AULINK 3853850 sea water pump is a direct-replacement marine pump for Volvo Penta engines featuring a bronze impeller and premium C&U bearings for reliable coolant circulation.

Built to meet marine demands, this AULINK pump combines corrosion-resistant components, careful finishing and full test verification to keep your seawater cooling system operating efficiently.

• Vibration-polished surfaces reduce micro-abrasion
• Unitized mechanical seal design to limit leaks
