Wilo-Sub TWI 5-505EM-FS water pump 4144941

Submersible water pump – a reliable source of clean water

The Wilo-Sub TWI 5-505EM-FS is an efficient and reliable submersible pump designed to supply water from own intakes, wells or tanks. The construction based on durable materials, such as stainless steel, guarantees long life and corrosion resistance. This model finds application both in households and in irrigation systems and in industry.

Construction and application

The pump is characterized by a compact design and a diameter of 5 inches, which allows its installation in wells with a diameter of at least 6 inches. It is equipped with a hydraulically cooled motor, which allows it to operate even when partially submerged. The FS version has a built-in float switch, which protects the pump from running dry and protects the motor from damage. This allows the pump to be used in applications requiring automatic on and off, e.g. in drinking water supply systems. The robust construction with materials resistant to sand allows pumping water with a small content of solid particles – up to 50 g/m³.

Key features and benefits

• Durability and reliability: The pump body and impeller made of stainless steel ensure corrosion resistance and long life of the device.
• Efficiency: The maximum pump capacity is 9.29 m³/h, and the maximum head is 56.48 m, which allows for effective water supply even from deep wells.
• Dry-running protection: The integrated float switch automatically turns off the pump in the absence of water, protecting the motor from damage. This is a particularly important solution for installers who can avoid costly warranty repairs.
• Easy installation: The pump is supplied with a power cable 20 m long and a safety rope, which facilitates its installation and use.
• Versatility: Suitable for pumping clean water from wells, tanks and other sources. Can be used in both domestic and industrial installations.
• High quality workmanship: The 0.9 kW motor ensures stable pump operation even under heavy load. Insulation class F guarantees safe use.
• Sand resistance: The pump is adapted to work in water containing up to 50 g/m³ of sand, which increases its durability and minimizes the risk of failure in difficult operating conditions.

The Wilo-Sub TWI 5-505EM-FS pump is an investment in a reliable water source for years to come – both for demanding end users and professional installers looking for proven solutions.
