Non-clogging screw vortex impeller "Hydrostal submersible pump"
A groundbreaking system that keeps the inside of the manhole clean by starting the pump at the ON level and operating at maximum discharge capacity!
This product is a screw vortex pump equipped with a hydrostatic impeller. The pump starts at the ON level, and at this level, it operates at maximum discharge capacity. When the inflow is low and the liquid level drops to the pre-rotation generation level, the flow through the liquid's rotation guide becomes stronger, causing a small pre-rotation to occur at this time. This system is applied to manholes, reducing the amount of residual wastewater, preventing odors caused by scum generation and sediment accumulation, and maintaining a clean state inside the manhole, making it a groundbreaking system. 【Features】 ■ High pump efficiency ■ Safe power curve ■ Non-clogging ■ Non-destructive ■ Easy flow control ■ Minimal head loss even at high concentrations *For more details, please refer to the PDF document or feel free to contact us.
