Submersible sewage pump SEV.65.65.09.Ex.2.50b 0.9 kW 3x400 V 96115124

Submersible sewage pump for demanding applications

This three-phase Grundfos SEV.65.65.09.Ex.2.50B submersible pump with a power of 0.9 kW is designed for reliable sewage pumping, even those containing solids. Made of durable cast iron, both the motor housing and the pump body, it ensures long life and corrosion resistance in harsh environmental conditions. The pump is designed to operate in explosive atmospheres, making it an ideal solution for the chemical industry, refineries or wastewater treatment plants.

Design and application

The SEV pump with a SuperVortex impeller is a robust unit designed for operation in wet and dry pits. Its design allows for efficient pumping of wastewater with solid content up to 65 mm, making it indispensable in municipal management and industry. The cooling system ensures stable operation even with intensive use. Explosion-proof design (Ex) guarantees safety in potentially hazardous environments. Therefore, the pump finds application not only in standard sewage installations, but also in places where there is a risk of gas or dust explosions.

Key features and benefits

• Durable construction: Motor housing and pump body made of cast iron GG 20 and GG 25 provide high resistance to mechanical damage and corrosion.

• Efficient SuperVortex impeller: Enables pumping of wastewater with large solids (up to 65 mm) without the risk of pump blockage.

• Explosion-proof design: Ensures safe operation in explosion hazard zones (EEx d IIB T4 and Ex n IIB T4).

• Long power cable (10 m): Facilitates installation and provides flexibility in choosing the mounting location.

• Immersion depth up to 10 m: Allows the use of the pump in deep wells and tanks.

• Dry-running protection: Protects the pump from damage in case of accidental starting without the pumped medium.

• High efficiency: Maximum efficiency of 24.5 m³/h and head of 7.5 m guarantee effective wastewater drainage.

• Insulation class F: Provides high resistance to overheating and extends the life of the motor.

• Voltage 3x400-415 V: Standard three-phase voltage facilitates integration with existing electrical installations.

The Grundfos SEV.65.65.09.Ex.2.50B pump is an investment in a reliable and safe solution for wastewater drainage, which will work in demanding industrial conditions and in municipal installations - ensuring long-term and trouble-free operation for many years of use.
