Will submersible pump increase borewell yield in Coimbatore, Tamil Nadu ?

Dear Sir, 
           The bore well is situated in Coimbatore (north) region, is 500 feet deep and is run by a elgi(10hp) make water compressor and the water yield is approximately 4000 l/hr. I want to know whether there will be an increase in yield and the percentage of increase ,when I switch over to a submersible(submersible is an electric water pump that pulls water from ground and is fitted in the ground). Kindly reply as early as possible.
