Tsurumi 50TM2.4 Titanium Corrosion-Resistant Seawater Pump for Marine Transfer with Semi-Vortex Impeller

Corrosive liquid transfer and seafood processing require a pumping solution with high chemical resistance and structural integrity. Designed specifically for seawater service, this pump is engineered for handling seawater and corrosive industrial runoff in demanding coastal factory sumps. Its specialized titanium construction ensures long-term service where standard stainless steel or iron equipment would succumb to rapid oxidation.

Hydraulic output extends to up to 300 L/Min with a maximum head of 12 m, powered by a 0.4 kW / 415v three-phase motor. This induction motor is rated for continuous duty through a 50 mm discharge bore. The Direct on Line (D.O.L.) starting method ensures immediate activation and stable discharge pressure for intensive industrial dewatering.

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. The arrangement significantly reduces erosive wear and is essential for maintaining reliable flow when managing liquids with high concentrations of suspended matter in factory sumps.

Mechanical integrity is supported by a titanium shaft and 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 seafood processing applications.

FEATURES

• High-grade titanium and resin construction provide superior corrosion resistance in industrial saltwater.
• Semi-vortex impeller configuration enables efficient 10 mm solids handling while reducing hydraulic friction.
• Internal circle thermal protector directly cuts the motor circuit if excessive heat builds up or an overcurrent occurs.
• Patented Oil Lifter technology keeps the mechanical seal faces lubricated even if the oil volume falls to low levels.
• Dual mechanical seals with silicon carbide (SiC) lower faces provide high-grade protection against abrasion.
• Liquid paraffin is used as the motor lubricant, ensuring the pump is safe for seafood processing plants.
• Watertight cable entry with an anti-wicking block prevents moisture from entering the motor via capillary action.
• Threaded oval flange discharge allows for secure connection to standard 50 mm industrial drainage lines.
