GW Sewage Pump

Product Overview
GW inline sewage pump combines imported overseas technology with local pump application features, representing next-generation sewage pumping equipment with prominent energy savings and anti-clog/anti-tangle capabilities. Features proprietary impeller geometry and upgraded mechanical seals for superior solids handling with single or dual-channel impeller design mirroring constant-diameter bent pipeline for excellent flow capacity.
Key Features
- Wide-flow anti-clog hydraulic construction enabling exceptional solids passage: handles fibrous debris up to 5 times pump bore and solid particles reaching 50% of pump diameter
- Optimized hydraulic layout with matched drive motor delivering superior efficiency and remarkable energy savings
- Hard-faced tungsten carbide mechanical seals providing outstanding abrasion resistance for continuous safe operation beyond 800 hours
- Compact footprint enabling convenient relocation and straightforward field installation
- Motor safeguarded against overload across full rated head range with coaxial pump-motor configuration
- Aligned inlet and outlet on horizontal centerline with matching flange sizes for simplified installation
- Single or dual-channel impeller ensuring excellent solids handling capability
- Modular construction with flexible mounting options reducing pumping station footprint
- Premium hydraulic efficiency minimizing overall project investment
