Salt-water and marine-grade pumps for the South African coastline
Richards Bay. Durban. Saldanha. Cape Town's harbour. Salt air, chloride-laden water and continuous duty cycles destroy standard cast-iron pumps in months. Tunnel Fox sources duplex, super-duplex, and naval-bronze pumps engineered for decades of marine service.
About salt-water resistant pumps
Salt-water pumps handle seawater, brackish water, brine, and chloride-rich process fluids. Standard cast-iron and 316 stainless fail quickly under chloride attack — selection requires duplex (UNS S31803), super-duplex (UNS S32750), naval bronze, or bronze-fitted construction matched to the chloride concentration and temperature.
