Between the maximum diaphragms of the state-of-the-art lacquer and the corlus of the inlet (suction) and outlet (pressurized - room) chambers.

The design of split diaphragms is becoming more complicated, due to the presence of rail elements. The presence of a socket for replacement makes it hard and increases the possibility of mutual displacement of both diaphragms, which reduces the need for their production and assembly. Because of the knowledge of the crypt's labyrinths, they do not need to be used for the assembly of the space, which will also complicate the assembly. - 2 -

The presence of monolithic diaphragms has made it possible to have a tough concept of the statistic elements of the pack. This ensures the consistency of the statistic elements of the 5th package and makes it possible to have the smallest gaps in the labyrinth seals, which increases the efficiency. The efficient operation of the labyrinth seals and the monolithic concept of diaphragms reduces the energy consumption for internal flows and increases the life expectancy of 10 prices.
