DAB.FEKA - submersible sludge pumps

The DAB.FEKA submersible sludge pumps are designed for continuous operation in wastewater applications. These pumps are suitable for pumping sewage and raw water containing particles or long fibres, with a maximum throughput of up to 108 mm. They are commonly used in industrial and construction environments where wastewater with solids needs to be efficiently managed. The pumps operate within liquid temperature ranges of 0°C to +55°C and can be submerged up to 20 m. They are available in a range of flow rates from 3 to 780 m³/h and discharge heads up to 28 m.

Constructed with cast iron EN GJL 200 for durability, these pumps feature silicon carbide mechanical seals and asynchronous motors with thermal protection. They are supplied with a 10 m H07RN-F power cable and are compatible with control systems for protection and monitoring. Installation is typically vertical and portable, with optional lifting devices available for larger models.

How to choose

• Assess the required flow rate and head to match the pump’s operating range (e.g., 3 to 780 m³/h and up to 28 m discharge).
• Ensure compatibility with the system’s voltage (e.g., three-phase 400 V/50 Hz for certain models).
• Verify the maximum solid particle size in the pumped liquid to select a model with the appropriate throughput (e.g., 62 mm for FEKA 2500/2700 or 80–108 mm for FEKA 6000/8000 series).
• Confirm the need for additional control systems, such as float switches or external protection units, depending on the model.
• Check the required installation method (e.g., fixed or portable) and ensure the pump’s flange type (e.g., UNI 1.092 PN 6) matches the system.

Frequently asked questions

What is the maximum immersion depth for DAB.FEKA sludge pumps?
Most models are rated for a maximum immersion depth of 20 m, with some models suitable for depths up to 10 m.

Can these pumps handle aggressive liquids?
No, the pumps are designed for non-aggressive wastewater only. Aggressive liquids may damage the cast iron components and seals.

What type of power cable is supplied with the pump?
The standard power cable is 10 m in length and made of neoprene (H07RN-F), suitable for submersion and flexible installation.
