The screw spindle pump S-VSA 150 is designed to operate in the vacuum. STB GmbH developed a replacement mechanical seal for the pump type S-VSA 150 to take the place of the standard metal bellow seal. Through the use of a group spring the metal bellow can be replaced. The mechanical seal of the type S130 is by this special feature not only economical, it also has a high availability. The seal faces are relieved by their design and offer high operation time, low wear and tear and reduced frictional heat development. Due to the high versatility of the pump specifying the fluid is mandatory to allow the optimization of the materials, especially on the secondary seal.
