Submersible pump Wilo-Sub TWU 3.03-05-HS-ECP-B constant pressure with converter 6079400

Submersible pump for stable pressure with converter

The Wilo-Sub TWU 3.03-05-HS-ECP-B submersible pump is an advanced solution for stable water supply, both in residential buildings and irrigation systems. Equipped with an external frequency converter, it provides constant water pressure regardless of the current demand, which translates to user comfort and energy savings. The pump design allows for installation both vertically and horizontally, making it easier to install in various conditions.

Performance and reliability in every detail

This pump is a combination of solid construction and intelligent solutions. Made of high-quality stainless steel (grade 304 – 1.4301) and equipped with a PVC-C impeller, it guarantees long-lasting and trouble-free operation even in difficult conditions. The 0.9 kW motor efficiently converts energy, and protection against undervoltage, overvoltage and short circuit further increase safety. The pump is adapted to work with water containing up to 50 grams of sand per cubic meter, making it an ideal solution for wells of varying water quality.

Key features and applications

• Stable pressure: The integrated frequency converter maintains constant water pressure, eliminating fluctuations caused by changes in consumption. This is particularly important for user comfort and the proper operation of devices using water.
• Versatility: Suitable for water supply from deep wells, tanks and reservoirs, as well as for irrigation and sprinkling gardens.
• Durability: The use of corrosion-resistant materials (stainless steel, PVC-C) ensures a long service life of the pump even in an aggressive environment.
• Safety: Protection against overvoltage, undervoltage and short circuit protects the pump and electrical installation from damage.
• Easy installation: The possibility of vertical or horizontal mounting makes it easier to adapt the pump to specific installation conditions.
• Efficiency: The maximum pump capacity is 6.42 m³/h with a maximum head of 95.21 m – this ensures an adequate water flow even in difficult hydraulic conditions.
• Motor protection: The IP58 degree of protection guarantees the pump's tightness and protection of the motor against moisture and dirt.
• Continuous operation: Suitable for continuous operation at temperatures from 3°C to 35°C.

The Wilo-Sub TWU 3 HS-ECP-B pump is an investment in a reliable water source that will provide comfortable use for years to come. Its advanced functions and solid construction make it an ideal solution for both professional installers and demanding end users.
