Tsurumi 50TM2.4S Titanium Corrosion-Resistant Seawater Pump for Saltwater Aquaculture with Semi-Vortex Impeller

Supplying water for fish farming and large-scale coastal aquatic systems requires metallurgy that prioritizes liquid purity and structural longevity. This marine-duty pump is configured specifically for saltwater aquaculture and the transfer of corrosive liquids bearing suspended matter. Its non-toxic lubrication and corrosion-resistant body ensure a safe and stable environment for sensitive marine life and industrial processes.

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. The unit is continuous-duty rated for stable site water management through a 50 mm discharge bore. This motor utilizes a capacitor run starting method, ensuring reliable performance during high-volume drainage duties.

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 liquids carrying organic debris, as the impeller configuration minimizes direct contact to prevent obstruction. The hydraulic behavior maintains operational efficiency while resisting the erosive effects typical of saltwater runoff.

Long-term durability is achieved through a combination of 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 entirely suitable for sensitive aquaculture applications.

FEATURES

• Manufactured from pure titanium and resin to ensure outstanding corrosion resistance in marine environments.
• Semi-vortex impeller facilitates the displacement of 10 mm solids while reducing mechanical contact and wear.
• Non-toxic liquid paraffin lubrication ensures the pump is safe for aquaculture and fish farming.
• Dual-face mechanical seals with silicon carbide lower faces offer superior protection against abrasive sand.
• Tsurumi's original Oil Lifter maintains a stable lubricating environment for the shaft seal at low oil volumes.
• Miniature thermal protector embedded in the motor winding directly cuts the circuit during excessive heat.
• Watertight cable entry with an anti-wicking block prevents water from entering the motor via conductor strands.
• Compact 50 mm discharge configuration provides stable hydraulic performance for a variety of seawater tasks.
