It handles clean water containing sand up to 150 g\/m³ and supports continuous operational cycles for both indoor and outdoor supply needs.\u003c\/p\u003e\u003cp\u003eWith a 0.55 kW motor at 415V, the 8-stage assembly achieves a maximum head of 51 meters and a flow rate of 70 L\/Min. The mechanical interface conforms to NEMA standards, providing a secure connection point for high-performance 4-inch submersible motors.\u003c\/p\u003e\u003cp\u003eDurable LEXAN floating impellers move axially against polycarbonate diffusers, helping to prevent seizure when sand is present in the water. This design preserves the hydraulic characteristics of the pump over years of groundwater recovery service.\u003c\/p\u003e\u003cp\u003eAISI 304 stainless steel forms the external jacket, with a chrome-nickel steel delivery casing incorporating a built-in non-return valve to shield the internal stages from back-pressure and reverse rotation.
