Mechanical seals require clean water or other compatible liquid for the lubrication of the seal faces.
Water pump mechanical seal material.
The other key aspect of a mechanical pump seal is how to maintain the seal.
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.
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.
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.
Highly cost effective and reliable for high volume water systems swimming pools shower pumps central heating irrigation.
These seals require lighter packing pressure than standard oil and water resistant packing seals so they cause less friction and reduce shaft wear.
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.
