🔍 Key Features of the Lubi LKTW-3H 7.5 HP Borewell Pump

 

1. Precision 75-Stage Impeller System

With 75 meticulously engineered stages, this pump delivers high-pressure water lifting capacity. The multiple stages increase the pump’s ability to push water from greater depths with consistent flow and minimal vibration.

2. Water-Filled Motor for Superior Cooling

The water-filled three-phase motor enhances cooling, increases pump life, and ensures quiet operation. Unlike oil-filled motors, water-filled designs are environmentally safer and more efficient for continuous-duty cycles.

3. Premium Stainless Steel Construction

All internal and external parts are built with corrosion-resistant stainless steel, making it ideal for drinking water applications and aggressive underground environments. The casing, shaft, and impellers are all rust-proof and hygienic.

4. Integrated Non-Return Valve (NRV)

The built-in NRV prevents backflow of water, protecting the pump and reducing pipe hammering. It ensures a smooth start and stop function with minimal pressure surges.

5. Replaceable Stainless Steel Wear Rings

This pump is fitted with replaceable wear rings on the impellers that reduce wear and help restore original performance over time. This makes it highly serviceable and cost-effective in the long run.

6. Permanent Strainer Attachment

The strainer at the bottom filters out debris, sand, and other particulates that can damage internal pump components. This helps extend the pump’s life and ensures smooth, clog-free operation even in sandy borewells.

7. Compact 4-Inch Design

Fits standard 4-inch borewells (V4), making it ideal for narrow and deep wells. Its slim profile also allows easy replacement of older pumps without needing new installations.
