Wilo-Sub TWI 5-306DM water pump 4104123

Submersible water pump – a reliable water source for your home and farm

The Wilo-Sub TWI 5-306DM pump is a solid and efficient device designed for drawing water from wells, boreholes or tanks. Made of stainless steel, it guarantees long-lasting and trouble-free operation even in difficult conditions. Designed for both domestic and agricultural or industrial applications, it provides stable water pressure and high flow rate.

Construction and operating parameters

This submersible pump with a diameter of 5 inches (127 mm) is designed to be submerged to a depth of up to 17 meters. The durable construction with a housing and impeller made of stainless steel (grade 304 – 1.4301) ensures resistance to corrosion and mechanical damage. The 0.75 kW motor operates on a 400 V power supply, and its efficiency reaches up to 5.91 m³/h, allowing water to be lifted to a height of up to 64.46 meters. This makes the pump suitable for potable water supply systems, garden irrigation and industrial processes requiring a stable water supply.

Advantages for the installer and end user

• Durability and reliability: Made of high-quality stainless steel, it ensures a long service life of the pump, minimizing the risk of failure and repair costs.
• High efficiency: Maximum efficiency of 5.91 m³/h allows for quick filling of tanks and effective irrigation.
• Resistance to contamination: The pump is adapted to work in water containing sand – the maximum sand content is 50 g/m³.
• Easy installation: Equipped with a connection cable with a plug, it facilitates connection of the pump to the electrical installation. The outlet connection with a diameter of 1 ¼ inch (32 mm) with an internal BSPT-Rc (ISO 7-1 / EN 10226-1) thread ensures compatibility with most piping systems.
• Safety: The IP68 protection class guarantees complete tightness of the pump, protecting it from the effects of moisture and dust, even when submerged in water. Insulation class F provides additional safety of use.
• Versatility: Suitable for both deep wells and retention tanks, making it a versatile solution for various needs.
• Work optimization: The C characteristic of the protective switch allows for safe starting of devices with an induction motor that generate high starting currents – this is important for installers designing electrical protection systems.

The Wilo-Sub TWI 5-306DM pump is an investment in a reliable water source that will provide comfortable use for many years.
