According to Andrew J. Beall, president of Flowserve’s flow solutions division, the GTSP seals consume at least 10 times less energy than traditional liquid dual seals.
The seals are pressurized with dry steam or nitrogen using bi-directional wavy face topography. This creates a gas-film barrier between the seal faces, helping to eliminate seal face wear, minimize fouling, increase long-term equipment reliability, and lower gas consumption.
Flowserve says the seals are easier to install and maintain than liquid barrier seals. The new seals can eliminate the energy requirements from circulating, cooling and churning a liquid barrier, while creating significantly less heat generation and torque at the seal faces.
