 | MR80 - Low-Cost Heavy Duty Mechanical Seal be used for general purpose for all industries. It can replace most model of single coil spring, multiple spring and wave spring mechanical seal. Metal bellows is made from SS316L so it is a low-cost metal bellows mechanical seal but high perfomance, robust design and reliable for general applications. It is the most popular metal bellows type mechanical seal. |
 | MR70 – Corrosion Resistant Mechanical Seal be used for all extreme corrosive chemical application. All parts, including bellows, are made of HASTELLOY® C-276*. MR70 mechanical seal has excellent resistance to a wide variety of chemical process environments, including strong oxidizers such as ferric and cupric chlorides, hot contaminated media (organic and inorganic), chlorine, formic and acetic acids, acetic anhydride, seawater and flue gas desulfurization systems. |
 | MR76 – Abrasion Resistant Mechanical Seal be used for abrasive and corrossive media applications. Metal bellows is made of AM350. AM 350 is a semi-austentic precipitation hardenable stainless steel. It is capable of high strength and hardness after heat treatment. It is produced with high melt cleanliness for improved mechanical properties and resistance to fatigue failure. It also has good weldability. |
 | MR9 – High Temperature High Strength Mechanical Seal be used for high temperature application such as refinery, petrochemical and chemical industries. Due to its narrow seal croo section design, it can replace most type of seal that using in most ANSI pumps. Secondary seal are made of graphite foil that can withstand high temperature up to +425 degree C. Bellows is made of INCONEL® 718** or AM350. |
| MR6 – High Temperature Positive Drive Mechanical Seal has more or less the same design as MR9 but positive drive lug is add to provide positive drive that suitable for thermosetting or viscous media applications. It help to extend mechanical seal service life by absorbing excessive torque. Bellows can be made of INCONEL® 718** or AM350. |
 | MS4 – High Temperature High Speed Mechanical Seal is designed to have bellows as stationary seal so it can accomodate high range of shaft speed. It can be used at shaft peripheral speed up to 50 m/s. Bellows can be made of INCONEL® 718** or AM350. |
