For professionals on construction sites, farms or busy workshops, reliable dewatering is essential to keep work flowing smoothly. The Tsurumi LB-480 submersible pump has become a trusted standard in the UK hire and drainage sectors and for good reason. Compact, robust and built to handle challenging conditions, it delivers consistent performance when it matters most.
Here’s why the LB-480 is the pump that professionals rely on day in, day out.
Slim Yet Supremely Tough Design
At just 10.4 kg (12.5 kg packed), the Tsurumi LB-480 slides into tight spaces and even fits through an 8″ pipe opening. But its compact size isn’t a compromise- it’s built like a tank.
It features a urethane semi-vortex impeller, wear plates and a rubber pump chamber, engineered to withstand abrasive debris like sand and silt without sacrificing performance. This kind of design ensures longevity, even under constant use in harsh site environments.
Built for Pro-Level Reliability at Low Water Levels
One of the LB-480’s standout features is its top discharge outlet, a clever engineering touch that actively cools the motor even at low water levels. This allows for continuous duty operation and extended dry run capability- features that help avoid costly damage.
Ultra-Durable Seals and Shaft Assembly
Pulled around by tough hydraulic systems, submersible pumps need rock solid internal protection. The LB-480 delivers with:
- A 403 stainless-steel shaft
- Dual silicon carbide mechanical seals housed within an oil-filled chamber (thanks to Tsurumi’s patented oil-lifter for continuous lubrication)
- Impeller and wear plates engineered for high abrasion resistance
These components add up to a pump that stays reliable through challenging water conditions and rough job site handling.
Enhanced Cooling and Thermal Protection
To protect against motor burnout, the LB-480 includes thermal motor protection. Its design, combining water and air cooling via the top discharge, ensures the pump stays cool, even during extended operation in low-water conditions.
High Flow, Solid Performance
Despite its light and compact form, the LB-480 delivers powerful performance:
- Flow rate: Up to 225 L/min
- Max head: Around 11 m
- Solids handling: Up to 6 mm
- Multiple voltage options (110 V or 230 V), plus manual or auto startup versions with float switch
This capability makes it ideal for pumping out contaminated or sediment heavy water quickly and efficiently.
Engineered for Heavy-Duty Use
The LB-480’s durability and simplicity make it a go-to tool on-site. It’s:
- Lightweight and easy to transport
- Tough enough to survive the rigours of day to day use
- Backed by a 3-year guarantee from Henry Pumps
Its reputation doesn’t lie- many hire fleets still rely on the LB-480 more than a decade after its initial release.
Why Choices Matter: Manual vs Auto Float Versions
Manual (standard) LB-480: Simple push button operation- reliable and straightforward.
Auto model (LB-480A): Equipped with electrode-based float level control plus timer- ideal for unattended use or low-maintenance setups.
