double mechanical seal

The working mechanism of a double mechanical seal. the double seal uses a couple of primary seals and a buffer fluid area or barrier in between the two layers. each primary seal has two parts; a soft and narrow stationary face and a hard and wide rotating face.
The double-mechanical seal construction consists of two self-sufficient seals mounted inside the seal chamber outer surface of the pump, which is flushed with a self-sufficient water supply at a flow rate of around two to four gallons per hour (least amount) and a load is less superior to the highest expected to function pressure of the pumped solution.
Hard seal faces for abrasive service, carbon vs. ceramic for simple water (or anti-freeze in the case of automotive applications). carbon vs. silicon carbide for most applications to reduce energy consumption and provide long life. for critical applications double mechanical seals are usually recommended.
Double seals. a double seal consists of two sets primary sealing surfaces with the space in-between the two seals filled with a compatible pressurized fluid called the barrier fluid. this barrier fluid/space may be monitored to detect performance of the assembly.
