Water Pump Mechanical Seal Material

The faces in a typical mechanical seal are lubricated with a boundary layer of gas or liquid between the faces.

Water pump mechanical seal material.

We recommend the epr sic sic material since that seal can handle ph up to 12 5 which gives some wiggle room. Mechanical seals require clean water or other compatible liquid for the lubrication of the seal faces. They re made of graphite impregnated aramid fiber and are for use in pumps and valves. These seals require lighter packing pressure than standard oil and water resistant packing seals so they cause less friction and reduce shaft wear.

The other key aspect of a mechanical pump seal is how to maintain the seal. Highly cost effective and reliable for high volume water systems swimming pools shower pumps central heating irrigation. 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. 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.

The load the seal faces receive are engineered into the design of the seal. Other mechanical seal hardware which includes shaft sleeves gland rings collars compression rings and or pins.
