Tsurumi 50TM2.75 Titanium Corrosion-Resistant Seawater Pump for Breeding Pond Circulation with Semi-Vortex Impeller

Supplying water circulation for seafood processing and large-scale coastal sumps requires metallurgy that prioritizes liquid purity and structural longevity. This corrosion-resistant pump is configured for handling aggressive saltwater and corrosive industrial runoff without introducing toxic contaminants. Its titanium construction ensures a clean and stable operating environment for marine industries and coastal commercial facilities.

Delivering up to 360 L/Min with a maximum head of 15 m, the 0.75 kW / 415v three-phase induction motor provides stable site water management through a 50 mm discharge bore. This motor utilizes a Direct on Line starting method, ensuring reliable performance during consistent drainage duties. The unit is continuous-duty rated for demanding applications.

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, making it critical for handling liquids with suspended organic matter without risking mechanical failure during intensive service.

Construction utilizes a combination of titanium and engineering resin, supported by dual mechanical seals and a patented Oil Lifter for continuous lubrication. Structural integrity is protected by a circle thermal protector and an anti-wicking cable entry that shields the motor from moisture. The use of non-toxic liquid paraffin as a lubricant makes the pump suitable for sensitive seafood processing and aquaculture.

FEATURES

• Titanium and resin construction provide outstanding corrosion resistance in saltwater environments.
• Semi-vortex impeller design facilitates the displacement of 10 mm solids while reducing mechanical contact and wear.
• High-grade titanium shaft offers excellent chemical compatibility and mechanical strength for continuous service.
• Double-face mechanical seals with silicon carbide lower faces offer superior resistance to abrasion and ingress.
• Tsurumi's original Oil Lifter forcibly supplies oil to the seal faces, ensuring reliability even at low lubricant volumes.
• Internal circle thermal protector directly cuts the motor circuit if excessive heat builds up or an overcurrent occurs.
• Watertight cable entry with an anti-wicking block prevents water from entering the motor via conductor strands.
• Compact 50 mm discharge configuration provides stable hydraulic performance for a variety of marine tasks.
