Submersible 4w

Detailed Product Description

Mahavir 4w Submersible Pumpsets are wet-type motors of a single-phase and three-phase type, with squirrel caged rotor, suitable for operation when completely immersed in water or water-based mixture. They are of the rewindable water bath type. The Pump radial hydrodynamic layout reduces the axial dimensions of the hydraulic elements, as well as avoiding elaborating an elevated number of stages to be used in order to obtain high pressures with modest flows.

Mahavir 4w Submersible Pumpset are available in Cast Iron Version , Stainless Steel version for normal and heavy-duty motor. Stainless steel 316 version for acidic water.

Pumpsets are suitable for water well of minimum size 4" (100mm) or larger water wells. Continuous rating in 5º C to 25º C water as per IEC 60034-1.
