The 'India' range of positive displacement reciprocating cylinder type hand pumps are long established, robust products for general borehole and well applications. Designed to international standards, reliability has been extensively proved in a huge number of installations throughout the world, their heavy-duty construction being suitable for continuous operation over long periods. 'India' hand pumps are also simple to install and maintain at the village level using basic tools and cheap spare parts and they fulfill all aspects of UNDP/World bank hand pump specifications. Basic models are offered as follows:-
India MKII - Standard pump head with 1 1/4” GI drop pipes and 2 1/2” standard cylinder. Output is approx 15 litres/min at up to 4 2 40m depth. India MKIII - Standard pump head with alternative of 2” GI or PVC drop pipes and 2” VLOM open top cap cast iron or ‘Afridev’cylinder. Output is approximately 12 litres/min at up to 40m depth. India Extra Deepwell - Heavy-duty pump head with extended counterbalanced handle, 11/ ”gi drop pipe and 21/ ” high 4 2 pressure cylinder. Output is approximately 10litres/min at up to 90m depth. India Forcelift - Modified head with sealed water chamber to accommodate a 10m surface lift to an adjacent tank or water point with 2” GI or PVC drop pipes and 2” VLOM cast iron or ‘Afridev’ cylinder. Output is approximately 10 litres/min at up to 40m depths.
SPECIFICATIONS Pump Head Fabricated throughout from hot dipped galvanized mild steel components for corrosion protection with tri-leg pedestal design. Pregreased ball bearings are provided at the handle for long life and ease of operation. Pump stroke is 125mm. Cylinders The following options are available:
