Generally speaking, conventional sewage pumps operating submerged underwater inevitably encounter issues such as motor overheating, seal failure, and internal component jamming. However, the WQ series centrifugal pumps are engineered from design to structure with extreme submerged conditions in mind. This makes them ideally suited for fully submerged applications like underground garages, stormwater pumping stations, and chemical plant wastewater tanks, establishing them as the premier choice in submersible sewage pumping.
This pump features a large-channel, clog-free hydraulic design, this equipment significantly enhances medium conveyance capacity. It efficiently transports fibrous materials up to five times its diameter and solid particles approximately 50% of its inlet diameter. Consequently, it is particularly suited for handling wastewater containing particulates and corrosive substances in industries like cement plants, steel mills, power stations, and coal yards, which also minimizes the likelihood of internal blockages. Moreover, to enable prolonged underwater operation, the mechanical seal of this equipment utilizes a novel hard, corrosion-resistant titanium-tungsten alloy material, ensuring safe and continuous pump operation exceeding 8,000 hours. The pump's seal oil chamber incorporates a high-precision, anti-interference leakage detection sensor, while thermosensitive elements are pre-embedded in the stator windings to enable automatic motor protection. For automated monitoring of pump leakage, electrical leakage, overload, and overheating conditions, a fully automated control cabinet can be integrated, significantly enhancing product safety and reliability.
WQ series submersible sewage pump features a cooling water jacket design in its casing, enabling heat to be directly transferred to the surrounding water medium without requiring external fans or pump room ventilation. In other words, even when submerged long-term at the bottom of sewage pits, the pump will not burn out its windings due to inadequate heat dissipation. For extended continuous submerged operation, the pump's flow-through components are constructed from wear-resistant stainless steel, enabling operation in high-salinity, high-chloride environments such as seawater and chemical wastewater.
The key to the WQ series centrifugal pump's ability to deliver media continuously for extended periods in submerged conditions lies in its large flow channels, safety protection features, superior sealing performance, and corrosion resistance. These characteristics enable it to meet delivery requirements under fully submerged conditions.
