Tsurumi 40TM2.25S Titanium Corrosion-Resistant Seawater Pump for Saltwater Aquaculture with Semi-Vortex Impeller

Coastal environments require specialized metallurgy to manage saltwater aquaculture and marine water transfer effectively. This seawater transfer pump serves as a robust technical solution for coastal sumps where high oxidation would destroy standard iron equipment. Its chemically inert titanium construction maintains liquid purity, ensuring a stable environment for sensitive fish farming and marine displays.

The 0.25 kW / 240v single-phase capacitor run motor delivers up to 240 L/Min with a maximum head of 9 m. This 2-pole dry-type induction motor is continuous-duty rated for stable performance across diverse site conditions. The single-phase configuration simplifies integration into standard residential or marine power grids without separate phase conversion.

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, reducing mechanical wear and maintaining uninterrupted flow. The arrangement is particularly effective when handling coastal sand and organic debris common in seawater applications.

The wet end combines titanium and engineering resin, complemented by a titanium shaft for exceptional seawater resistance. Internal sealing relies on a double-face mechanical seal in an oil chamber featuring a patented Oil Lifter for continuous lubrication. Protection against moisture is provided by a miniature thermal protector and an anti-wicking cable entry that shields the motor from water ingress.

FEATURES

• Titanium and resin construction ensures outstanding corrosion resistance for seawater applications.
• Semi-vortex impeller configuration facilitates the passage of 10 mm solids without risking internal clogging.
• Double-face mechanical seal with ceramic and silicon carbide faces offers superior protection against ingress.
• Patented Oil Lifter technology keeps seal faces lubricated even if the oil volume falls to low levels.
• Watertight cable entry with an anti-wicking block prevents moisture from wicking into the motor housing.
• Miniature thermal protector embedded in the motor winding directly cuts the circuit during excessive heat.
• Non-toxic liquid paraffin is used as the lubricant, making the pump safe for aquaculture and fish farming.
• Threaded oval flange discharge allows for secure connection in narrow or restricted marine sumps.
