ARRANGEMENT-3

The MAFFS has developed API (American Petroleum Institute) 682 seals for the oil and gas industry market. The MAFFS Type A pusher seal is available in Arrangement 1, 2 and 3. An Arrange- ment 1 seal is a single contacting wet cartridge seal with a Throttle bush. Arrangement 2 cartridge seal is the same configuration as the Arrangement 3 seal but is an un-pressurized dual seal where the barrier fluid pressure is kept lower than the seal chamber fluid pressure. The outboard seal will provide back up of hazardous fluids in case of Inboard Seal failure. MAFFS has designed, manufactured and tested to meet API 682 requirement, Type A pusher seal in Arrangement 1 and Arrangement 3 (dual pressurized cartridge seal) for the market. In an Arrangement 3 design the barrier fluid pressure is kept higher than the seal chamber pressure and is designed to handle and contain hazardous and light hydrocarbon fluids. The Inboard seal is specially designed to handle reverse pressure. Outboard Seal is same as Arrangement Seal. With many years of experience in seal design, manufacturing and testing for the industrial market, MAFFS has the experience to solve your sealing problems. Expert Engi-neering provides optimum sealing solutions to meet customer needs.
