It performs reliably in clean water containing sand up to 150 g\/m³ and is rated for continuous duty.\u003c\/p\u003e\u003cp\u003eDriven by a 0.75 kW three-phase motor at 415V, the 14-stage assembly delivers a peak head of 86 meters and a maximum flow of 50 L\/Min. The motor flange coupling conforms to NEMA standards, ensuring seamless integration with standardised 4-inch submersible motors.\u003c\/p\u003e\u003cp\u003eEach hydraulic stage incorporates LEXAN floating impellers that move axially within the stage casing, helping to prevent seizure when sand is present. This design reduces internal wear and supports consistent operation across the performance range.\u003c\/p\u003e\u003cp\u003eAISI 304 stainless steel forms the external jacket, with a built-in non-return valve in the delivery casing to protect the motor from reverse rotation and water column weight during shutdown.
