Drainage pump Wilo Initial Waste 16-11, 3 bar, 10980 l/h, h. 9m, deep 5m, cable 10m, 0.75kw
Features
The free-flow impeller with 20 mm free passage handles liquid containing larger solids without rapid clogging. This setup suits pumping water from basements, pits or sumps with moderate to significant contamination.
The pump housing in polypropylene and impeller in glass-fiber reinforced PA6-GF30 withstand contact with aggressive media and mechanical stress. Stainless steel shaft and motor housing protect against corrosion during prolonged submersion.
The motor is cooled by the pumped liquid, while built-in bimetallic thermal protection and automatic reset prevent overheating during extended operation or dry running in S3-25% mode. Double NBR shaft sealing and oil-filled chamber reliably isolate the electrical parts from water ingress.
The integrated float switch controls liquid level for automatic on/off cycling without constant supervision. This configuration fits stationary installation in sumps or portable use in basements, pools or construction sites.
The 10 m H07RN-F cable with 3×1 mm² cross-section features sealed entry and a CEE 7/7 plug for quick connection to household power. Operating pressure up to 3 bar enables lifting water to 9 m or horizontal transfer over longer distances.
