Solar Hand Pumps- environment friendly technology

A solar hand pump is a water pumping device that utilizes solar energy to draw and pump water from a bore well during the day and offers an option to store water in an overhead tank, for use when solar energy is not available. It is an eco-friendly and sustainable use of technology without any impairment to the environment. Since it only requires solar power for operation, it proves to be more cost-effective than the pumps that use electricity.

The solar-powered submersible pump can be installed on a bore well and operates on the electricity generated by the solar array. Batteries are not required for power storage. The submersible pump directly stores water in an overhead tank, for use in the absence of power from the solar array. The set up is convenient and simple, which entails no operational costs, while the cost of maintenance is also relatively low.

The pump head is made up of stainless steel and the body is lightweight. The size of the operating head can be chosen from 15m to 90m as per requirement. The pump discharges water ranging from 500 to 4500 liters per hour. The pump can be installed in bore/tube wells of 100mm and above diameter and requires a brushless DC or a specially designed AC motor for operation. The voltage requirement of the motor ranges from 30 to300 volts, depending on the quantity of water drawn. The optimum rate speed of the pump is 500rpm and can reach a maximum of 3600rpm. Monocrystalline or multi-crystalline photovoltaic cells are fitted into an aluminum frame to create the solar array. A galvanized piping structure is used for mounting the solar array, which makes it corrosion resistant. The solar panel can also be tilted in any suitable direction for the optimum utilization of the panel. The power output of the panel ranges from 500-2000 watts at 15 to 100 volts, and the operating temperature ranges from 40 to 80 degree Celsius. A deep well hand pump can also be installed on the same bore, using riser pipes, as a backup, for assurance against lack of solar power.

The solar hand pumps manufactured at Aakash International use the best quality raw materials acquired from trusted vendors of the industry. Also, strict quality control measures and adherence to industry standards are followed to ensure that only the superlative quality reaches the customers. The products are designed keeping in mind the varied needs of customers and a wide range of globally sought-after products developed using high-end technology and, can be procured at modest and affordable prices.

Exceptional features of the Extra Deep Well Hand Pump

Machinery is designed to make people’s lives easier. So it is almost arbitrary that it is designed keeping in mind the ever-dynamic conditions and needs of people. The India Mark II extra deep well hand pump, designed with this thought, is a conventional lever action hand pump designed for lifting water from extra deep sources, i.e. where the static water level is deeper than usual, and eliminates the use of conventional wells. This requires these pumps to be sturdy and strongly built.  The maximum recommended lift for these pumps is 80m. Since the installation and maintenance of these pumps require special skills and tool sets, which exceed the ability of the village caretakers, they are not considered to be VLOM (village level operation and management) pumps. However, specifically trained area mechanics are available to install and maintain these pumps

The India Mark II extra deep well hand pump is a modified version of the India Mark II, better suited for deeper static water levels. The down-hole components consist of a brass lined cast iron cylinder and a brass plunger, which has a triple cup seal of Nitrile rubber. The rising main is of Ø 32 mm (1 ¼”) GI pipe and the pumprods are of galvanized steel with M12 connectors.  It has a stroke length of 10mm that delivers a water discharge of 12 liters per minute, at 40 strokes, which is capable of serving hygienic drinking water to small village communities of up to 200 people, with 10-15 households. 

The handle of the extra deep well hand pump has a bigger cross section and tee-bar attachments with extra weight, which helps in reducing the manual effort while pumping. Since the water is lifted from a deeper than usual level, it is imperative that extra effort would be required to draw it out. But the counter weights attached to the handle assist in the movement of the handle while in use, and thus reduce the manual effort to a minimal. The number of counter weights varies in accord with the exact depth at which the cylinder has been installed. No weight is required for 50-60m depth, one weight for 60-70m depth, two weights for 70-80m depth and three weights for 80-90m depth. The pump head, handle, water tank, pump stand and pump rods are made of galvanized steel, rising main of galvanized GI pipe, pump cylinder cast of iron or brass, and plunger and foot valve of brass. This pump does not have a corrosion resistant quality and should advisably not be used in areas with aggressive water (pH value < 6.5).
