Details

The LOWARA DIWA 15T is a heavy-duty three-phase submersible drainage pump designed for handling clean and slightly contaminated water in demanding drainage and dewatering applications. Powered by a 1.5 kW (2.0 HP) motor, it provides a maximum head of approximately 20.6 metres and can deliver up to 420 L/min (25.2 m³/h). The hydraulic performance curve shows that the pump maintains substantial flow even at higher operating heads, making it suitable for high-volume drainage duties. The DIWA series uses corrosion-resistant stainless-steel construction and is designed to pass small suspended solids. The DIWA 15T can handle particles of approximately 8 mm, making it suitable for slightly dirty water rather than sewage or heavily contaminated wastewater. Its IPX8 submersible motor, Class F insulation and silicon-carbide mechanical sealing system are designed for reliable continuous operation in submerged installations.

It is ideal for wastewater transfer, drainage, sump pits, dewatering, construction sites, commercial buildings, and light industrial water discharge. This product supports consistent operation, practical handling, and long-term use across demanding working environments.
