Pressurized Flushing for Double Mechanical Seal Systems

When using a back-to-back mechanical seal, it is necessary to provide a sealing water supply unit for the seal. For such a system to operate correctly, the sealing pressure applied to the mechanical seal must be at least 2 bar above the pressure prevailing in the suction housing. Furthermore, it is necessary to be able to control the volume of flow in the seal chamber. The pressure and flow monitoring system is mounted onto the pump.
