Features
The flushing unit of the FUS series consists of a distributor, an inline filter, a needle valve and a pressure gauge. Optionally available with thermometer and/or flow transmitter or switch. The unit is used to control the flushing to mechanical seal. The flush unit continuously supplies the mechanical seal with a flush medium from an external source. This plan is usually combined with a throttle disc, which creates a higher pressure in the stuffing box space, which is used to separate the product from the sealing chamber.
