Material Pairings and clearances
To minimise the risk of ignition through friction and friction-impact sparks due to possible malfunctions, aluminium/aluminium or
aluminium/brass pairings have been used.
The minimum radial and axial clearances between the impeller and casing should be at least 0.5% of the impeller diameter or a
minimum of 2mm. Inspections should be made during regular maintenance downtime to check the clearances. Methods to carry out
these checks can be seen in the dismantle/re-assembly section.
