Mechanical seal support system made by STB

STB seal support systems are designed to keep high process security and are developed to seal products within their emission limits. Because of those requirements, STB developed several different seal support systems. Main task of a seal support system is the cooling effect and a controlled lubrication of the mechanical seal faces. To reach that aim, a controlled flow of the medium (for example water, oil) is necessary, to have a cooling effect on the seal face, since the frictional heat is upcoming. This cooling effect, which will heavily extend the lifetime of a mechanical seal, is increased throughout mechanical seal design, with integrated pumping devices. The seal support system is also having the possibilities to work pressurized. The design and features can vary due to the application it is meant for. These different applications are defined by the American Petroleum Institute. Which mechanical seal support system works for your seal is reviewed in correspondence with our engineering staff.

There are many varieties of support plans in the industry, suitable for every case. These plans are documented in the API 682, by the “American Petroleum Institute”. This Institute describes the newest standards for the sealing industry. In summary a support plan can be designed without pressure (TS-System) by a natural flow of heat- and cooling fluids. A high efficient solution of a mechanical seal support system, can ne a heavy duty barrier fluid unit (NSE-54), which increases the cooling effect at the seal faces and boosts the amount of circulating barrier fluid du to a pump STB offers for every mechanical seal support application the right solution. We have a wide product range, starting off with a standard supply tank (TS-12) for simple tasks and the support of double mechanical seals. For higher heat removals TS Systems with integrated cooling coil, sensors for process tracking, level-, temperature- and pressure control are also available. On the field of barrier pressure/-fluid units, we offer our NSE product range. Our NSE-53 and NSE-54 are available as standard units with short delivery times. These units are individually expandable and are suited for the existing mains voltage. The process parameters are analyzed in one unit.
