Featured in the photo below left is the pump cutwater which has been part blasted and steam cleaned, now revealing the river salts which are the black areas in the casting. Subsequently these will be removed by further steam cleaning and blasting until the casing is to a SA2.5 Swedish Standard of cleanliness, with a least a 75-micron profile before coating with two coats of Belzona 1341 (Supermetalglide) as shown below centre and below right.
