Type 6 mechanical seal range
CLICK HERE ← Back to Mechanical Seal Types.
Type 6 seals (also known as Type 16 or Type B04) are very common seal for small house pressure pumps. They are a non-pusher type seal as they seal against the shaft at the back of the mechanism and use a bellows to seal in the pressure. 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. To make them economical though they use a spring to assist the bellows. This makes them ideal for dirty and abrasive water conditions. They are also pressure rated to a maximum of 1000kpa.
Type 6 seals are only available in imperial sizes, we have Type 6 seals IN STOCK HERE in our webshop.
