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.
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.
Vulcan seals water pump mechanical seals.
The load the seal faces receive are engineered into the design of the seal.
Mechanical seals require clean water or other compatible liquid for the lubrication of the seal faces.
These seals require lighter packing pressure than standard oil and water resistant packing seals so they cause less friction and reduce shaft wear.
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.
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.
The other key aspect of a mechanical pump seal is how to maintain the seal.
