Tsurumi 40TMA2.25S Titanium Automatic Seawater Pump for Saltwater Aquaculture with Semi-Vortex Impeller

Automating seawater transfer and marine drainage requires a reliable pumping solution that combines corrosion resistance with integrated control. This unattended pumping system is intended for site drainage where oxidation from saltwater immersion is a primary concern. Its chemically inert titanium construction ensures durability while maintaining reliable automated operation in coastal environments.

The 0.25 kW / 240v single-phase motor delivers up to 240 L/Min with a maximum head of 9 m. Integrated level control provides automatic start-stop operation based on liquid level, ensuring energy-efficient dewatering and protecting the motor against dry-run damage during intensive coastal drainage cycles. This configuration is ideal for hands-free operation.

The semi-vortex impeller crafted from glass-fiber reinforced technopolymer enables the passage of solids up to 10 mm. This hydraulic design moves suspended debris away from the impeller vanes, minimizing mechanical wear and reducing the risk of clogging. The arrangement is essential for handling saltwater with suspended matter in automated cycles without risking mechanical failure.

Construction utilizes high-grade titanium and engineering resin, supported by dual mechanical seals and a patented Oil Lifter for continuous lubrication. Structural components are protected by an internal miniature thermal protector and an anti-wicking cable entry that shields the motor from moisture. The use of non-toxic liquid paraffin as a lubricant makes the pump suitable for automated aquaculture applications.

FEATURES

• Integrated level control provides automatic start-stop operation for unattended site drainage tasks.
• Titanium and resin construction offer outstanding corrosion resistance for saltwater and marine water transfer.
• Semi-vortex impeller configuration facilitates the passage of 10 mm solids without internal clogging or wear.
• Single-phase 240v motor configuration allows for easy installation in standard residential and marine power grids.
• Patented Oil Lifter technology supplies lubricating oil to the seal faces even if the oil volume is low.
• Miniature thermal protector embedded in the motor winding directly cuts the circuit during excessive heat.
• Liquid paraffin is used as the lubricant, making the pump safe for automated aquaculture and fish farming.
• Threaded oval flange discharge allows for secure connection in narrow or restricted coastal sumps.
