Submersible pump Wilo-Sub TWU 4-0444-C DM 6049355

Submersible pump for wells and water supply

The Wilo-Sub TWU 4-0444-C DM is a reliable submersible pump designed for efficient water extraction from deep wells, tanks, and other sources. Its multi-stage impeller design provides high performance and pressure, making it an ideal solution for both domestic and professional water supply systems. The pump is also suitable for boosting water pressure and irrigation.

Construction and application

This pump is designed to operate in submerged conditions, ensuring quiet and efficient operation. Made from high-quality materials, including stainless steel (housing) and PVC-CPE (impeller), it guarantees long-lasting reliability even in harsh conditions. The use of corrosion and abrasion-resistant materials allows for pumping water containing small amounts of sand – up to 50 g/m³. It is important to remember that the pump is not intended for pumping water with long-fiber or abrasive contaminants.

Key features and benefits

• High efficiency: The pump's maximum flow rate is 6 m³/h, and the maximum head is as high as 285 meters. This allows for efficient water delivery even from very deep wells.
• Durable construction: The housing made of stainless steel 304 (1.4301) guarantees corrosion resistance and long service life. The PVC-CPE impeller further increases the pump's durability.
• Motor protection: Insulation class B and thermal motor protection ensure safe and reliable operation of the device.
• Easy installation: The pump has a 1 ¼ inch (32 mm) internal tapered BSPT-Rc (ISO 7-1 / EN 10226-1) gas threaded discharge connection, making it easy to integrate with the existing hydraulic installation. The length of the pump and motor is 750 mm, and the immersion depth can reach 200 meters.
• Safety: Protection class IP68 guarantees complete sealing and protection against immersion and dust, allowing for safe operation in harsh environmental conditions.
• Three-phase power supply: The pump operates with a rated voltage of 400 V and a frequency of 50 Hz, requiring connection to a three-phase network with a power of 4 kW and a rated current of 10 A. It has a connection cable with a plug for easy electrical installation.
• Optimal operation: At a nominal flow rate of 3.666 m³/h, it achieves a head of 1962.32 kPa, ensuring optimal performance in typical applications.

The Wilo-Sub TWU 4-0444-C DM pump is a solid solution for anyone who needs a reliable water source from a deep well or tank – both for installers looking for proven components and end-users expecting trouble-free access to clean water.
