PS Range of Purging Systems

The Type “PS” or Purging Strainer is a completely autonomous in-line self-cleaning strainer. It utilizes a wedge wire basket as its straining component, from 50 micron upwards. The strainers autonomy comes from the fact that it will self-clean the wedge wire basket and purge the waste at pre-set intervals. The strainer will also purge to waste when it detects that the differential pressure is too high and the system needs to be to cleaned. This can occur when dirt loading is not uniform or there is periodic high dirt loading from operations. The cleaning of the screen is done mechanically, which causes the debris to collect in the bottom of the strainer. The debris or dirt collected at the bottom is then purged out through an automatic valve at the bottom of the strainer to waste. The system being on-line at all times through these cycles, utilizes the operational pressure to force the dirt out through the purge valve. The unit self-cleans while in operation, with minimal pressure loss, allowing production to continue without interruption.
