15665
Introducing the LEO 150WQ180-11-11/4, a robust submersible sewage pump engineered for demanding wastewater drainage applications across industrial, commercial, and municipal environments. Built on decades of LEO's proven pump technology, this WQ series submersible pump excels in factory drainage, construction site dewatering, residential sewage treatment stations, and countryside irrigation systems where reliable solid-handling performance is essential.
Constructed with a durable PN6 standard pump body featuring hose coupling capability, the 150WQ180-11-11/4 combines copper-wound motors with IP68 enclosure protection to withstand continuous submersion up to 10 meters in challenging wastewater environments. Its versatile design accommodates solids up to 80mm in diameter while maintaining stable operation across pH levels of 4 to 10, making it ideal for mixed sewage streams, methane pool drainage, and municipal wastewater treatment infrastructure where robust construction and corrosion resistance are non-negotiable requirements.
