4.1.3 Seal
Different methods are used for the seal to the fluid and the motor compartment:
ƒ Version "G": two separate mechanical seals
ƒ Version "K": two mechanical seals in a block seal cartridge made of stainless steel
Leakage from the seal is caught in the sealing chamber or leakage chamber:
ƒ The sealing chamber accommodates any possible leakage of the seal on the fluid
side.
This sealing chamber is filled with medicinal white oil ex works.
ƒ The leakage chamber accommodates any possible leakage of the seal on the motor
side.
The leakage chamber is empty ex works.
CAUTION!In the case of motors without an additional leakage chamber, the leak-
age from the seal on the motor side is taken up in the motor!
