Historical perspective
efficiency. Reduction of speed would make the driver run on part-load. So, even if pumpefficiency remains good, the wireto-liquid efficiency may not. And for all the concern of planners for energy-conservation and their consequent interest in pump efficiency, there are also other concerns no less important,
such as concern for the environment, concern for safety and concern for reliability. Perhaps considering these concerns as being weightier, the eighth edition of API-610 in the footnote of Table 4.2 declares, “Efficiency is not a rating value”. Is this the right approach to strike the balance between different concerns?

The Indian pump industry is nearly a century old. Major usage of pumps has always been for agricultural pumping or for other water-handling applications. Before the spread of electrification, pumps were either hand pumps or diesel engine driven pumps. But things have changed and India has now become a formidable manufacturing base. Today more than 90% of India has electric power supply, covering even tribal hamlets in hilly terrains. Agricultural practices have also undergone a sea-change. Industrialisation has spread far and wide and there has been growing urbanisation. This has caused the installed capacities for generating power to continually lag behind the demand for power. The Indian pump industry has kept pace with the times and has continually catered to demands of pumps from all sectors, for power generation - thermal, nuclear, pumped storage, etc., for other infrastructure sectors like steel, mining, cement, oil, etc., and range of industrial sectors like fertilisers, insecticides, pesticides, pharmaceutical, paper, vegetable oils, dairies, breweries, etc. There have been two pump manufacturing companies with major foreign capital holding before globalisation of the Indian economy, which was set into motion a decade back. There have been technical collaborations from all over the world, notably with technologies from acknowledged world leaders in pumps. Also, all after-sales service support to customers was always and essentially provided by the Indian companies themselves. Indian technologists have thus shown adeptness to tackle application engineering and trouble shooting aspects as well indigenously. Apart from demonstrating capability to handle assignments like pumping in deep sea oil-exploration, the Indian pump industry is well versed in using advanced techniques for designing both pumps and sumps.

Indian pump industry has been exporting pumps to more than 60 countries around the world, admittedly though, its share in the global pump market has been insignificant. One reason for this has been that the indigenous market has been large enough for the industry to thrive and survive. AIs6 many technical collaborations limited access to global markets for Indian manufacturers. To some extent these limitations were compensated by unbranded buybacks. It is to its credit that the Indian pump industry has shared the confidence of the collaborators, as shown by the
fact that the buy-back contracts have been uninterrupted for more than two decades.

Even prior to globalisation, India’s pump industry has had an impressive track record of exports, contracts won for Indian projects from global tenders. The Indian pump industry has also lent support to global construction contractors and OEM suppliers by manufacturing and supplying globally competent and competitive pumps for the global contracts.

The Indian Pump Manufacturers Association (IPMA) was formed in 1951 and now has a membership of more than 150. These companies accounts for nearly 90% of total production of pumps in India. The IPMA has an excellent track record of participating with many Government bodies On a range Of national issues. Power generation in India always lags behind the demand f or power. The IPMA has shared the national concern for energy conservation, especially because pumping accounts for nearly 60% of the connected load. With nearly 10 million agricultural pumpsets of average drive rating of 4 kW, agricultural pumping alone accounts for 40% of the connected load for the 100,000 MW installed power generation. The energy load would be less because an agricultural pump runs for some 1200 hours per year. This has given rise to the national concern for the growing gap between demand and generation of power. Concern ‘for energy conservation need not be seen as an issue of concern only for India. Power generation worldwide depends heavily on oil and petro-deposits of oil are not going to last forever.
