How The Tsurumi LB-800 Compares To The LSC1.4S And HSZ2.4S
Contractors and facility managers evaluating Tsurumi's submersible pump lineup now have three options depending on the job. Here's the honest comparison:
| Feature | Tsurumi LSC1.4S, Low-Level, 1/2 HP ($613) | Tsurumi HSZ2.4S, Trash Pump w/ Agitator, 1/2 HP ($500) | Tsurumi LB-800, High-Capacity, 1 HP ($833) |
|---|---|---|---|
| Primary Purpose | Draining flat surfaces down to 0.4 in. residual water | Pumping water containing sand, solids, and debris | High-volume general dewatering for construction and rental applications |
| Motor | 1/2 HP | 1/2 HP | 1 HP, the most powerful of the three |
| Flow Rate | Up to 45 GPM | Up to 53 GPM at 5 ft. of head | Up to 80 GPM, significantly higher volume |
| Max Head | 39 ft. | 39 ft. | Up to 59-60 ft. |
| Cable Length | 20 ft. | 20 ft. | 50 ft., longer reach for deeper or more distant setups |
| Design | Semi-open ductile iron impeller for low-level drainage | Built-in agitator prevents clogging from settled sand/sediment | Slimline design fits into an 8" pipe/caisson for confined spaces |
| Discharge | Not specified in this comparison | 2" angled discharge | 2" top discharge for maximum motor cooling and extended dry-run capability |
| Automatic Operation | Not specified | Built-in automatic float switch | Manual (automatic float switch versions available separately) |
| Best Suited For | Near-complete drainage of flat surfaces without a sump | Debris-laden water needing hands-free, clog-resistant operation | High-volume dewatering in confined spaces like caissons and deep excavations |
Why The Tsurumi LB-800 Is Worth The Investment
This isn't just a submersible pump, it's built with a slimline design that fits into an 8" pipe or caisson while delivering up to 80 GPM of flow and 59-60 ft. of shut-off head, giving contractors and rental operations the highest-capacity option in the Tsurumi lineup for confined, deep, or high-volume dewatering applications.
The LB-800 specifically addresses the needs of contractors and rental operations handling high-volume dewatering in confined spaces, deep excavations, or general construction site drainage where the smaller LSC1.4S or HSZ2.4S wouldn't provide enough flow or reach.
Maximum Flow And Reach In A Confined-Space Design. With up to 80 GPM of flow, a 50 ft. cable, and a slimline profile that fits into an 8" pipe, this pump delivers significantly more volume and reach than the smaller LSC1.4S or HSZ2.4S, all while still fitting into tight caissons and confined excavation spaces.
Built For High-Capacity, Continuous-Duty Operation
The top discharge design maximizes motor cooling efficiency, enabling continuous duty operation at low levels
The wear-resistant semi-vortex urethane impeller and wear plates ensure durability under demanding dewatering conditions
The slimline design allows effortless installation into 8" pipes or caissons for confined-space applications
Engineered For Long-Term Reliability
The dual Silicon Carbide mechanical seal provides longer operational life than standard single-seal designs
The oil lifter provides lubrication of the seal faces to extend service life
Extended dry-run capability reduces the risk of motor damage if water levels drop unexpectedly
Real Savings
Higher flow rate and head capacity reduce the need for multiple smaller pumps on larger dewatering jobs
The 50 ft. cable reduces the need for extension cords or repositioning power sources on deep or distant setups
A 2-year limited manufacturer warranty reduces the risk of unexpected repair costs
Free shipping and no sales tax through Summit Forge Supply keeps the total cost down compared to buying elsewhere and paying tax and freight separately
The Bottom Line Contractors and rental operations handling high-volume dewatering in confined spaces like caissons or deep excavations can't get that combination of flow, reach, and slimline fit from the smaller LSC1.4S or HSZ2.4S. The Tsurumi LB-800 is built with a slimline 8"-pipe-compatible design, up to 80 GPM of flow, and a 50 ft. cable, so it delivers the highest capacity in the Tsurumi lineup covered here. For anyone handling large-volume or confined-space dewatering as a regular part of the job, this is the pump built to keep up with the water.
- Slimline design allows it to fit seamlessly into 8-in. pipes, enabling easy transport and installation in confined spaces
- Durable construction features a wear-resistant urethane impeller and wear plates for extended service life in harsh conditions
- Reliable performance is achieved with dual silicon carbide mechanical seals that provide superior protection against abrasion and contaminants while reducing maintenance needs
- Top discharge design maximizes motor cooling efficiency for continuous duty operation at low water levels
- Extended dry-run capability reduces the risk of overheating and ensures consistent performance in demanding applications
- Compact and lightweight design makes the pump easy to handle and transport, saving time and effort on the job
- High-capacity operation delivers efficient and consistent dewatering for construction, rental, and other challenging environments
- Patented oil lifter provides seal face lubrication down to 1/3 of the normal level and extends seal life by ten times
- Urethane rubber-coated impeller is more abrasion-resistant and lasts up to three times longer than a cast iron impeller
