Warranty: Manufacturer’s Warranty
The Tsurumi HS3.75S is a single-phase manual submersible portable drainage pump built for demanding high-capacity dewatering applications, delivering the durability of three-phase units thanks to abrasion-resistant wear parts. Its side-discharge spiral casing allows solid matter and debris to pass freely, while the shaft-mounted agitator prevents air lock. With an 80 mm discharge bore, it handles larger flow rates than its 50 mm counterparts. The pump includes dual inside mechanical seals with silicon carbide faces, an Oil Lifter for enhanced seal lubrication, an anti-wicking cable entry, a circle thermal protector (CTP) for overheat and overcurrent protection, and a resin-made stand to protect floor surfaces. This Australian version is rated for 50Hz operation (240V supply) and is well-suited for construction, industrial, and flood response drainage across Australia and other 50Hz regions.
Suitable Applications
- Construction site and foundation dewatering
- Floodwater removal from residential, commercial, and industrial premises
- Site water management and dewatering
- Industrial wastewater and process water drainage
- Sediment removal from sumps and basins
