It processes clean water containing sand up to 150 g\/m³ and supports continuous duty for high-demand irrigation networks.\u003c\/p\u003e\u003cp\u003eA 2.2 kW three-phase motor at 415V drives the 20-stage assembly, achieving a peak head of 107 meters and a maximum flow of 160 L\/Min. The motor flange coupling conforms to NEMA standards, ensuring seamless integration with standardised 4-inch submersible motors.\u003c\/p\u003e\u003cp\u003eDurable LEXAN floating impellers move axially against polycarbonate diffusers, helping to prevent stage seizure when sand particles enter the casing. This design supports consistent operation across the performance range.\u003c\/p\u003e\u003cp\u003eAISI 304 stainless steel forms the external jacket, with a delivery casing incorporating a built-in non-return valve to protect the motor from reverse rotation and hydraulic shock during shutdown.
