It handles clean liquids with sand concentrations up to 150 g\/m³ and is rated for continuous operational duty for large civil infrastructure projects.\u003c\/p\u003e\u003cp\u003eDriven by a 1.1 kW three-phase motor at 415V, the 14-stage assembly delivers a peak head of 87 meters and a maximum flow of 100 L\/Min. The motor flange coupling conforms to NEMA standards, ensuring seamless integration with standardised 4-inch submersible borehole motors.\u003c\/p\u003e\u003cp\u003eAxial movement of the LEXAN floating impellers within each stage helps to accommodate sand particles and protect the internal surfaces from abrasive wear. This design supports consistent operation during high-flow cycles.\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 backflow during shutdown.
