FEKA VS 1200 T-NA Submersible Sump Pump - action DAB.FEKA VS

Product detailed description

The FEKA VS 1200 T-NA submersible sump pump is commonly used in industrial and domestic settings where the removal of sewage or slurry water containing solid particles is required. It is suitable for installation in sumps, septic tanks, and other environments where water with suspended solids needs to be pumped away. The pump operates efficiently in both fixed and portable configurations, making it adaptable to a range of site-specific requirements. Installers typically encounter this model in applications involving greywater or blackwater systems, where the presence of organic matter and fibrous material is expected.

When selecting and sizing the pump, the presence of solid particles and the required flow rate are critical factors. The pump is designed to handle water with solids up to 50 mm in diameter, which is particularly useful in systems where macerating or pre-screening is not feasible. The flow rate of up to 32 m³/h and a head of 14 m make it suitable for medium to large installations where high-volume water removal is necessary. The operating temperature range also allows for use in both residential and industrial environments, depending on the type of water being handled.

Technical parameters

The pump’s technical parameters define its suitability for specific applications. The flow rate of up to 32 m³/h and a head of 14 m are essential for determining the pump’s capacity to move water over a given distance. The ability to handle solids up to 50 mm in diameter ensures that the pump can operate without clogging in environments with high particulate content. The operating temperature range of 0 °C to +35 °C for domestic use and 0 °C to +50 °C for other applications allows for flexibility in installation conditions. These parameters are crucial for proper system design and pump selection.

Installation and connection

Installation of the FEKA VS 1200 T-NA requires positioning the pump in a vertical orientation within the sump or tank. The pump is suitable for both fixed and portable use, depending on the application. The supplied 10 m H07 RN–F cable must be connected to a suitable power supply. The single-phase version is equipped with a Schuko plug for direct connection to a standard socket. During installation, it is important to ensure that the pump is fully submerged to prevent motor overheating and to maintain the integrity of the mechanical seals. Common installation mistakes include incorrect orientation, insufficient submersion, and failure to secure the pump properly, which can lead to vibration and premature wear.

Compatibility and accessories

The FEKA VS 1200 T-NA is compatible with standard electrical systems and can be integrated into existing pumping systems with appropriate electrical and hydraulic connections. It is typically used in conjunction with sump pits, control panels, and discharge piping. Additional accessories such as check valves, float switches, and pressure sensors may be required depending on the system configuration. Installers should ensure that all electrical components are compatible with the pump’s voltage and phase requirements.

Technical background for designers

The FEKA VS 1200 T-NA operates using a dry, asynchronous motor that is hermetically sealed and cooled by immersion in the pumped liquid. The cast iron construction provides durability and resistance to corrosion in non-aggressive environments. The impeller is precision cast to ensure efficient flow and minimal wear. The pump is equipped with a double mechanical seal with an oil chamber to protect the motor from contaminants. The integration of the pump into a system depends on the hydraulic and electrical requirements of the installation. Factors such as the depth of submersion, flow rate, and operating temperature significantly affect the pump’s service life and efficiency.

Service and operation

Regular inspection of the pump is recommended to ensure continued performance. Key checkpoints include the condition of the mechanical seals, the integrity of the electrical connections, and the presence of any blockages in the impeller. The pump should be periodically removed for cleaning and inspection, especially in environments with high particulate content. No specific service intervals are provided in the brief, but maintenance should be carried out according to the manufacturer’s technical data sheet.
