The VETUS STM6109B is an original VETUS raw water/seawater pump for certain VETUS marine diesel engines.
Its function is to draw water from outside the boat and circulate it through the engine cooling system. This water removes heat from the system and is subsequently discharged together with the exhaust gases.
It is a mechanical pump driven by the engine itself, not an electric pump. It contains a flexible rubber impeller, which is a maintenance part and should be inspected and replaced periodically.
The STM6109B is identified as a pump for VETUS M2/M3.06/28/29 engines, meaning it is specifically marketed for this engine family.
