C.R.I.'s DC borewell submersible range shares the stainless-steel multistage hydraulics platform of the AC line, in 3 to 10 HP ratings for 100 mm and 150 mm wells with operating heads from 30 to 150 m. It posts the highest daily output of the C.R.I. solar range — 342,000 litres per day on the SL10D-S6S-60/04 at 30 m head.
