50WQ15-40-5.5 5.5kW High Head Sewage Pump 40m | For Underground Cavern Drainage

The WQ series is a submersible sewage pump built to move water that is not clean. The range is filled out across 2-, 4-, 6- and 8-pole motors, so the same platform does two very different jobs: 2-pole models spin at 3,000 rpm and turn speed into head — up to 60 metres — from casings of 2 to 8 inches, while 4-, 6- and 8-pole models slow down and open out, moving up to 5,000 m³/h at heads as low as 4 metres. Because it runs from 0.75 kW to 400 kW with discharge of 2 to 24 inches, a buyer picks the duty first and the model second, rather than taking whatever the supplier happens to stock. An optional agitator stirs settled sludge back into suspension, so a pit empties to the floor instead of leaving a bed of solids behind. A cutter version reduces fibrous material before it reaches the impeller, and a stainless line covers aggressive media. Typical duties: basement sumps, construction dewatering, sewage lift stations, farm slurry pits, flood transfer and plant drainage.
