North Ridge Pumps has created a self-priming pump from duplex stainless steel to replace submersible pumps in seawater cooling applications. The previous system included three submersible pumps, which suffered from corrosion and frequent maintenance issues due to their mild steel construction.

The new pump, designed for a 5-6 m suction lift and capable of delivering over 240 m³/h, is pontoon-mounted and features a baseplate-mounted priming pump. It is protected with C5 marine coating to withstand corrosive seawater conditions. The design addresses seal failures and operational challenges faced by the prior pumps.
