Generally, machines, devices, gadgets and tools get used for some specific purposes only in our day to day lives. If we feel hot, we turn on the fan and more modern technique includes turning on the air conditioner or cooler. Or else, if we feel it is too much cold within the room, we can even turn on the room heater. If we want to talk to our close ones, we can call them on land-phone or mobile or can see them in Skype or video chat. So, indeed we can see that science and technology has gifted us host of machines or utility devices which are really useful depending upon specific situations. It would not have been possible had human not learned to start thinking in rationale way to find out the reason behind every occurrences happening around him. Once, he became aware of the reasons, he started to feel confident and within his mind, fear of the unknown got wiped out at once. So, we can truly say that science and technology had been most true friend of humankind through the ages, starting from Stone Age till the modern age of computers and smart phones.
Utility devices are such type of tools or machines which get used across sectors be it agricultural sector or mining, be it automobile or aviation. Pumps are one of these types of utility devices as across sectors, fluids or liquids of diverse nature are needed to be moved from one place or container to another. Some of the times, the liquids are dangerous, chemically reactive, and hazardous in nature and hence, if proper care is not being taken then wreak havoc. So, while designing this heavy duty machine, proper safety must be given higher importance along with the intended features.
For any mining industry, completely different set of newly developed machines are used as mining is being done under tough environmental conditions like higher temperature and pressure. Now, the process of extracting metal from the ore is indeed a complicated process having a number of intermediate stages. Depending upon the time, the dewatering pumps are expected to move fluids which are either pure liquids or mixture gases and liquids or some of the time liquids with solid particles or else, chemically hazardous acids or minerals. The mixture is so much toxic in nature that it can attack the machine interior if the issue is not properly addressed. Also, the expectations from these heavy duty machines are different as large amount of investment is being done to form the plant. So, main expectation of the sector is keeping the cost of operation and maintenance minimum, ensuring maximum yield the plant has to target profitability and efficiency.
Now, for chemical processing, movement of resins and adhesives, viscous liquids and paints, mine dewatering applications, aod pumps or air operated diaphragm pumps are used globally because of their highly attractive features like dry running and self-priming and most importantly, anti-freeze or anti stall mechanism. Now this machine does not need any lubrication and leak free due to absence of pistons or plungers.
For the same type of operations aodd pumps get used which generally comes with various accessories to suit the specific need.
