It handles clean water with sand concentrations up to 150 g\/m³ and supports continuous duty for pressurised distribution networks.\u003c\/p\u003e\u003cp\u003eA 1.1 kW motor at 415V drives the 10-stage assembly, achieving a peak head of 53 meters and a maximum flow of 160 L\/Min. Mechanical standardisation is preserved via NEMA coupling, ensuring seamless integration with standardised submersible motor frames.\u003c\/p\u003e\u003cp\u003eDurable LEXAN floating impellers move axially against polycarbonate diffusers, helping to prevent stage seizure when sand particles enter the casing. Consistent operation is maintained during high-capacity transfer duty 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 prevent backflow and reduce water hammer risk.
