Building on the standard PMSM motor, this series upgrades to AISI304 stainless steel impellers and diffusers for better performance in corrosive, high-strength, and high-temperature conditions. It’s designed for environments with high water impurity or uncertain water quality. The system includes AISI304 oil chambers and outlets, with a power range from 300W to 1500W. It features LEO’s MPPT DSDP visual controller for clear status displays, user controls, and fault detection. The controller also has automatic start-stop and soft start functions to protect and extend the pump’s lifespan, making it ideal for pure solar operation.
