Water Pump Mechanical Seal Material

Rings of ceramic carbide carbon or composites of these materials are lapped flat in the range of less than 1 micron on an axial end face.

Water pump mechanical seal material.

The other key aspect of a mechanical pump seal is how to maintain the seal. The load the seal faces receive are engineered into the design of the seal. If your specification calls for this range the pump seal material specification should be changed to epr carbon tungsten carbide tc or epr silicon carbide sic silicon carbide sic. We recommend the epr sic sic material since that seal can handle ph up to 12 5 which gives some wiggle room.

Other mechanical seal hardware which includes shaft sleeves gland rings collars compression rings and or pins. These seals require lighter packing pressure than standard oil and water resistant packing seals so they cause less friction and reduce shaft wear. The faces in a typical mechanical seal are lubricated with a boundary layer of gas or liquid between the faces. The more common end or rotating face mechanical seal designs feature mating faces as the primary sealing elements.

They re made of graphite impregnated aramid fiber and are for use in pumps and valves. Springs single or multiple a metal bellows or just compressed elastomers are used to provide the needed energy to keep pressing the seal faces together.
