Tsurumi 40TMA2.25 Titanium Automatic Seawater Pump for Marine Transfer with Semi-Vortex Impeller

Automated coastal sump drainage in commercial facilities requires a technical solution that combines integrated level control with high seawater resistance. Featuring integrated level control, this pump is engineered specifically for unattended seawater pumping, providing hands-free management of marine sumps. Its corrosion-resistant metallurgy ensures long-term structural integrity in automated environments where manual monitoring is not feasible.

Performance reaches up to 240 L/Min with a maximum head of 9 m, powered by a 0.25 kW / 415v three-phase motor. Automatic start-stop operation ensures the unit activates only when required to maintain site water levels. This motor is continuous-duty rated through a 40 mm discharge bore for stable performance.

The semi-vortex impeller manufactured from glass-fiber reinforced technopolymer enables 10 mm solids passage while minimizing mechanical contact between debris and the impeller. The design significantly reduces erosive wear during automated cycles. The semi-vortex behavior ensures stable hydraulic efficiency while preventing obstruction during intensive commercial seawater transfer.

Structural integrity is maintained through a titanium and resin body, with a titanium shaft for enhanced 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.

FEATURES

• Automatic operation via integrated level control facilitates unattended management of commercial coastal sumps.
• Titanium and resin wetted parts offer superior corrosion resistance against aggressive seawater.
• Semi-vortex impeller design enables 10 mm solids passage while reducing mechanical contact and hydraulic wear.
• High-grade titanium shaft provides exceptional chemical compatibility for long-term service in marine sumps.
• Tsurumi's Oil Lifter forcibly supplies oil to the seal faces even if the lubricant volume falls to low levels.
• Circle thermal protector built into the motor housing proactively interrupts the circuit during thermal overload.
• Non-toxic liquid paraffin lubrication ensures the unit is suitable for automated aquaculture duty.
• Threaded oval flange discharge allows for secure connection to standard commercial coastal drainage lines.
