Flowserve announces two solutions for compressors: the Aquapac water-lubricated seal for oil-free screw compressors serving green hydrogen, and the Ampliflow T-Boost gas seal booster for dry gas seals. The information below is based on the company's publicly released content, accompanied by technical context compiled by SNS-VN.
Hydrogen used for fuel cells, electronics, or energy storage requires very high purity. Even a small amount of lubricating oil entering the gas can contaminate the product. Therefore, oil-free screw compressors and oil-free seals are of interest.
According to the company, this is the first water-lubricated mechanical seal for oil-free screw compressors. The solution uses ultra-pure water instead of oil or buffer gas, thereby maintaining the purity of hydrogen and aiming for emission-free hydrogen compression.
Dry gas seals require clean and high-pressure gas compared to the seal chamber. During startup or shutdown, the natural pressure difference may not be sufficient, and a booster is needed. According to the company, T-Boost is fully enclosed to prevent gas leakage, has an eddy current-free housing, and reduces heat load, so no additional cooling is required.
