Wilo-Sub TWI 5-SE-904EM water pump 4104131

Submersible pump for clean water – a reliable power source

The Wilo-Sub TWI 5-SE-904EM is an efficient and reliable submersible pump designed for pumping clean water from tanks, wells or cisterns. The construction from corrosion-resistant materials guarantees long-term operation even in difficult conditions. It will be suitable for both home installations and professional applications where a continuous water supply is required.

Construction and application

The pump is fully submersible, multi-stage and self-priming. Equipped with a standard suction basket, it effectively draws water from depths of up to 17 meters. Its construction based on stainless steel ensures durability and resistance to external factors. Designed for continuous operation, with a maximum number of operating cycles of 40 per hour. This makes it ideal for supplying water to households, irrigation systems or industrial processes.

Key features and benefits

• Durability and resistance: Made of high-quality stainless steel (304), which ensures corrosion resistance and long pump life.
• Efficiency: Provides a nominal flow rate of 9.52 m³/h and a maximum efficiency of 16.07 m³/h, allowing for efficient water supply to various installations.
• High pressure: The maximum head is 46.73 meters, which allows pumping water to significant heights or through long sections of pipelines.
• Safety: It has an IP68 protection class, which guarantees tightness and safety of use even when fully submerged. It is also equipped with a thermal motor protection.
• Ease of use: Supplied with a 20-meter power cable and a connection box with a mains plug – ready to connect and start.
• Sand protection: The maximum sand content in the pumped water is 50 g/m³, which minimizes the risk of pump damage in the case of poorer water quality.
• Versatility: Adapted to work with a voltage of 230 V (single-phase) and a frequency of 50 Hz – compatible with most electrical installations.

Additional information: the motor power is 1.5 kW, and the average operating temperature is in the range of 5 to 40°C. The motor speed is 2810 revolutions per minute, providing optimal pump efficiency. The outlet connection complies with ISO 7-1 / EN 10226-1 standards (conical BSPT-Rc internal gas thread) facilitates installation and integration with the existing hydraulic installation.
