Monitoring Pump Discharge Pressure in Slurry Lines

In applications where positive displacement pumps are used for pumping abrasive slurries, it is imperative to measure pump discharge pressure in case the system encounters a blockage. The pump is normally capable of generating very high pressures in excess of the operating limits of the piping system. As a safety measure, normally a rupture disk system is employed as a preventative measure. However, if the disk ruptures, the slurry sprays out into the surrounding area. In the case of sewage sludge or harsh chemicals, this could mean a very expensive cleanup.
