250QJH108-240-132KW Cast Stainless Steel Submersible Pump with 240m Head for Seawater Intake

The 250QJH108-240-132KW Cast Stainless Steel Submersible Pump is engineered for seawater intake, offshore platforms, desalination plants, coastal industrial water supply, and marine engineering projects.

Built with a cast stainless steel hydraulic structure, the pump combines high mechanical strength with excellent corrosion resistance for long-term operation in seawater and high-salinity environments. With a flow rate of 108 m³/h, 240 m head, and a 132 kW submersible motor, it is designed for continuous-duty, high-head water transfer applications.

For seawater intake systems, pump selection involves more than hydraulic performance. Material resistance to chloride corrosion, reliable shaft sealing, and stable long-term operation are equally important. The 250QJH series is designed to meet these requirements for demanding marine applications.

Marine environments expose equipment to chloride-rich seawater, salt spray, and high humidity. The pump features a cast stainless steel structure, making it suitable for:

• Seawater intake systems
• Marine engineering
• Offshore platforms
• Coastal industrial facilities
• Desalination projects

Available material options include:

• SS304
• SS316
• SS316L
• Duplex Stainless Steel 2205
• Super Duplex Stainless Steel 2507

allowing engineers to select the appropriate corrosion-resistant material according to water quality.

Main hydraulic specifications:

• Flow Rate: 108 m³/h
• Head: 240 m
• Motor Power: 132 kW

The multi-stage centrifugal design provides stable pressure for:

• Deep seawater intake
• Coastal pumping stations
• Long-distance pipeline transportation
• Elevated storage tanks

The pump is equipped with a 132 kW three-phase submersible motor.

Optional electrical configurations include:

• 380V
• 400V
• 460V
• 660V
• 6 kV
• 10 kV

with 50 Hz or 60 Hz frequency options to match international power systems.

The sealed motor design supports continuous submerged operation in demanding marine environments.

The modular pump structure offers:

• Multi-stage hydraulic assembly
• Compact submerged installation
• Reduced installation space
• Low vibration
• Easy maintenance access

This design is suitable for offshore platforms, seawater intake stations, and coastal infrastructure projects.

Suitable for:

• Coastal intake stations
• Marine water supply
• Seawater transfer pipelines

Ideal for:

• Raw seawater intake
• Pretreatment systems

When selecting a seawater submersible pump, engineers should evaluate:

• Water quality and chloride concentration
• Required flow rate and total dynamic head
• Pipeline length and friction loss
• Voltage and frequency requirements
• Material compatibility with the operating environment

Proper matching of hydraulic performance and corrosion-resistant materials helps support reliable long-term operation in marine applications.
