Hard-wearing seal material for pump applications

The company said the material will enable process engineers and managers in the chemical, petrochemical, oil and gas, and water industries to benefit from increased pump reliability, reducing downtime and operational costs.

Mechanical seals are an essential part of pumps, sealing the rotating shaft of the motor from the pumping fluid.

They trap a thin film of liquid, which acts as a lubricant as well as a seal.

Occasionally, pumps continue to run when there is no fluid present; during this time, the seals experience increased friction and high temperatures.

As a result, the O-rings can degrade and when the fluid starts circulating, the seals leak.

Morgan Technical Ceramics said that its silicon carbide offers good resistance to abrasion, low thermal expansion coefficient and excellent thermal shock resistance.

The company added that the material exhibits superior mechanical properties and extreme hardness and wear resistance, providing good sealing performance for heavy duty applications.

It continues to give high performance when pumping contaminated, abrasive and corrosive fluids and provides effective sealing of fluids under high pressure.
