C.R.I. Silver line Series deep well / bore hole submersible pumps are multistage centrifugal type supplied with radial or mixed flow impellers for higher head and flow requirement. All the metal and non-metal components that come into contact with the liquid are made of stainless steel and food grade engineering thermoplastic. The optimized hydraulic design offers maximum efficiency at deeper installation. Floating impeller design can handle little higher sand than the normal pump and reduce the down thrust load that is transferred to motor. All mounting dimensions are in accordance with NEMA standards.
