Submersible pump Wilo-Sub TWU 4-0427-C DM 6049353

Submersible pump for wells and water supply

Wilo-Sub TWU 4-0427-C DM is a three-phase submersible pump designed for efficient water extraction from deep wells and tanks. The construction based on multi-stage impellers ensures high efficiency and reliability, and the solid construction from corrosion-resistant materials guarantees a long service life even in harsh conditions. This is an ideal solution for both domestic and professional water supply systems.

Construction and application

The pump is designed to operate completely submerged, which ensures quiet operation and effective engine cooling. It uses hydraulics with radial or semi-axial impellers with a segmented design, which translates into high pumping efficiency. The use of materials such as stainless steel (pump body) and polypropylene (impeller) in Wilo-Sub TWU 4 pumps ensures corrosion and mechanical damage resistance. It can be mounted both vertically and horizontally - in the case of horizontal mounting, a cooling jacket is required.

• Applications:
  • Water supply from deep wells up to a depth of 200 meters.
  • Irrigation systems for gardens and crops.
  • Rainwater harvesting from cisterns.
  • Industrial water intake systems.

Key features and parameters

The Wilo-Sub TWU 4-0427-C DM pump is characterized by high efficiency and the ability to adapt to various working conditions. The 2.2 kW engine provides stable operation, and thermal protection protects against overload. High sand resistance (up to 50 g/m³) allows operation in contaminated water conditions. Thanks to the IP68 protection class, the pump is completely resistant to immersion and moisture.

• Performance: The maximum pump capacity is 6 m³/h, and the maximum head is 175 meters.
• Power supply: The pump operates at a voltage of 400 V and a frequency of 50 Hz - requires a three-phase connection.
• Material: The pump body is made of stainless steel (304), which ensures durability and corrosion resistance. The impeller is made of polypropylene (PP).
• Connection: It has a 1 ¼ inch (32 mm) tapered BSPT-Rc internal gas thread.
• Safety: Equipped with a motor thermal protection and a power cable with a drinking water certificate.
