In India Hand Pumps Installed with India mark-II hand Pump assembly, start giving Sand, Mica and other foreign material after few months of running because these all are Cavity wells in which there is no provision of filter strainer.
As per the Bharti V-wire technology when well construct with the provision of numbered slot as per the sieve analysis, natural gravel paced well will br formed which runs as long as the water running in the aquifer.
To overcome with this situation of Sand, Mica etc. We have developed Hand Pump Jacket Screen which screwed on the bottom of India Mark-II Cylinder from where jacket separate the solids from the water and the fresh water without any foreign material come out with delivery line and the very purpose to serve the public with fresh drinking water will be achieved.
