Structural Description
The QW(WQ) series clog-resistant submersible sewage pump integrates motor and pump components, separated by an oil isolation chamber and mechanical seals, forming a compact electromechanical unit with a shared rotor shaft. Key features include:
Signal Cable – Connects to a comprehensive control cabinet for protection against leaks, phase loss, short circuits, overheating, and motor overload.
Stator – Utilizes Class B or F insulation.
Leakage Sensor – Installed in the oil chamber to detect seal failure and trigger system protection.
Mechanical Seal – Dual tandem seals with tungsten carbide for durability and extended service life.
Impeller – Single or double-channel design for superior debris/fiber passage, minimizing clogging.
Pump Casing – Optimized for high efficiency with the impeller.
Wear Ring – Replaceable at the volute to maintain peak efficiency when wear occurs.

Operating Conditions
1.Medium temperature ≤60°C, specific gravity 1.0-1.3kg/dm³, pH 5-9.
2.For pumps without internal cooling systems, ≤50% of the motor may extend above liquid level.
3.Operate within specified head range to prevent motor overload. For full-range operation, special order required.
4.Running current must not exceed motor's rated current.
