Water Pump Mechanical Seal Material

The more common end or rotating face mechanical seal designs feature mating faces as the primary sealing elements.

Water pump mechanical seal material.

These seals require lighter packing pressure than standard oil and water resistant packing seals so they cause less friction and reduce shaft wear. 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. They re made of graphite impregnated aramid fiber and are for use in pumps and valves. 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.

Other mechanical seal hardware which includes shaft sleeves gland rings collars compression rings and or pins. Highly cost effective and reliable for high volume water systems swimming pools shower pumps central heating irrigation. Vulcan seals water pump mechanical seals. The load the seal faces receive are engineered into the design of the seal.

The faces in a typical mechanical seal are lubricated with a boundary layer of gas or liquid between the faces. We recommend the epr sic sic material since that seal can handle ph up to 12 5 which gives some wiggle room.
