WQ Submersible Sewage Pumps

The WQ Series Submersible Sewage Pump is a high-performance, versatile solution designed for demanding wastewater drainage and transfer applications. Engineered with advanced features to handle challenging media, it is the ideal choice for municipal, industrial, agricultural, and commercial wastewater systems.

Key Features & Advantages of WQ Submersible Sewage Pumps

Superior Clog Resistance: Equipped with a unique single or double-vane impeller, this pump ensures smooth passage of large solids, capable of handling fibrous materials up to 5 times the pump's diameter and solid particles up to 50% of the pump's diameter.
Exceptional Durability: The mechanical seal is made from hardened, corrosion-resistant titanium tungsten, guaranteeing safe and continuous operation for over 8,000 hours.
Compact & Cost-Effective Design: With a compact, quiet, and energy-efficient design, the pump operates fully submerged, eliminating the need for a dedicated pump house and significantly reducing construction costs.
Comprehensive Automatic Protection: Integrated features include a high-precision leak detection sensor and built-in thermal protectors in the motor windings. Optional automatic control cabinets provide full protection against leakage, overload, and overheating, allowing safe operation across the entire head range.
Flexible Installation & Control: The pump can be paired with an optional float switch for automatic start/stop based on liquid level. It offers two installation methods: a fixed, guide-rail coupling system for easy maintenance, or a movable free-installation setup.
