We keep it sealed


For high efficient turbine performance, it is imperative to have well sealed gaps between the rotors and stators. Improperly sealed gaps greatly increase the risk of steam and pressure losses. Properly sealed gaps result in less turbulence, optimized flows and increased turbine efficiency. This helps to generate more power with the same amount of energy input. PGS provides the best way to seal such loss-generating turbine gaps. That helps you to save money and reduce CO2 emissions. PGS designs, manufactures and supplies the world“s largest range of seal strips for all makes of turbines. Precisely matched caulking wires are used to secure the seal strips to the rotor and turbine housing parts. This ensures that the steam only gets to where it belongs: on the turbine blades!

Our entire product portfolio is available and ready for shipment, so we can ship immediately after we receive your order – regardless of whether you’re ordering small or large quantities.
