Warranty: Manufacturer’s Warranty
The Tsurumi LSP1.4S is a single-phase portable self‑priming residue drainage pump incorporating a submersible motor, designed for fast removal of standing water down to floor level via the supplied 5m suction hose and attachment. Its flow‑thru design provides maximum motor cooling efficiency, allowing continuous operation at low water levels and extended dry‑run capability. The pump features dual inside mechanical seals (upper: ceramic + carbon; lower: SiC + ceramic) isolated in an oil chamber with an Oil Lifter for enhanced lubrication, an anti‑wicking cable entry, a siphon breaker to prevent reverse‑flow, and a miniature thermal protector (MTP) for overheat protection. This Australian version is rated for 50Hz operation (240V supply) and is well‑suited for construction, mining, industrial, and emergency dewatering across Australia and other 50Hz regions.
Suitable Applications
- Final clean‑up after standard dewatering
- Draining shallow pits, tanks, and basins
- Flood response and emergency water removal
- Commercial and residential clean‑ups
- Tight‑access areas where larger pumps won't fit
- Mining and construction site dewatering
