in a pump P&ID i have found this reads "this equipment shall be installed in a curbed area"..
could anyone explain me what is a curbed area? what protections and precautions should i take in account for the pumps?
What this means is that the pump might leak a little bit from seals and hence you should build a very small wall - a curb - around it( approx 75mm high) so that you can contain any runnoff into the oily water drain. Sometimes you build pumps with a drain plate which does the same thing, but usually gets clogged with dirt and leaves etc.
A curb is the small concrete thing on the side of a road to separate the tarmac where vehicles go from the pavement (sidewalk) where pedestrians go.
My motto: Learn something new every day
Also: There's usually a good reason why everyone does it that way
