WQD-S Stainless steel submersible sewage pump 220v

A compact, all‑stainless submersible sewage pump engineered for reliable handling of wastewater and corrosive liquid media in commercial, municipal and light industrial installations.

Key features and benefits

• Precision-cast stainless steel construction for corrosion resistance, reduced weight and easier maintenance compared with cast-iron designs.
• Unique single- or double-channel impeller design increases open passage capacity and allows passage of long fibers up to approximately five times the pump diameter, reducing clogging risk.
• Robust sealing system: fluororubber double-face mechanical seal plus fluororubber radial O‑ring to protect the motor and internal components in harsh environments.
• Built-in motor protection (overheat and current/overload protection) to prevent damage from overload or excessive temperatures.
• Designed for submerged operation—eliminates the need for a dedicated pump room and can lower installation and civil costs.
• Flexible configuration options: anti-corrosion cable assemblies, PTFE mechanical seals, and high‑temperature component packages available to meet specific site requirements.
• 220 V single‑phase electrical configuration; float switch control can be fitted for automatic level control.

Typical applications

• Building drainage and basement sump pumping
• Municipal sewage and stormwater outlets
• Residential developments and multi‑family buildings
• Industrial wastewater: factories, food & beverage, pharmaceuticals
• Aquaculture and seawater/saltwater pumping (where stainless steel is suitable)
• Sites with long-fiber wastewater, general corrosive liquids and solids-containing effluent

Installation & maintenance notes

• Submersible design simplifies installation — drop into wet wells or sumps; consult local electrical codes for single‑phase wiring and protection.
• Routine inspection of seals, cable entry and impeller passage recommended to maximise service life and prevent blockages.
• Available customization for harsher media or elevated temperatures; specify required seal materials and cable options at order stage.
