Description and operating conditions
The WQ(D)-S series is the heart of the range. Casing and impeller are made of precision-cast stainless steel (304 or 316) and withstand even aggressive media. A double FKM mechanical seal in the oil chamber and an additional outer seal reliably protect the motor against water ingress. High-temperature winding, class F insulation and thermal protection ensure a long service life. With 47 models from 0.75 to 22 kW, the series covers almost every drainage task – from building sumps to municipal pumping stations.
Operating conditions: Medium temperature up to 40 °C (optional up to 100 °C), immersion depth max. 5 m, viscosity 7 × 10⁻⁷ to 23 × 10⁻⁶ m²/s
