QW Pump

Product Overview
QW Type Non-Clogging Submersible Sewage Pump. All performance indicators of this product meet international standards for similar products, featuring high efficiency, energy saving and a unique structure. Since its launch, it has been well received and praised by users for its distinctive design and reliable quality.
Key Features
- Large-flow passage anti-clogging hydraulic design significantly enhances impurity passage capacity, effectively passing fibrous materials up to 5 times the pump caliber and solid particles with diameter of approximately 50% of pump caliber
- Rational design with properly matched motor delivers high efficiency and remarkable energy-saving performance
- Double-series mechanical seal made of hard wear-resistant tungsten carbide ensures durable and reliable operation for over 8,000 hours
- Compact structure with small volume, easy mobility and simple installation - no pump house required, can operate submerged, greatly reducing project costs
- Oil-water probe in pump oil chamber detects water ingress when mechanical seal fails, triggering protection signal to safeguard the pump
- Optional fully automatic safety protection control cabinet monitors leakage, electric leakage, overload and over-temperature conditions to ensure reliable and safe pump operation
- Dual-rail automatic coupling installation system provides great convenience for pump safety and maintenance, eliminating need for workers to enter sewage pits
- Guarantees motor operates without overload within applicable head range; motor can adopt water-jacket external circulation cooling system for safe operation in waterless (dry) conditions
- Two installation methods available: fixed automatic coupling installation and mobile free installation to meet different application requirements
