The Industry Standard for Compact Drainage Pumps

Renowned for its tough build and consistent output, the Tsurumi LB-480 is ideal for:

🏗️ Construction site dewatering
🚧 Civil engineering and groundwork projects
💧 Utility maintenance and drainage
🏠 Domestic flood control and basement water removal

Its compact, lightweight design allows for easy handling in tight spaces, while its heavy-duty build ensures it keeps working when other pumps give up.

The Tsurumi LB-480 models incorporate a dual position outlet port, which allows the user to position the outlet hose horizontally or vertically to suit their changing requirements on site and prevent the hose from kinking.

Key Features & Benefits:

✅ Robust Submersible Design – Operates fully submerged for efficient water removal
✅ Built for Dirty Water – Handles water with sand, silt, and debris with ease
✅ Compact & Portable – Just 10.4kg – easy to transport and deploy
✅ Double Mechanical Seal – Superior durability and extended pump life

A combination of a rubber pump chamber, rubber wear plate and a urethane vortex impeller provides excellent wear resistance in site water applications that contain sand and silt in suspension, thus maintaining performance and reliability in the long term.

The Tsurumi LB-480 submersible pumps utilise a 403 stainless steel shaft that is fitted with an ultra hard-wearing twin mechanical seal (inboard: silicon carbide-silicon carbide) which runs in an oil chamber that has a patented oil lifter to maintain seal lubrication during operation in any position. This feature, combined with the water and air cooling route to the top outlet, allows the pump to operate for extended periods with little or no water.

With a proven track record on job sites around the globe, the LB-480 features Tsurumi’s signature oil-lifter technology, ensuring continuous lubrication and protection of internal components – even in dry-running conditions.

This pump is built to last, with a hardened shaft, wear-resistant materials, and a thermal motor protector to prevent damage during extended use.

Considered the hire industry standard, earlier models of the Tsurumi LB-480 have been used in this trade since the mid-70s.
