Boosterpump

Just a small part of a coolingwater boosterpump of unit EC 20.There are three of these pumps, when the unit is on the grid, two pumps are running.
Now we have to empty the coolingwatersystem for the repair of a defective valve.
The seawater has taken its toll; some parts are a bit rusty.
A small flow of water is leaking along the shaft....
