Dichtomatik's standard shaft seals are designed to function in applications where the operating pressure is 0 to 7 psi. For applications where the operating pressure is above 7 psi, a pressure seal will need to be used. If a standard shaft seal were to be used in a pressure application, the seal would be deformed due to the pressure being applied to the flex section of the seal. This deformation would lead to an increase in the contact between the seal and the shaft causing an increase in temperature and shaft wear. For this reason, pressure seals are standard shaft seals with a specially modified flex section design. The design of the flex section is dependant upon the amount of pressure that is present in the application. Dichtomatik's E style pressure seals are designed to function in applications where the operating pressure is 10 to 30 psi. E style pressure seals are designed so that the I.D. of the metal case is bent into the flex section of the primary sealing lip. By having the metal case in the flex section of the sealing lip, the seal can operate in higher pressure applications without the lip deforming.
