Tsurumi 50TMA2.75 Titanium Automatic Seawater Pump for Breeding Pond Circulation with Semi-Vortex Impeller

Automating coastal dewatering and supply for marine industries requires metallurgy that prioritizes liquid purity and structural longevity. Combining titanium construction with automatic level control, this pump is configured for handling aggressive saltwater and corrosive industrial runoff without manual oversight. Its corrosion-resistant construction and integrated control ensure a clean and stable operating environment for marine research and coastal commercial facilities.

Performance reaches up to 360 L/Min with a maximum head of 15 m, driven by a 0.75 kW / 415v three-phase induction motor. Automatic start-stop operation optimizes site dewatering efficiency while protecting the motor against dry-running. This unit is continuous-duty rated for stable performance through a 50 mm discharge bore.

The semi-vortex impeller manufactured from glass-fiber reinforced technopolymer enables 10 mm solids passage while creating a whirlpool effect that keeps debris away from the impeller vanes. This design minimizes mechanical wear and reduces the risk of clogging. The configuration is critical for handling liquids with suspended organic matter without risking mechanical failure during automated industrial service.

Construction utilizes high-grade titanium and engineering resin wetted parts, supported by a titanium shaft for superior chemical compatibility. Sealing integrity is provided by a double-face mechanical seal isolated in an oil chamber featuring a proprietary Oil Lifter. Protection is reinforced by a circle thermal protector and an anti-wicking cable entry block that protects the motor from moisture incursion.

FEATURES

• Integrated level control facilitates automatic operation and unattended management of coastal sumps.
• Titanium and resin construction offer outstanding corrosion resistance for saltwater and marine water transfer.
• Semi-vortex impeller configuration enables the passage of 10 mm solids while reducing mechanical wear.
• High-grade titanium shaft provides exceptional chemical compatibility for long-term service in marine sumps.
• Tsurumi's patented Oil Lifter technology keeps seal faces lubricated even if the oil level is low.
• Circle thermal protector built into the motor housing proactively interrupts the circuit during thermal overload.
• Non-toxic liquid paraffin is used as the lubricant, making the pump safe for seafood processing.
• Watertight cable entry with an anti-wicking block prevents moisture from wicking into the motor housing.
