產品介紹 introduction RJC series deep well pumps are new generating and energy-saving equipment for lifting water .they are with advanced structure，for they adopting the core produced with the resin sand and the impelled&diffuser adopting the new technique that topcoated with epoxy，advanced hydraulic model，excellent performance curve without hump and wide high efficiency range. The efficiency is 4-8% higher than that of Jc or JD type deep well pumps in average，for they use whirl sand device and the maze-like structure whice makes sand not able to enter the bearings，shaft checked by flame method to ensure ii’s in line .it’s a new generation pump design Copacity: ≤5000m3/h head≤350m motor power:5.5-1600KW rated voltage:380V，6KV，10KV well diameter:100-950mm max discharge diameter :650mm 應用范圍 usage RJC series deep well pumps are applied to lift normal temperature clean water without erosive for water power plant (in an overhaul and leakage)，power plant(when reduce the temperature in the recyle ，and for domestic service)，steel works(for scale pit)，fire-fighting，，urban water supply by water plant and agriculture irrgation. 型號說明 model number description 400RJC450-30*2 400-min suitable well diameter(mm) RJC-lineshaft deep well pumps 450-rated capacity 30-head per stage 2-No of stage
