Find replacements for a wide range of pump shaft seals including a variety of crane us seal and sealol type seals.
What is a ceramic seal for a pump.
This subjects the pump seals to shots of up to 100 ethylene or propylene glycol which is well beyond the maximum recommended amounts for even silicon carbide seals.
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.
Our experience is that the standard carbon ceramic seal work fine with properly mixed glycol products designed for our industry.
This article will explain what a mechanical seal is and the key design features that make them work.
The majority of seals used in pumps are typically carbon ceramic.
Ceramic generally a 99 5 aluminum oxide offering excellent wear characteristics due to it s hardness.
The more common end or rotating face mechanical seal designs feature mating faces as the primary sealing elements.
Ceramic cannot however handle the thermal shocks that ni resist or 17 4 seats can.
It is chemically inert and can be applied to nearly any product.
