Material & Build – 4SRM 3/20 (2 HP)
- Pump Body: Stainless steel – corrosion-resistant and durable for long-term submersion.
- Impellers & Diffusers: Multistage centrifugal design, usually made of stainless steel or high-quality technopolymer, optimized for high head pumping.
- Motor Housing: Stainless steel, fully submersible, IP68 rated for water protection.
- Shaft & Bearings: Stainless steel shaft AISI 304, with durable bearings to handle high lift and continuous operation.
- Seals & Insulation: Mechanical seals and high-quality insulation prevent water ingress and motor damage.
Installation Considerations – 4SRM 3/20 (2 HP)
- Submersion & Positioning: Fully submerge the pump in the borehole or well and suspend vertically using a strong rope or rod.
- Electrical Supply: Use submersible-grade cable with proper grounding and a dedicated electrical line matching the pump voltage.
- Discharge Piping: Install a rigid discharge pipe with a check valve to prevent backflow; avoid sharp bends.
- Avoid Dry Running: Ensure the pump is always submerged in water for cooling and safe operation.
- Water Quality: Pump clean water with minimal sand to prevent damage.
- Maintenance Access: Maintain easy access to remove the pump for servicing.
- Head Limit: Do not operate above maximum head (≈130–140 m) to avoid motor overload and damage.
