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
