C.R.I.'s solar centrifugal monoblocks are surface pumps for suction applications — drawing from canals, rivers and reservoirs with up to 6 m of suction lift on SM-series models. The range spans 1 to 5 HP in both AC and DC versions, with heads up to 30 m and daily outputs reaching 437,515 litres on the largest model.

AC models use totally enclosed fan-cooled induction motors in 2-pole or 4-pole versions with C.R.I.'s 3D HT hydraulic design. Like the rest of the range they run on solar power through the Solar Pump Controller V4.0, cross-linked below; the range is MNRE empanelled.
