Wilo-Emu KS 12 D drainage pump 6042087

Dirty water submersible pump – reliable operation

The Wilo-Emu KS 12 D pump is a solid solution for removing contaminated water and sewage. The cast iron construction ensures durability and resistance to mechanical damage, which is crucial in demanding working conditions. The unit is perfect for construction sites, farms, and industry, where effective removal of water containing sand and other contaminants is necessary.

Performance and reliability in detail

This three-phase submersible pump is characterized by high efficiency – up to 27.74 m³/h – and the ability to lift water to a height of up to 13.52 meters. The 1.9 kW (P1) motor provides stable operation even under heavy load. A built-in float switch (not standard, but can be installed) additionally protects the device from running dry, which extends its lifespan. The power cord with CEE M16W plug facilitates connection and ensures safe use.

• Durable construction: The pump body, impeller, and motor housing made of cast iron GG 25 (GJL-250) guarantee corrosion resistance and mechanical damage resistance.
• Efficiency: Maximum flow rate of 27.74 m³/h allows for quick and effective water drainage.
• Immersion depth: The ability to immerse up to a depth of 12.5 meters enables operation in difficult conditions, even in deep excavations or tanks.
• Self-cooling motor: Ensures reliable operation even with intensive use.
• Protection: Protection class IP68 guarantees tightness and protection against environmental influences, allowing operation in a completely submerged state.
• Nominal flow rate (BEP): At a flow rate of 15.61 m³/h, the pump achieves optimal efficiency and minimizes energy consumption.
• Free sphere passage: The diameter of solid particles up to 40 mm allows pumping water with sand, stones and other contaminants without risk of damage to the pump.

Technical specifications for professionals

The Wilo-Emu KS 12 D pump has been designed for demanding industrial and construction applications. The motor operates at a voltage of 400 V and a frequency of 50 Hz, and its insulation class F provides high thermal resistance. The Storz C (DN50) discharge connection facilitates connection to pipes with standard dimensions, and the nominal operating mode S1 means continuous operation without risk of overheating or damage to the device. The impeller material is cast iron GG 25 (GJL-250), which ensures its mechanical strength and resistance to abrasion by solid particles present in the pumped liquid.
