WELL CAST FOUNDRY GOPI PUMPS & SPARES GOPI GRILLS
As the correct selection of raw-material satisfying the chemical composition and mechanical / physical properties in accordance with related IS standard is the root of quality product. The material at various stages are selected according to pump duty, environment condition e.g. power supply condition, nature of water to be lifted, thermal behaviors of bearings & other critical components / assembly etc.

Technical Specification & Materials of Construction :

  • The specification and construction of material for submersible pumpsets shall be as per the details given on the products page. Scientific interferences / clearances have been provided in various assemblies of stator, rotor and pump considering reliability and longer life.

  • The impellers are dynamically balanced as per precision grade of ISO standards. Each pump assembly is hydrostatically pressure tested for 1.5 times maximum discharge pressure of the pumpset for soundness of material used and for reliability as per the ISO standards. Also stator and rotor are vacuum impregnation at 700 mm of Hg. for 5 minutes. to add more reliability to the pumpset. The rotor is epoxy coated and dynamically balanced to precision grade as per ISO standards. The rotor shaft is provided with S.S. Sleeves of grade 12 Cr 13 confirming to ISO standards.

  • The flat pvc cable confirm to ISO standards. The pumpset conform to ISO standards and the motor conform to the required standards. The motor will be supplied with cable leads of minimum 5 metres length externally. General description of material is given below.
