North Ridge Pumps Develops Duplex Stainless Steel Self-Priming Pump for Seawater Cooling
North Ridge Pumps has designed a high-flow self-priming pump made from duplex stainless steel to replace submersible pumps used for seawater cooling. The new pump will provide a suction lift of 5-6 meters and a flow rate of over 240 m³/h. The previous submersible pumps faced operational issues, including frequent maintenance and corrosion due to mild steel components. The new pump features C5 marine coating for enhanced corrosion resistance in marine environments.

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.
