Tsurumi 50TMA2.4 Titanium Automatic Seawater Pump for Marine Transfer with Semi-Vortex Impeller

Automating marine effluent management for seafood processing and industrial plants requires a pumping solution with integrated control and outstanding corrosion resistance. Engineered for hands-free seawater pumping, this pump is designed for managing seawater and corrosive industrial runoff in factory sumps without manual monitoring. Its specialized titanium construction ensures durability in automated environments where manual oversight is not feasible.

Delivering up to 300 L/Min with a maximum head of 12 m, the 0.4 kW / 415v three-phase motor provides stable performance through a standard 50 mm discharge bore. The automatic functionality ensures the unit activates only when required to maintain factory site water levels, optimizing energy efficiency. This motor is continuous-duty rated for demanding applications.

The semi-vortex impeller manufactured from glass-fiber reinforced technopolymer enables 10 mm solids passage while creating a centrifugal whirlpool effect that minimizes mechanical contact with debris. This arrangement significantly reduces erosive wear during automated cycles and is essential for maintaining reliable flow when managing liquids with suspended matter in factory sumps.

Structural integrity is maintained through a titanium shaft and resin frame, with dual mechanical seals isolated in an oil chamber featuring an Oil Lifter. Protection is enhanced by a circle thermal protector built into the motor housing and an anti-wicking cable entry block that protects the motor from moisture. The unit utilizes non-toxic liquid paraffin as a lubricant, making the pump safe for automated seafood processing.

FEATURES

• Automatic operation via level control facilitates hands-free management of marine effluent systems.
• High-grade titanium and resin construction provide superior corrosion resistance in aggressive coastal factory sumps.
• Semi-vortex impeller configuration enables efficient 10 mm solids handling while reducing hydraulic friction.
• Tsurumi's original Oil Lifter maintains a stable lubricating environment for the shaft seal at low oil volumes.
• Dual-face mechanical seals with silicon carbide (SiC) lower faces provide high-grade protection against abrasion.
• Internal circle thermal protector directly cuts the motor circuit if excessive heat builds up or an overcurrent occurs.
• Liquid paraffin is used as the motor lubricant, ensuring the pump is safe for seafood processing.
• Watertight cable entry with an anti-wicking block prevents moisture from entering the motor through capillary action.
