KJI Hydro 4"KSE-25-4T Submersible Pump – 25 HP, 634 GPM @ 98 ft
This is an imported KJI Hydro submersible pump, model 4"KSE-25-4T, from KJI Hydro of Chicago, Illinois, USA, made in Korea. It has a 25 HP (approx. 18.6 kW) three phase motor and a 4 inch flanged discharge, and is rated to deliver 634 GPM (approx. 1.44 lakh LPH) at 98 ft (approx. 30 m) head at 60 Hz. It is supplied by Standard Machinery in Imported, Refurbished & Tested condition.
The motor is IP68 rated for continuous submersion and uses Class H insulation, which handles higher winding temperatures than standard Class F motors. The heavy cast iron volute and slow 1750 RPM speed make this pump well suited to wastewater, sewage and drainage duty, where solids and grit are present.

Voltage & Power Note
The nameplate rates this pump 3 phase, 60 Hz, 230 V / 460 V. It is a direct match for 460 V or 440 V, 60 Hz supplies (in the 460 V connection), used on ships and in several export markets.
On an Indian 415 V, 50 Hz supply, the motor is connected for the 460 V rating. Because it is a 60 Hz pump:
- Speed drops about 17%, to roughly 1450–1460 RPM
- By the pump affinity laws, the rated duty point shifts to roughly 1.2 lakh LPH at about 20 m (68 ft)
- Running current should be checked on test against the 31 A rating
For full rated performance, use a VFD set to 60 Hz output. A 25 HP motor needs a soft starter, star-delta starter or VFD, with overload, phase-failure and earth protection.
Safety Note
- The original nameplate is marked explosion-proof. As this is a refurbished unit, it is not offered as explosion-proof; the explosion-proof certification must be re-verified by an authorised body before any use in hazardous areas
- For sewage, wastewater and drainage water up to 40 °C; not for oil, fuel, solvents or flammable liquids
- Check rotation against the rotation plate before putting into service
- Lift only by the lifting handle using rated lifting gear, 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
- Inspect the impeller and volute for wear or clogging
- Check motor insulation resistance before installation
- Inspect the power cable and cable entry for damage
- Keep the wet well free of rags and heavy debris
- Check running current against the nameplate after installation
