Johnson cooling water pump:
After DV36 serial No. 1051 the outer dimensi ons of the Johnson cooling water pump have
been changed and the pump has been par tly simplified at the same ti me, as e.g. the carbon
ring stuffing box has been left out.
The type and the technical data of the pump and height of the cam in ca se of direct seawater
cooling and indirect freshwater cooling respectively are the same for the new pump as for the
one previously used. Further the impeller is the same as that used on the previous pu mp. The
new pump can be used by excha nging the previous one if the pipe connections are changed
too.
