Irrigation Pumping : Making grounds thrive with life…
The economic dynamics of India is not disseminated uniformly. Still people in the remote regions of this sub tropical country suffer from technology ignorance and dilapidated educational bloom. We have been providing irrigation pumps to major cities and remote villages since quite long with a vision to improve countries gross domestic income (GDI) that majorly credits to the agricultural productions sourcing out of these remote villages. In one of our tryst with mechanical advents and reduction of pump manufacturing costs, we were teamed and tasked under an expert from Russia, who confronted us to the terminologies and benefits of irrigations pumps.
Some excerpts from the wondrous knowledge input by our expert engineer:
He started by first unfolding the water abundance on earth majority of which is remains unused, unexploited since time immemorial! He obliged, “Though water occupies one third of this planet, Ninety-seven percent of the water on the earth is salt water. Salt water is filled with salt and other minerals, and humans cannot drink this water. Although the salt can be removed, it is a difficult and expensive process. Two percent of the water on earth is glacier ice at the North and South Poles. This ice is fresh water and could be melted; however, it is too far away from where people live to be usable.”
Next he pointed on Indian procrastinated knowledge enhancement which is still leading remotest of villages to remain scrambled away from water even if there’s surplus of underground water. He emphasized, “Majority of the stock of fresh water that is often used for drinking and irrigation purpose is generally termed as Ground Water. For many important agricultural production areas, groundwater will remain the ultimate source of freshwater when surface water sources have been depleted. Groundwater is generally less prone to pollution than surface water.”
Quiet interesting and intriguing were his views and knowledge transfer on water scarcity in India – a country considered to be the most fertile lands of the South East Asia. Little but very stimulating statements from this Russian gentleman ignited a fire inside – fire to make rural Indian aware of latest technology and extort & exploit water for prolific agricultural purpose.
Major challenge that the agriculture industry faces now is to get this stock of ground water used for irrigation and here’s when the Hero of our story “Irrigational Pumps” comes into picture. Farmers can select from a wide range of pumps for irrigation purposes. Some applications have special pump requirements, but there are many common considerations in the selection of an appropriate pump. The best pump for the job depends on the type of irrigation system that is in use. The irrigation system and how it is operated will determine the pump performance that would be employed. An irrigation pump can come along with wide mechanical diversities. Two major irrigation pumps that are used now days are the centrifugal pumps & the turbine pumps.
Mechanical Milestone Centrifugal Pump has the following advantages:
• It can be installed above the water surface.
• It can be mounted on skids for rapid removal from danger of floods.
• Not being submerged, it is less liable to corrosion, although most can operate submerged for short periods without damage.
• It can be installed as a portable unit and used at more than one pumping site.
• It is cheap to maintain.
• Where large quantities of water have to be pumped against low heads, mixed-flow volute (MFV) pumps are used.
• Another advantage is that the power requirements (for a given speed) are approximately constant through the range of head and discharge.
• Since turbine pumps are most often used for pumping from bores, there is a limit on impeller diameter and the pressure which can be developed at a given speed.
Turbine pumps can also be used for irrigation purpose because of its following benefits:
• It can be driven by an engine.
• It is less prone to damage by silt and sand in the water than the electro-submersible pump.
• It is easier to maintain than an electro-submersible unit.
• It can be used for supplies inaccessible to centrifugal pumps which would require too long a suction pipe.
• It can be used for high pressure conditions beyond the capacity of conventional centrifugal pumps.
• It can be used to pump silt or sand-laden water unsuitable for an electro-submersible pump.
Widely used for catalyzing the irrigation process in India, these two pumps are used mainly because of high productive output with minimal efforts to maintain and install. Our team has managed to install and help hundreds of villagers with large variety of irrigation pumps till date, the process which seems to be ever continuing. When all the villages of green Indian have sufficient technology encroachment, hope their will be less panics in a farmer’s family and reduced life claims owing to acute water scarcity in extreme hot summers. Proper storing and utilizing of surplus rain water in monsoon can lead to a much productive summers.
