Wilo-Sub TWI 5-504EM water pump 4144950

Submersible pump for clean and dirty water – reliable water supply

The Wilo-Sub TWI 5-504EM pump is a robust and efficient device designed for pumping clean water and water containing sand, ideal for supplying water from your own intake, wells or tanks. The construction based on durable materials, such as stainless steel, guarantees a long service life even in difficult conditions. The pump is used both in households and in agriculture or industry.

Construction and application

The Wilo-Sub TWI 5-504EM is a submersible pump with a diameter of 5 inches, made of stainless steel. The multistage design provides high efficiency and pressure, allowing effective lifting of water to significant heights – up to 44 meters. The maximum pump capacity is 9.2 m³/h. It is designed for continuous operation, with the possibility of up to 40 operating cycles per hour. Thanks to the IP68 protection class, it is completely resistant to immersion and groundwater action. The use of a motor with its own cooling system allows it to operate even when partially submerged.

This pump will be useful in many situations:

• Drinking water supply: Provides access to clean water from wells or boreholes.
• Irrigation: Ideal for irrigation systems for gardens, agricultural crops or lawns.
• Water transfer: It will be useful for pumping water from retention tanks or deep wells.
• Fire protection systems: It can be used as an element of systems for increasing water pressure in fire protection installations (after proper configuration).
• Construction and earthworks: For removing water from excavations and foundations.

Key features and benefits

• Durability and reliability: Made of high-quality stainless steel (housing, impeller, shaft), which ensures corrosion resistance and long-term operation. The material of the impeller and housing is stainless steel 304 (1.4301).
• Efficiency: The 0.75 kW motor generates a nominal flow rate of 4.984 m³/h at a head of 289.98 kPa (2.9 bar).
• Resistance to impurities: The maximum sand content in the pumped water can be as high as 50 g/m³, making it ideal for use in dirty conditions.
• Safety: The IP68 protection class guarantees complete tightness and safe use in a water environment. Insulation class F provides additional protection for the motor against overheating.
• Easy installation: Equipped with a connection cable with a plug to facilitate connection to the electrical network (230 V). The outlet connection is a tapered BSPT-Rc (ISO 7-1 / EN 10226-1) internal gas thread with a diameter of 1 ¼ inch (32 mm).
• Versatility: Can be used for both clean and dirty water containing sand.
• Maximum working pressure: Up to 10 bar - ensures safe operation of the installation.

The Wilo-Sub TWI 5-504EM pump is an investment in a reliable water source for years to come!
