Tosaki TSK550-SW Submersible Pump with Float Switch 550W 0.75HP 1-Phase 220V 2 Inch

Tosaki TSK550-SW Submersible Pump with Float Switch, 500W Motor, 1-Phase 220V System, 2-Inch Discharge
An industrial-grade submersible pump designed specifically for draining wastewater, contaminated water, or water with diluted sewage (suffix code SW - Sewage/Waste Water). Powered by a high-output 550W (equivalent to 0.75 HP) motor compatible with a 1-phase 220V AC electrical system, drawing 4.2A of operating current. The outer casing and impeller system are constructed from premium-grade, extra-thick cast iron, offering superior resistance against abrasion, corrosion, and impacts from sediment and debris in wastewater. The motor housing is made of aluminum to quickly dissipate heat from the internal winding assembly, supporting long continuous duty operations. This sewage pump is equipped with a large 2-inch discharge port, delivering a head performance of 12 meters along with a maximum flow rate capacity of up to 300 liters per minute or 18 cubic meters per hour (Q). The unit features an inlet opening and pump base engineered to allow debris and sludge to pass through the impeller easily without clogging, accompanied by an industrial-grade mechanical seal system that completely prevents water from leaking into the motor chamber. Ideal for draining effluent in wastewater treatment systems, small-scale flood drainage, or general construction sites. This specific model code (TSK550-SW) comes configured with an automatic float switch to control water levels and protect the motor from damage caused by dry running.

Features
- 550W (equivalent to 0.75 HP) drive motor compatible with standard 220V household power systems, delivering high torque and stable operation with a 4.2 A current
- Built-in automatic float switch controls pump operation based on water level, preventing motor burnout from dry running
- Impeller system and suction inlet designed to effectively drain wastewater containing sludge, sediment, and sewage without clogging
- Large 2-inch discharge port allows maximum and rapid evacuation of sediment-laden wastewater.
- Discharge performance delivers a consistent head of 12 meters, ideal for pushing sewage up from underground sump pits or treatment tanks
- Delivers a maximum discharge flow rate of up to 300 liters per minute, meeting the demands of urgent drainage applications
- Maximum flow rate calculated hourly is 18 cubic meters per hour (Q), handling high-volume flood drainage tasks
- Heavy-gauge aluminum motor housing enhances heat transfer and rapidly dissipates heat from the coil windings
- Pump casing exterior and impeller system made of high-quality cast iron, rugged and resistant to wear from dilute chemicals and waste sludge
- Internal mechanical design and motor insulation engineered for continuous duty operation in heavy-duty applications.
- Resists ambient temperatures up to 40°C and can handle pumping liquids with temperatures up to 60°C
- IP68 water and dust protection rating, safe for continuous long-term submerged operation in wastewater throughout its service life

Applications
- Drainage and wastewater treatment: suitable for pumping trapped drainage, wastewater in holding tanks, and sewage in treatment systems of buildings, residences, or small industrial plants
- Drainage in construction and agriculture: used for transferring thin muddy water and floodwater mixed with soil sediment in excavated pits, construction jobsites, or aquaculture ponds
- High-volume fluid circulation: suitable for applications requiring high wastewater flow rates at medium elevations to divert water into subsequent treatment stages
