Type MG1 mechanical seal
Type MG1 seals are widely used in small domestic and industrial high pressure pumps, most commonly the horizontal multistage pumps from Davey, Franklin and others. They are a hybrid pusher /non-pusher type seal that uses an integrated bellows and shaft seal that seals in the pressure at the impellor end of the mechanism. A spring assists the bellows in tensioning the seal face against the stationary and this spring is very strong and has a short stroke. The rotary face is commonly carbon graphite based but can also be available in silicone carbide and tungsten carbide. The stationary face is normally ceramic but can also come in silicone or tungsten carbide. They can handle dirty or contaminated water due to the use of a bellows. They are also able to handle high operating pressures up to 1200kpa (12 Bar). Type MG1 seals are stocked by Rural Pumps in only a couple of common metric sizes but can be ordered in up to 100mm, we have Type MG1 seals IN STOCK HERE in our webshop.
