The most common question we get is what should i use, Pump Packing or a Mechanical Seal?

Packing is excellent in a wide range of applications. The factors to consider are is leakage acceptable, and what cost target are you trying to stay under in the short term and long term. Mechanical seals are generally more expensive initially. However the longer you keep your pump in service, the more cost effective a mechanical seal can be. Most packings must leak an average of 6 drops per minute (with the exception of flexible graphite), to lubricate the shaft. American Seal & Packing stocks both packing and mechanical seals, and can help you decide what is best in your application.
