Warranty: Manufacturer’s Warranty
The Tsurumi LSP1.4S is a single‑phase portable self‑priming residue drainage pump with a submersible motor and suction attachment. It is designed to drain water down to floor level, even in shallow flooding or narrow spaces. A siphon breaker mechanism prevents reverse‑flow when the pump stops. The lightweight construction (aluminium alloy and synthetic rubber) ensures easy portability, and the flow‑thru design provides excellent motor cooling at low water levels, allowing continuous operation and extended dry‑run capability. The pump delivers a maximum capacity of 50 L/min and a maximum head of 6.9 m (7.8 m at 60 Hz). Suction and discharge bore are 25 mm (1″), motor output 0.48 kW, 2‑pole, capacitor‑run, 115‑240 V, IP68, dry weight 16.5 kg (excluding cable). The suction attachment comes with a 5 m free‑positioning hose.
Suitable Applications
- Residential, commercial, industrial residual drainage
- Basement sump pump (does not require a sump)
- Decorative waterfalls and fountains
- Construction site dewatering, floodwater drainage, cleaning works
