Alibaba option was 600k for equipment 300k shipping. Then will have to get a local installer. Works out cheaper but shipping takes 4-6wks, no idea what stories might come up the the port when clearing plus not easy to followup on warranty if equipment fails.
Those are damn expensive pumps... am assuming they were for industrial use.
A pump for regular borehole ussually ranges from 10k to 50k depending on the depth capacity and brand... I personally got the one for 24k from Davis and got my own technician to do everything else, the well is 60 feet deep though. Of course electricity connection and plumbing setup will cost much more not to mention the cost of digging the well...
A proper borehole goes beyond 100-150m. At those depths, the pump needs to be very strong - and can cost alot.
A friend dug a borehole of 150m, and out-fitting the borehole (the pump, pipes, meter, control panels, cables etc) cost at least 600K. And this was for a 3KW pump. So if you are looking for a 5.5kw pump, it will be more expensive.
