300-meter head stainless steel deep well submersible pump—high head, strong corrosion resistance, and designed specifically for seawater extraction!

300-meter head stainless steel deep well submersible pump Core Advantages

✅ Ultra-High Head, Stable Delivery

Designed for heads up to 300 meters, it easily handles deep groundwater or offshore platform water extraction needs.

Multi-stage impeller structure provides high efficiency and stable flow (Q-H curves can be customized according to customer requirements).

Suitable for deep wells, vertical shafts, or offshore drilling platforms with a well diameter ≥ 150mm.

✅ All-stainless steel construction for seawater corrosion resistance.

Key components such as the pump body, impeller, shaft, and guide casing are made of 316L stainless steel (904L or duplex steel optional), offering strong resistance to chloride ion corrosion.

Especially suitable for harsh operating conditions such as seawater, brackish water, and highly mineralized groundwater.

Surface polishing reduces scaling and extends service life.

✅ IP68 protection rating for safety and reliability.

Fully enclosed submersible motor with Class F insulation and IP68 protection.

Built-in thermal protector prevents dry-running and overload damage.

Cables are jacketed in a heavy-duty waterproof rubber sheath for oil and abrasion resistance.

✅ High efficiency and energy saving, low operating costs.

Optimized hydraulic model design, 10%-15% higher efficiency than industry standards.

Optional variable frequency control cabinet for constant pressure water supply, saving energy and reducing consumption.

Low vibration and noise, suitable for use near residential areas.

✅ Globally certified, worry-free export.

CE and ISO9001 quality management system certified.

Third-party test reports available.

Typical Applications:

Desalination plant raw water extraction; Deep well water extraction in coastal areas; Auxiliary water supply for oil platforms; Deep mine drainage; Constant pressure water supply for high-rise buildings; Water source pump for agricultural drip irrigation systems; Customized ship ballast water systems.
