Characteristics and performance
The Hallite SRS is a single-acting, low-friction rod buffer seal, designed to be utilized in conjunction with a primary pressure seal. The buffer is designed from proprietary Armorlene® material face ring paired with a specially profiled energizer. The Armorlene® face ring offers low friction and the elimination of stick-slip. High-performance Armorlene® materials, like HLX, provide outstanding wear and extrusion- resistance properties as well as large range of temperature and media compatibility.
The SRS is a pressure buffer seal that protects the primary rod seal from high-frequency pressure spikes in a system. The design allows oil to pass through to the rod seal while holding back pressure spikes. The Hallite SRS also allows pressure to pass back into the system, preventing a pressure trap situation between the rod seal and the buffer seal.
