Submersible pump Wilo-Sub TWU 4-0418-C EM 2950692

Submersible pump for wells and tanks – a reliable water source

The Wilo-Sub TWU 4-0418-C EM submersible pump is a multi-stage device designed for efficient water intake from deep wells, cisterns and other tanks. The pump design allows for installation in both vertical and horizontal positions, increasing installation flexibility. This is a solid solution for both professionals involved in plumbing installations and individual users looking for a reliable water source.

Performance and reliability in every detail

This pump is distinguished by its high efficiency – up to 6 m³/h – and its ability to lift water to a height of up to 120 meters. Made of high-quality stainless steel (grade 304), it is corrosion-resistant and ensures long-term operation even in difficult conditions. The built-in check valve prevents water backflow, and floating impellers minimize the risk of damage caused by the presence of sand in the water – the tolerance is as high as 50 g/m³. The 1.5 kW motor is powered by 230V, and its cooling is done by the flowing water, which ensures stable operation.

Design and application

The Wilo-Sub TWU 4-0418-C EM pump has been designed with ease of installation and maintenance in mind. It is equipped with a connection cable with a plug, which facilitates connection to the electrical installation. Thanks to its compact size (length 500 mm), it finds application even in limited spaces. The intended use of the pump includes not only the supply of drinking water, but also increasing the pressure in existing installations and lowering the water level in tanks. Protection class IP68 guarantees tightness and safety of operation even with complete immersion to a depth of 200 meters.
