Tsurumi 80TM23.7 Titanium High-Head Seawater Pump for Marine Drainage with Semi-Vortex Impeller

Intensive seawater transfer and large-scale drainage for marine research facilities require metallurgy that withstands aggressive coastal corrosion. This marine-duty pump provides a robust technical solution for handling corrosive industrial liquids in demanding factory sumps. Its specialized titanium construction delivers long-term durability where standard iron or aluminum equipment would succumb to rapid oxidation.

Delivering up to 900 L/Min with a maximum head of 26 m, the 3.7 kW / 415v three-phase motor provides stable hydraulic performance for high-pressure dewatering across varied site conditions. This 2-pole dry-type induction motor is rated for continuous duty through an 80 mm discharge bore. The high output allows for effective liquid transfer in deep sumps where significant vertical lift is required.

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 and is essential for maintaining reliable flow when managing liquids with suspended matter in industrial marine sumps. The hydraulic layout ensures stable efficiency during intensive operation.

The wet end combines 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

• Titanium and resin construction ensures outstanding corrosion resistance for aggressive marine research duties.
• Semi-vortex impeller configuration facilitates the passage of 20 mm solids while reducing wear on internal components.
• High-pressure performance reaching a 26 m max head for intensive vertical industrial drainage duties.
• Double-face mechanical seal with SiC lower faces provides superior protection against abrasive coastal sand.
• Patented Oil Lifter technology keeps seal faces lubricated even if the oil volume falls to low levels.
• Circle thermal protector built into the motor housing proactively interrupts the circuit during thermal overload.
• Non-toxic liquid paraffin lubricant makes the pump safe for aquaculture and marine research environments.
• Watertight cable entry with an anti-wicking block prevents moisture from entering the motor via conductor strands.
