JOHNSON PUMP Seawater / Impeller pump for Volvo Penta / Perkins / Mercedes / Nanni

The life of a seawater and impeller pump is limited, even if maintenance such as replacing seals and impellers is carried out regularly. The reason for this is corrosion, which is caused by the constant water exposure to the pump even when the engine is at a standstill, as well as erosion caused by the high flow speed of the seawater inside the pump housing.
Often small but steadily increasing water leaks, usually at the bottom of the housing, are signs of a 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 loss, we now offer seawater/impeller pumps for the most common types of engines on the market.
