## Long description

The Submersible pump Omnigena WQ 15-7-1.1 400V 1.1 kW for wastewater and drainage is a compact, electrically driven pump designed for continuous submerged operation in drainage, sewage and surface runoff applications. Equipped with a 1.1 kW three-phase motor, this Omnigena WQ series unit is intended to handle dirty water containing typical solids found in construction dewatering, basement draining and agricultural or municipal wastewater removal. The pump is built for installation directly in liquid and transfers water from collection points, pits and sumps to discharge lines.
Advantages
The Omnigena WQ 15-7-1.1 combines robust motor power with a design that tolerates suspended solids and abrasive particles commonly present in drainage and sewage. Its three-phase 400V motor delivers stable performance under load and supports continuous operation where reliable dewatering is required. The pump’s compact submerged construction reduces the need for additional housings or external priming, simplifying installation and maintenance in tight spaces.
Suitable for
 Site dewatering and construction pits
 Basement and cellar drainage after flooding
 Municipal and agricultural wastewater transfer
 Surface runoff and stormwater removal
 Temporary installation in sumps and collection tanks
Key specifications

 Application type: submersible wastewater and drainage pump
 Installation: submerged operation in liquids
 Fluid handled: dirty water, sewage and surface runoff containing common solids

How to use
Install the Omnigena WQ 15-7-1.1 fully submerged in a stable sump or pit with adequate support to prevent contact with the bottom sediment that could accelerate wear. Connect the pump to a compatible three-phase 400 V power supply through appropriate circuit protection and follow local electrical codes. Fit suitable discharge piping and secure any cable entries to prevent water ingress. Start the pump briefly to verify the correct rotation and flow direction; observe the pump during initial operation for abnormal vibration or noise. Regularly inspect the pump exterior and discharge for blockages and ensure the power and control elements are in proper condition.
Usage recommendations
Use the pump for liquids with solids typical of drainage applications and avoid continuous pumping of highly abrasive or fibrous materials that could shorten service life. Where heavy solids or stringy debris are expected, consider pre-screening or a dedicated solids-handling model. Ensure electrical protection and thermal overload devices are in place and perform periodic inspections to clear accumulated sediment and maintain impeller clearance for stable hydraulic performance.
