Tsurumi 50TMA2.4S Titanium Automatic Seawater Pump for Saltwater Aquaculture with Semi-Vortex Impeller

Managing automated aquaculture and saltwater pond circulation requires metallurgy that prioritizes liquid purity and structural longevity. Built for automatic marine drainage, this pump is configured for handling aggressive marine water and corrosive industrial liquids without manual oversight. Its non-toxic lubrication and corrosion-resistant frame ensure a clean and safe environment for sensitive fish farming and aquatic research programs.

Flow performance peaks at up to 300 L/Min with a maximum head of 12 m, driven by a 0.4 kW / 240v single-phase motor. Integrated level control automates start-stop cycles based on site requirements, protecting the motor against potential dry-run damage. This unit is continuous-duty rated through a 50 mm discharge bore for stable dewatering.

The semi-vortex impeller enables 10 mm solids passage, ensuring that suspended particles move through the pump casing with minimal contact. This arrangement is ideal for automated transfer of liquids carrying organic debris, as the impeller configuration minimizes direct contact to prevent obstruction. The hydraulic behavior maintains operational efficiency while resisting the abrasive effects typical of saltwater.

Construction features 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 sensitive automated aquaculture applications.

FEATURES

• Integrated level control provides automatic operation, reducing energy consumption in marine sumps.
• Titanium and resin build ensures outstanding corrosion resistance for saltwater pond circulation tasks.
• Semi-vortex impeller facilitates the displacement of 10 mm solids while reducing wear on internal components.
• Liquid paraffin lubrication ensures the pump is non-toxic and safe for automated fish farming.
• Dual-face mechanical seals with silicon carbide lower faces provide superior protection against abrasive sand.
• Miniature thermal protector embedded in the motor winding directly cuts the circuit during excessive heat.
• Watertight cable entry with an anti-wicking block protects the motor from moisture incursion via conductors.
