Low operating costs: Pairs with energy-saving control systems, significantly cutting electricity expenses over long-term use.

Compact and lightweight structure

Integrated design: Pump shaft inserts directly into the motor’s shaft hole, creating a compact, lightweight unit suited for 20–300-meter deep wells.
Simplified installation: Operates submerged without complex pump houses, reducing footprint and construction costs.

Adaptability and reliability

Multi-scenario versatility: Handles clean water, sewage, seawater, and corrosive liquids, with a head range of 10–900 meters.
Extreme environment durability: High-temperature heat dissipation design ensures stable operation under high heat and pressure.

Operational stability

Low-vibration design: Optimized drive shaft and bearing structure reduces mechanical wear, extending service life.
Interference resistance: Cast steel housing and oil-lubricated motor design resist corrosion and sand, ensuring long-term stability.

Maintenance convenience

Modular structure: Key components like bearings and impellers allow quick replacement, minimizing downtime.
Self-lubricating system: Oil cup or clean-water pre-lubrication reduces maintenance frequency.

Eco-friendly and low noise

Green operation: Emits no pollutants, meeting environmental standards.
Quiet technology: Optimized electromagnetic design keeps operating noise below industry averages.

Customization capability

Flexible material options: Offers cast iron, stainless steel, or copper outlets to suit specific water quality needs.
High-head customization: Adjusts pump body length for well depth, with single-stage heads ranging from meters to hundreds of meters.
