WQ Submersible sewage pump

Heavy-duty submersible non-clog sewage pump engineered for continuous handling of wastewater that contains large solids and long fibers. The compact, motor-pump unit shares a common shaft and is separated by an oil-filled isolation chamber and a mechanical-seal assembly for reliable, long-term operation in demanding wastewater applications.

Key features

• Robust construction in cast iron or stainless steel to suit corrosive or abrasive environments.
• Wide-flow impeller available in single-channel or double-channel designs to minimise clogging and pass large solids and fibrous material.
• Volute casing paired with the optimized impeller for high hydraulic efficiency and reduced risk of blockage.
• Double mechanical seal in series using hard, corrosion-resistant tungsten carbide faces for extended seal life and wear resistance.
• Oil isolation chamber with leakage probe: detects seal failure/water ingress and signals the control system to protect the motor.
• Motor stator available with Class B or Class F insulation for thermal reliability.
• Replaceable wear (seal) ring at the pump inlet to restore clearances and maintain hydraulic efficiency over the unit life.

Protection & control

• Supplied with a full protection pump control cabinet (optional/standard configuration) that can monitor and protect against leakage, phase loss, short circuit, motor overheating and overload.
• Designed for safe, unattended operation with built-in electrical and mechanical safeguards.

Serviceability & installation

• Short overall length and compact structure simplify mounting in sumps and stations.
• Replaceable wear parts and straightforward access to the mechanical seal reduce maintenance time and lifecycle cost.
• Multiple impeller and material options allow configuration for specific site requirements.

Typical applications

• Municipal and residential sewage lift stations, urban sewage treatment plants
• Industrial wastewater discharge with high solids or fibrous content
• Construction site dewatering, mining, and irrigation
• Hospitals, hotels and commercial buildings sewage handling
• Biogas digesters and other agricultural effluent systems
• Also suitable for clean water and certain corrosive media when configured with appropriate materials

Available options include material selection (cast iron or stainless steel), single- or double-channel impellers, and control/protection accessories. Units are intended for B2B buyers specifying dependable, maintainable pumps for heavy-duty wastewater duties.
