Anything with cast iron in it has a short life near the sea. Salt air alone starts the rust; add salt spray or brackish groundwater in the pit and an ordinary sewage pump corrodes within a season or two. For a coastal villa, a jetty toilet block or a small marina, that means replacing pumps far too often.
The 50GNWQ15-7-1.1S is the compact stainless answer. It’s precision-cast SS304 throughout, so the salt-laden environment doesn’t eat it, and at 15 m³/h and 7 m head on 1.1 kW through a 50 mm outlet it’s sized right for a home or small facility. It’s still a full cutter pump — the 48 HRC alloy disc shreds the wipes and sanitary waste that block small pits — with a heat-treated 3Cr13 impeller behind it.
