this pump consists of a pump head, pump stand and a handle made of galvanized steel. The downhole 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 handlebar is designed to reduce the pumping effort of the user to a minimum since the weight of the connecting rods is counterbalanced. The cylinder has a highly polished brass liner, which ensures a long life of the nitrile 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, upvc pipe variants are available.
