrigation systems that have a lot of surface area. The movement of the water is highly consistent, which makes it highly effective. A centrifugal pump is generally motorized and most have an impeller that rotates around a rotor. The rotors in most of these pumps spin at about thirty or sixty revolutions per minute. These are also commonly used in applications such as rocket nose cones and aerospace engineering applications.
Submersible pumps: These are the most commonly used pump in applications where the flow rate is high and consistent. They are also most efficient. The pump body itself is enclosed and it has suction holes in it in order to allow pressurization of the submersible fluids. The pump impellers are usually made from bronze, gold, or brass. The pump blades may be made from different materials as well.
