Machines are mainly being designed to serve a certain or specific purpose. In making it, cutting edge technology and scientific knowledge is essential. Right from the ancient ages, science and technology has served the human civilisation like the most trusted friends. Initially, when he used to roam around places and lead a nomadic lifestyle and live in caves, scientific knowledge provided him the much needed confidence that he has the power to make the place a better habitable one against all odds. Previously, he used to get scared of lightning or heavy rain, but later on, he started to figure out the exact reasons behind these natural events. Also, he started to think in a rationale way which some historians regard as the day when science was born. In different ages, depending upon different situations, he has developed various tools, machines or devices to cater the specific need. Some of the times, the result has been disastrous or they have been used in wrong way but nevertheless, the practise continues even today.


As all of us are aware that utility devices are such types of machines, tools or devices ...
... which can get used in various industries for different purpose and it can be used in different circumstances with slight modifications. Pumps are such type of machine which is mainly used for the movement of fluids or liquids of diverse kind from one place to the other or between containers. But the requirement of industrial sector may be different than the chemical or the agriculture field may need a specific type of device. For these reasons, thorough research and development is going on at different places around the world to make the device customized to suit the specific need.


Mainly for air conditioning, cooling units in towers, irrigation systems, light chemical industry, machine cooling, dewatering applications, fire service or hot/ cold water circulation system, mainly centrifugal pump gets used. Now, centrifugal pump designs are being done in such a way, so that it can serve for longer hours without any damage ensuring safety for all working in the plant. Mainly made of stainless steel or cast iron, this heavy duty machine is also available with self-priming version. If this device is put in parallel, it can generate more pressure or if put in series can generate more flow of liquid.For different purpose, it can be classified into number of categories:-


a. Motor

b. Impeller

c. End suction

d. Circulation

e. Vertical

f. Horizontal

g. Regenerative etc.


Mainly, impeller pumps arethose machines which use rubber made rotors or impellers with vanes or flexible blades. Generally, the vanes or blades rub with each other and bend while rotating. They are used for specific purposes like fire service or machine cooling. Cutting edge technology is used while designing this device as it is expected to perform for a longer period of time without damage ensuring quality of rendered service.


Motor pumps typically have electric or diesel/ petrol based motor and a major variation of centrifugal type of devices.Mainly it finds its usage in different industrial fluid circulation systems.
