Coastal and low-lying municipal stations have a corrosion problem inland ones don’t: saltwater intrusion. Brackish groundwater seeps into the network, and tidal areas push seawater back up the lines, so the pump sits in a salt-laden mix that corrodes cast iron far faster than ordinary sewage would.
The 100GNWQ80-10-4S is a stainless station pump for that setting — precision-cast SS304, moving a useful 80 m³/h at a low 10 m head on 4 kW through a wide 100 mm outlet, which suits the high-volume, low-lift profile of a coastal collection station. The 48 HRC alloy cutter handles the municipal wipe-and-rag load that any town sewer carries.
Where salt is in the water, stainless pays for itself in pumps you don’t have to keep replacing. Specifying for a coastal network? Tell us the duty and we’ll size it. sales@haquanpump.com
