Double seal, compact design, balanced, depending on the direction of rotation of the shaft, multi-spring. The BPD seal requires the use of a drilling fluid or barrier fluid installation. Sealing to EN ISO 21049 (API 682): Type A, Category 2 or 3, System 2 or 3, Configuration 2CW-CW or 3CW-FB.
General purpose mechanical seal for the petrochemical and chemical industries. Designed to work with such media as propane-butane, ethanol, acetone, cumene, without mechanical impurities and contamination with abrasive particles. BPD seals prevent the emission of harmful process emissions into the environment due to the use of in-line sealing system acc. API 682 type 2 (tandem) with a cooling and separating liquid system and a non-pressurized tank.
– high resistance to deformation caused by high pressure and temperature,
– low emission of volatile substances into the environment,
– seal connections ensure operation with systems according to API 682.
