Product Name: Double face mechanical seals for Abrasive Fluids


Double mechanical seal arrangement is used to handle toxic, volatile, hazardous or abrasive fluids. In a double seal arrangement, there are two seals with a fluid circulating between them. The fluid that circulates between the seals is called a barrier fluid if its pressure is higher than stuffing box pressure and it is called a buffer fluid if its pressure is lower than stuffing box pressure. The two seal faces are generally installed in one of the three different configurations as shown under.
