spirits industries and scope of submersibleOverview Of Pumps Industries And Scope Of submersible Pumps In orbicular marketIndias economy is based mainly on gardening and it is the backbvirtuoso of the country. Indias agriculture dep end ups upon the timely monsoon and the amount of rainfall in whatsoever year. To avoid the uncertainty and vagaries of the monsoon, farmers in India resort to unhomogeneous methods of irrigation. India, being a vast country with much variation in geographical conditions, ineluctably several irrigation techniques.In beas of shaldepression pissing levels (1-6 metres head axial combine or mixed period put acrossles argon employ to lift piddle. Where water levels argon at 6-40 metres head or on river sides, mostly stellate flow centers atomic number 18 utilize.For cabalistic bore wells submersible or run or compressor inwardnesss be used depending on head and displace requirements and on availability of water in the bore well (yi eld).Pumps be the vital elements in an enormous crop of fluid handling applications and digress from fine household pumps to immense units utilized in the water, chemical and slide fastener industries. Pump performance requirements and duties vary considerably in terms of fabric of construction, wide range of temperature, pressure, viscosity, density etc. Pumps argon employed in almost all the industries.Pumps diligence In IndiaThe first electric car labour in India was forged in Coimbatore in 1930 and there by and by the motor pump industry expanded rapidly there. Today 60% of Indias requirements of internal and verdant pumpsets atomic number 18 made in Coimbatore. The Southern India Engineering Manufacturers Association (SIEMA) (established in 19522)has 215 members, most of whom establish motors and pumps of diverse types. Indian pumps are made tally to the ad hocations of the Bureau of Indian Standards (BIS). Coimbatore (with 1.2 one thousand thousand population) is too famous for Textile machinery manufacture and is rated sixth in the world. It is cal occupy the Manchester of South India due to the presence of hundreds of spinning mills, textile and garment manufacturing units in and around Coimbatore.

In India, pumps are mainly used for pumping water from wells in households. With the effect of LPG (Liberalization, Privatization and Globalization) the Indian pump manufacturers have started exporting to distant countries, where pumps are used for various purposed in different industrial sectors like, oil refineries, steel mills, mines etc. This has led to the increasing trend in export of pumps.Indian Pump Industry is capturing more and more market in the world. Exported to around 70 to 80 Countries, the Indian pump industry is poised to register a quick take onth rate than the world-wide average to capture a bigger slice of the international market, states an industry.The Indian Pump industry is set to evoke at 6-7 percent over the next three years as against the world pump market, which stands at euro 10 billion and is expected to grow at 4.0 percent per annum, says by Y.I Buch, president of Indian pump Manufacturers Association, in press released published on IndiaPRwire.com.The Industry, which currently has euro 500 million global market share, is expected to grow at a rate swift than the world pump market growth, capturing a larger share of the market, states the correction released by the Confederation of Indian Industry(CII).Among machinery, pumps are produced and used in the largest numbers, southward only to electric motors.According to industry estimates, India currently produces around one million pumps of various kinds an uses worth around Rs. 900 large, medium and small units producing pumps in the country catering to a range of sectors from agriculture to industries including nuclear power generation.Indian pump manufacturers are able to meet most of the domestic market demand, states Sarita Nagpal, head of manufacturing services of CII, which works closely with the Indian Pump Mnaufacturing Association.Exported to 70 countries, inc luding developed countries, Indian pump industry exports have registered 11 percent growth in the last two years after reversing a negative 11.5 percent trend in 2002-03 to clock 45 percent growth in 2003-04.India has today become a reliable, technically competent, competitive and enterprising outsourcing option for many multinational companies in industrial pumps and systems, said Buch.The growth story has emerged through technical collaborations and joint ventures that Indian companies have had with multinational majors.Technical know how of global standard has thus been well absorbed, Buch said.In addition, various research institutes such as the Small Industries Testing and Research Centre (SiTarc) in Coimbatore, have developed energy-efficient designs for pumps to meet the norms of Indian Standards, keeping in mind manufacturing feasibility with only the rudimentary facilities of small-scale sector.The Indian Pump Industry has an outstanding record of autochthonic research an d development in all three areas of technological intensities from spile produced pumps for agriculture to gigantic pumps for interlinking rivers, and pumps for critical services such as nuclear power generation, said Nagpal.Keeping pace with changing global standards, the Bureau of Indian Standards has developed 42 sepcifications for indigenous pumps.Till go out no other country in the world has set specific norms for minimum efficiency. The norms for minimum efficiency have also been periodically upgraded, such that even the minimum norms are close to 95 percent of internationally recognized chart efficiencies, said Nagpal.Spares, Accessories, Availability And Supply To Global MarketFor each pump, a trouble shooting and repairing manual, installation and maintenance hand book and spare parts catalogue I supplied to help the node understand the procedure to follow in dismantling, reassembling and ordering spare parts. Centrifugal, monoblock, jet and submersible pumps consume m inimum spares during their lifetime.The manufacturer will specify the required spares for each pump or batch of pumps ordered and these spare parts, can be supplied with the consignment. As most of the items are in regular production, any requirement can be met at short notice and slant can be arranged.Service Assistance For Installation And MaintenanceCentrifugal Pumps are easy to install and run. For Submersible and Jet Pumps, an installation guide book is provided with each pump.Proper schooling can be provided for a few mechanics at the suppliers premises. SITARC will also have training facilities for pump assembly, testing as well as installation techniques which can also be utilized.Further a few engineers can be made available to train local people at various centres by organizing seminars and classes.Joint Venture With Local Private People.In India stinting reforms have been in progress since 1991. Joint ventures, either in India or with African countries are encouraged, d epending on the requirements. Joint Ventures either in India or with African countries are encouraged, depending on the requirements. Joint Venture in Africa is possible when the requirement of pumpsets by value is US $ 3 to 4 million per year. Interested parties can contact SIEMA.Most MNCs were initially interested in exporting to the Indian market, but soon realized the need and frugal viablility of indigenous manufacturing and working out a joint venture of foreign direct investment for manufacturing. Apart from labour being cheap, availability of technologically skilled and knowledgeable manpower with communicative competence made them to favorably consider the above. MNCs feel that manufacturing base in India can help not only to cater to this market but also to markets in Asia and Africa. culminationIt is hoped that the above information is useful. The similarity between India and Southern and East African countries in respect of soil, monsoon pattern, climate, water table, l iteracy levels, literacy levels, electric system and user method, makes Indian pumps ideal one for African countries.
