6" Stainless Steel Series |
|
|
|
 |
C.R.I. 6" Stainless steel series submersible pumps are made
of corrosion resistance stainless steel with built in
stainless steel check valve for years of trouble free
service. All vital components are made of anti-corrosive
high quality 304/316 grade stainless steel and the shaft in
SS 431/329 and well designed for the best possible hydraulic
efficiency. Pumps are multistage centrifugal type and the
optimal design of impellers and diffusers enables the best
possible hydraulic efficiency. The pump is firmly coupled to
a submersible electrical motor which operates submerged
beneath the surface of water. Built in check valve prevents
back flow and reduces the risk of water hammering. C.R.I.
submersible pumps can be offered with C.R.I.- W Series water
filled rewindable submersible motors or any other NEMA
Standard motors.
