Submersible pump Wilo-Sub TWU 4-0405-C EM 6049337

Submersible pump for wells and water supply

The Wilo-Sub TWU 4-0405-C EM is a multi-stage submersible pump designed for efficient water extraction from wells with a diameter of 4 inches (110 mm / 125 mm) and tanks. It is suitable for both domestic installations and irrigation or water pressure boosting systems. The pump design allows for installation in both vertical and horizontal positions, increasing installation flexibility.

Performance and reliability in every detail

This pump offers a maximum capacity of 6 m³/h and is able to lift water to a height of up to 33 meters. Made of high-quality stainless steel (grade 304 – 1.4301) and polypropylene (PP), it ensures durability and corrosion resistance, even in harsh conditions. The impeller made of PVC-CPE guarantees abrasion resistance, and the built-in non-return valve minimizes the risk of damage. This makes the pump reliable and requires minimal maintenance.

Key features for professionals and users

• Resistance to impurities: The pump can handle water containing up to 50 grams of sand per cubic meter, which is important when drawing water from wells with varying quality.
• Universal power supply: Available in a single-phase 230V version, making it easy to integrate with existing electrical installations.
• Safe operation: It has a protection class of IP68, which means complete protection against immersion and dust – an ideal solution for underwater operation. Additionally, insulation class B ensures electrical safety.
• Easy installation: Equipped with a connection cable with a plug, simplifying connection to the electrical network. The discharge connection is a tapered BSPT-Rc (ISO 7-1 / EN 10226-1) internal gas thread with a diameter of 1 ¼ inch (32 mm).
• Efficient hydraulics: The multi-stage hydraulic design ensures high pump efficiency and optimal operating parameters at different lift heights.
• Maximum number of operating cycles: The ability to perform up to 20 operating cycles per hour makes the pump suitable for applications requiring frequent starting and stopping.
• Operation in a specific temperature range: Designed to operate at temperatures from 3°C to 30°C, ensuring its reliability throughout the year.

The Wilo-Sub TWU 4-0405-C EM pump is a solid solution for anyone who needs a reliable source of water from a deep well or tank. Its robust construction and high performance guarantee long-lasting, trouble-free operation for many years.
