The company announces its need for Supply of FLOWSERVE Kit. The design of the mechanical seal for the pumps installed in BAPCO Upstream oil field are double mechanical seal type due to presence of H2S. Between these two seals is pressurized a buffer liquid which would prevent H2S to come out if inboard mechanical seal failed, meanwhile the second mechanical seal, the outboard seal is holding the pressure. The pressure of the buffer or barrier fluid is higher as the pump discharge pressure, so in case of leak buffer fluid will act as a barrier to prevent pumping liquid contain H2S to come out. To pressurize the barrier fluid between the seal is used an external mobile pump. If the barrier fluid pressure starts decreasing due to inboard seal leak, it will be trigged an alarm to increase barrier fluid pressure. If not done, pump will trip, to avoid H2S gas to come outside pump seal chamber.
