C.R.I. 100 mm (4") Submersible pumpsets are built with thermoplastic impellers, diffusers and inbuilt check valve. All vital components of these pumpsets are made of corrosion resistant thermoplastic and the shaft is of SS 304/410. Pumpsets are multistage centrifugal type. The optimal design of impellers and diffusers enables the best possible hydraulic efficiency.
The pumpset is firmly coupled to a submersible electric motor which operates submerged beneath the surface of water. Built-in check valve prevents back flow and reduces the risk of water hammering. All mounting dimension of 100 mm (4"�) pumpsets and motors upto 2 HP are in accordance with NEMA standard. FEATURES:
- More longevity & hygiene High operating efficiency
- Floating impeller design prevents blockage
- Easy to dismantle & repair Rigid construction
- Highly durable Can handle up thrust load
- NEMA mounting standard upto 2.0 HP
- Extremely hardwearing water lubricated bearing
