Tosaki TSK250 Submersible Pump 250W 0.33HP 1-Phase 220V 1 Inch

Tosaki TSK250 submersible pump, 250W motor, 1-phase 220V power system, 1-inch pipe size
Submersible pump or heavy-duty dewatering pump powered by a 250W (equivalent to 0.33 HP) motor, supporting a 1-phase 220V AC electrical system. The external build offers a noticeable upgrade from smaller models, with the pump casing and impeller made from high-quality, extra-thick cast iron for outstanding durability against wear, abrasion, and sediment impact. The motor housing is made of lightweight aluminum that rapidly dissipates heat from the internal windings, supporting rugged, long-lasting continuous operation. This pump model is equipped with a standard 1-inch discharge pipe, delivering outstanding delivery head performance up to a maximum of 15 meters, with a maximum flow rate of 75 liters per minute or 4.5 cubic meters per hour (Q). It features a special-grade mechanical seal that effectively prevents water from penetrating into the motor windings, offering great value and reducing maintenance costs. Suitable for deep well pumping, general stagnant drainage, as well as agricultural and sprinkler irrigation applications.

Features
- Driven by a 250W motor (equivalent to 0.33 HP), supporting standard 220V household voltage for consistent and powerful torque
- Standard 1-inch discharge pipe size (full 1 inch), designed to connect snugly and securely to hoses or PVC pipes
- High head delivery performance with a maximum head of up to 15 meters, ideal for pushing water to high elevations or steep slopes
- Delivers a maximum discharge capacity of 75 liters per minute, enabling fast and efficient water drainage and transfer
- Maximum hourly flow rate of 4.5 cubic meters per hour (Q), accommodating high-volume water pumping and transfer tasks
- Heavy-gauge aluminum motor housing enhances heat transfer and rapidly dissipates heat from the coil windings
- Pump casing and impeller made of high-quality cast iron, rugged and highly resistant to scratching and sediment wear
- Internal mechanical design and motor insulation engineered for continuous duty operation in heavy-duty applications.
- Multi-layer mechanical seal made from carbon, ceramic, and stainless steel, decisively preventing water from entering the motor chamber
- Capable of handling liquid temperatures up to 60°C and operating in ambient temperatures up to 40°C
- IP68 waterproof and dustproof rating, ensuring safe and durable submerged operation throughout its service life.

Applications
- General drainage and wastewater treatment: Suitable for pumping stagnant drainage water, wastewater in holding tanks, small industrial plants, or draining water from flooded excavation pits at construction sites
- Water circulation and garden landscaping: Ideal for medium-sized artificial waterfalls, decorative fountains, or circulating water in fish ponds requiring high head pressure
- Agriculture and irrigation: Suitable for agricultural activities such as flood irrigation, drawing water from ponds or rivers, or feeding spray irrigation sprinkler systems
