The details that decide how long a sewage pump lasts are easy to overlook on a spec sheet. GNWQ pumps are specified to survive: bolts and lifting rings in SUS304 stainless steel (not ordinary steel that rusts away in a wet pit), a built-in motor protection device, and a graphite–silicon-carbide mechanical seal.
Materials that hold up
• Cast iron HT200 casing and HT250 pump body for a rugged, stable structure
• SUS304 stainless bolts and lifting ring — no rusted-solid hardware at service time
• Graphite–SiC mechanical seal (joint-venture or imported seals optional)
• Built-in motor protection guards against overload and burnout
Applications: long-life municipal duty, corrosive farm effluent, continuous industrial wastewater, hard-to-service deep pits
