Drainage pump Wilo Drain TMW 32/11 16000l/h, height 12m, depth 1m, cable 4m, 0.55kW
Features
The vortex mechanism combined with an open multi-channel impeller efficiently pumps liquid containing sand or gravel particles without rapid clogging. A 10 mm free passage ensures uninterrupted operation even with moderate water contamination.
The pump housing and suction strainer are made of composite PP-GF30 material, resistant to corrosion and mechanical stress in wet conditions. The impeller in PPE/PS-GF20 withstands contact with abrasive inclusions without deformation.
The stainless steel motor is cooled by the pumped liquid, while built-in bimetallic thermal protection prevents overheating during extended operation or dry running in S3-25% mode. Double shaft sealing (radial + mechanical face) and an oil-filled chamber reliably protect the electrical components from water ingress.
The integrated float switch controls liquid level for automatic on/off cycling without constant supervision. This setup suits stationary installation in sumps or portable use in basements, pits, pools or construction sites.
The 4 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 2 bar enables lifting water to 12 m or horizontal transfer over longer distances.
