Sonic offers a Seal Flushing system that provides improved performance and simplicity above the age-old pressure pot units that resemble something off a world war sub. Instead of using a completely pressurized vessel with a hundred bolts holding together, we offer a simple vessel that is not pressurized and a PD pump that pressurizes the seal chamber by pumping through a adjustable valve that generates pressure. This way, only the seal chamber sees the pressure instead of the entire piped system and vessel. The vessel is jacketed to provide cooling and contains instrumentation such as level sensor and temperature sensor to monitor flushing fluid. These are clean, sanitary assemblies using stainless tubing and sanitary connections.
