Warranty: Manufacturer’s Warranty
The Tsurumi HS2.75S is a single-phase manual submersible portable drainage pump built for demanding 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. 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
