Wear increases rapidly when the particle size increases. The life of the
pump parts can be extended by choosing the correct materials of
construction.
Sharp angular particles cause about twice the wear of rounded particles.
Austinetic manganese steel is used when pumping large dense solids
where the impact is high.
