Can we simply believe that the machines or high performing devices or advanced gadgets which we use almost on daily basis and been using them since our childhood, were not present during the earlier days of human civilisation? Also, today, we, the human beings feel utterly confident about anything around us as we have the blessing of advanced science and cutting edge technology. But few thousands of years ago, we, the humans, used to get frightened once the evening comes in or it becomes evidently dark. We used to feel afraid at each of the sounds coming from the bushes or woods and at the cracking sound of the lightning. We used to feel scared at the sight of a rampaging animal coming out of jungle to pounce upon the cattle. Also, in earlier days, since human used to wander in groups, ferocious battles used to take place between different groups and as a result of that, huge number of deaths and devastation used to occur. In other ways, as a result of increase in population, he has the responsibility in hand to grow more crops from the fertile land which again needs meticulous planning and certain scientific techniques. Later on, when their mind tuned to rationale thinking process and their knowledge base improved, they started to invent or discover newer machines or tools or devices to tackle each of the tricky issues.He invented fire to prevent the animals from attacking them at night and to process raw meat of different animals. He devised a way to sharpen the different edges of weapons made of stones to strike the smaller animals and place a trap at the designated paths for bigger animals. Also, different weapons came into picture to save themselves from extinction at the hands of either other groups or animals. Moreover, in the agricultural field, revolution took place when human attached sharp tool made of iron to the plough to penetrate soil at depth in order to make the field more fertile. As a result of that, we can see, the ancient human groups used to search for places situated at the banks of rivers as the places are very much fertile in nature.

Utility devises are of different nature. Some of them can be used for any sector, be it smaller or bigger. Pumps are one of such types of machines which find its usage in domestic or municipal applications or mining or automobile sector to tackle different types of liquids.

For the purpose of chemical dosing of different chemicals (like chlorine, ORP and pH) for various industries, the technically superior metering pumps are being used across the globe because of attractive features like variable strokes. Also, inert chemicals are being used to manufacture them.

Also for the cause of repetitive and accurate chemical dosing, the high performing diaphragm metering pumps can be commercially viable solution since it can operate for longer time ensuring lesser downtime.Flow rate-an important parameter for any of such machines, can be altered by varying pulses or stroke length which makes it ideal choice for transferring acids and chemicals effectively.
