Tsurumi 80TMA23.7 Titanium Automatic Seawater Pump for Marine Drainage with Semi-Vortex Impeller

Automating heavy marine drainage and industrial seawater transfer requires a pumping solution with maximum head and integrated control. Designed for unattended operation, this pump is engineered for handling raw seawater and corrosive industrial runoff in demanding coastal factory sumps without manual monitoring. Its specialized titanium construction ensures a long service life in automated marine environments.

Performance reaches up to 900 L/Min with a maximum head of 26 m, driven by a 3.7 kW / 415v three-phase motor. Automatic control ensures the unit activates only when the liquid reaches the sensor, providing energy-efficient dewatering. This motor is continuous-duty rated through an 80 mm discharge bore for intensive applications.

The semi-vortex impeller manufactured from glass-fiber reinforced technopolymer enables 20 mm solids passage while creating a centrifugal whirlpool effect that minimizes mechanical contact with debris. This arrangement significantly reduces erosive wear during automated discharge cycles and is essential for maintaining reliable flow when managing liquids with suspended matter in factory sumps.

Construction features high-grade titanium and engineering resin for all wetted parts, supported by a titanium shaft for superior chemical resistance. Sealing is provided by a double-face mechanical seal in an oil chamber featuring Tsurumi's patented Oil Lifter for continuous lubrication. Protection is enhanced by a circle thermal protector and an anti-wicking cable entry block that safeguards the motor from moisture ingress.

FEATURES

• Integrated level control provides automatic operation for hands-free management of coastal dewatering.
• Titanium and resin construction ensures outstanding corrosion resistance for aggressive marine research duties.
• High-pressure performance reaching a 26 m max head for intensive vertical industrial drainage tasks.
• Semi-vortex impeller configuration facilitates the passage of 20 mm solids while reducing wear on internal components.
• Double-face mechanical seal with SiC lower faces provides superior protection against abrasive coastal sand.
• Tsurumi's original Oil Lifter forcibly supplies oil to the seal faces, ensuring reliability even at low lubricant volumes.
• Circle thermal protector built into the motor housing proactively interrupts the circuit during thermal overload.
• Anti-wicking cable entry block uses a molded rubber seal to prevent water from entering the motor housing.
