    Since the flow causes sliding abrasion at a low angle of incidence in the piping, the rubber that can be suggested for this application is a low durometer hardness (40 Shore A) natural rubber. For lower flow rates at ranges of 1200 L/min up to say 4000 L/min, a hard rubber or a semiebonite rubber can be used since the abrasive wear of the finely meshed particles in this case will be negligible.
