Afridev Hand Pumps Manufacturers Exporters India

Hand pumps are readily replacing the conventional use of wells to provide a simple solution for providing hygienic supply of drinking water in rural and suburban environments. They improve the hygienic conditions under which water is drawn off, by eliminating the use of buckets and open vessels, thereby eliminating to a great extent the risk of water contamination.

The Afridev hand pump is one of the few recommended by UNICEF as pumps benefiting from its VLOM (Village Level Operation and Management of maintenance) label, in other words, robust pumps that can be fully maintained locally, either by the community members themselves or by a technician that they can call out quickly, and which are also produced locally and selected, managed and maintained by the community. It is designed for heavy duty use, with a conventional lever action that can serve communities of up to 300 people. Its maximum recommended lift is 45m and the pump is fully corrosion resistant, the bearing bushes being hot dip galvanized and made of special plastics. Alternative stainless steel lined cylinders are also available for aggressive water conditions apart from the mild steel variant. The pump comes with variable handle settings, which makes it possible to adapt to varying ground water levels at different times. The spout length and pedestal can be customized according to different needs. The assembling and dismantling of the parts is quite effortless since the foot valve fitted on to the pump can be easily retracted using a fishing tool. Rubber centralisers are provided to each connecting rod to prevent internal damage to uPVC pipes, due to corrosion. 225 mm stroke length of the handle in afridev hand pump can provide a water discharge of 1350 litres per hour with an installation depth range between 15 m to 45 m. These hand pumps have quick release eye & hook tool-less ends on connecting rods with rubber centralizers facilitate maintenance and protect the riser pipe against internal wear.  Special tools and guided installation manuals are also available with the afridev hand pumps, which makes the assembling and installation very easy. Fulcrum & Rod hanger pins are supported on special grade plastic Bush Bearings, which are easily replaceable. The uPVC riser pipe, cylinder, plunger & foot valves used in the pump are light weight and inexpensive. Additionally, rubber centralisers are provided to each uPVC pipe to prevent external damage, which further lowers the maintenance and operational costs.

Afridev hand pumps manufactured at AakashInternational have a few special features that distinguish them from other pumps available in the market. A choice of Eye & hook connecting rod or threaded connecting rod is provided. They are easy to instate and can be accomplished even by women mechanics in villages.

The afridev hand pump thus eliminates the difficulties and complexities associated with machinery and give it a user friendly quality, while solving the problem of hygienic drinking water supply in urban and suburban areas.

Deep Well Hand pumps Manufacturer Aakash International

A deep well hand pump is used when the static water level (distance between the top of the ground and top of the water level) is more than 20 meters. In most cases, the pump cylinder is installed at least 20 meters below the static water level and connects to the wellhead through a series of PVC pipes and stainless steel lift rods. Since these pumps draw water from deeper than usual levels, it is necessary that they are sturdy and strongly built. 

The Deep well hand pump can be installed in bore wells of a diameter of minimum 125mm and the internal diameter of the underground cylinder ranges from 60-65mm. the stroke length ranges from 120-130mm. these hand pumps give a water discharge of 12-15 liters per minute of 40 strokes, and an average of 900-960 liters per hour. The maximum depth of operation of these hand pumps is 30 meters. These pumps are self-priming and do not require routine maintenance. Also, they are available in different grades and dimensions, which can be customized as per the client requires. This pump has excellent “community management potential” and can be easily installed and repaired by a village caretaker or women, making it popular with small communities. The above-ground parts of the pump can be locally manufactured, but the rest of the components require a high degree of manufacturing quality, which is not available around the globe. So in some countries, these components need to be imported. However, imported components require strict quality control and check to increase the lifetime of the hand pump, and considerably reduce wear and tear of parts and disuse due to corrosion.

India Mark II Hand pump-The Backbone of community water supply

The India Mark II Hand Pump, a conventional lever action pump, is one of the largest selling hand pumps across the world. The government of India, along with the continuous and considerable efforts of non-governmental, industrial and multilateral organizations in the 1970s developed this mechanically efficient hand pump. The above ground mechanism comprises of pump head, handle, water tank and stand assemblies, and the below-ground mechanism comprises of riser pipes, connecting rods and cylinder assembly. The pump is designed for heavy-duty use and is capable of serving communities of up to 300 people.

This pump consists of a pump head, pump stand and a handle made of galvanized steel. The down hole components consist of a brass lined cast iron cylinder with a foot valve and a plunger of brass. Since this pump is not corrosion resistant and requires special skills and tools for maintenance along with installation, it is not considered to be a VLOM (village level operation and management of maintenance) pump. Thus it cannot be used in areas with aggressive water conditions. The above ground body of the pump is made of welded steel plates and is hot dip galvanized for corrosion resistance. The handle bar is designed to reduce the pumping effort of the user to a minimum, since the weight of the connecting rods is counter balanced. The cylinder has a highly polished brass liner, which ensures a long life of the nitrite rubber pump bucket.  The pump requires a circular operating space of 2m diameter and the operating depth ranged from 25-90m, and gives a water output of 900 liters per hour at 40 strokes per minute. The speed might vary, reaching a maximum of 125 strokes per minute but the ideal speed remains 40 strokes per minute. The riser pipes are 32m in diameter and GI, SS, PVC pipe variants are available.

The mark II pumps manufactured by Aakash International possess features that differentiate them from other variants available in the market. The pumping head, handle, pump stand, rising main and rods are made of galvanized steel which makes them corrosion resistant, while the pump cylinder caste and foot valve are made of brass. Also, the Indian Bureau of Standards has been adhered to while manufacturing of this product to ensure the provision of maximum quality to the customers.

Under the hand pump project of the UNDP/World Bank,   extensive trials were conducted on twelve different deep well hand pumps from all over the world, including France, Holland, Canada, Sweden, South Africa U.K., U.S.A. and India. The parameter for testing included ease of manufacture and use and installation, mechanical and volumetric efficiency, frequency of breakdowns and maintenance needed, user-friendliness and acceptability, and resistance to corrosion. Mark II emerged as the best hand pump of all through these tests, which makes it the most widely used hand pump around the world. The sturdy nature of this hand pump requires adherence to standards of quality control to eliminate broken down pumps that are not in use due to use of sub standard parts during manufacturing. At Aakash International, it is made sure that the standards provided by the Indian Bureau of Standards is adhered to, which ensures that only the best quality is provided to customers.
