The life of a seawater pump is limited, even if maintenance activities such as replacement of sealing and impeller are performed regularly. The reason for this is corrosion, which is caused by the constant condensation of the pump even if the engine is at a standstill, as well as material removal due to erosions as a result of the high flow speed of the seawater inside the pump housing.
Often small but steadily increasing leakages, usually at the bottom of the housing, are signs of a seawater pump's demise. At that point, you should think about a replacement.
In order to assist skilled skippers in carrying out their own repairs without causing a total financial loss, we have now offered seawater pumps for the most common types of engines on the market since 2015. Dimensions, connection widths, flow rates and shaft diameters can be found in the table. There you will also find information on which pump is suitable for which manufacturer/motor type. We have seawater pumps (impeller pumps) from the most popular manufacturers, such as Volvo Penta, Yanmar, Bukh, Perkins and Vetus.
