Voltage & Power Note
This pump is rated 400 V Δ, 50 Hz, 3 phase, 59 A, which suits standard Indian 415 V, 50 Hz industrial supply directly. A 30 kW motor needs a soft starter or suitable reduced-voltage starter, correctly sized cable, and protection against overload, phase failure and earth fault. Connect the pump's thermal sensor and seal sensor to the control panel so the pump trips on overheating or seal leakage.
Safety Note
- Pump water only, including water with sand and small solids up to 10 mm; not for oil, fuel, solvents or flammable liquids
- This refurbished unit is not offered as explosion-proof and must not be used in hazardous areas
- Do not install deeper than 25 m below the liquid surface
- The pump weighs 452 kg: lift only by the lifting eyes, using rated lifting gear, and never by the power cable
- Always connect the earth conductor before use
Maintenance Tips
- Check the seal chamber oil at regular intervals; water in the oil indicates seal wear
- Test the thermal sensor and seal sensor circuits during routine checks
- Inspect the impeller and wear parts if head or flow drops
- Keep the suction strainer clear of mud and debris
- Check motor insulation resistance before installation
- Inspect the power cable for cuts and damage before each use
