Pump engineers have a wide range of sealing options available to them which cater for the diversity of pump applications. In designing pumps and other associated equipment like compressors and valves which need maximum efficiency and long-lasting performance, the flexibility of elastomers sets them apart from other pump sealing materials available. It is the ability of an elastomer to return to its original, undeformed shape after the removal of force (unlike rigid sealing materials like PTFE) that provides sealing performance helping the pump designer to prevent leakage under the most demanding pressures and operating environments…
