ASP-2 Mechanical Seal

Pumps require quality shaft seals. The more severe the service, the more durable the seal must be. Using quality hard seal faces is generally less expensive in the long run.


Seal Products

Not all pumps have the space required to accommodate a type 1E or 21C. The Type 2D was designed for short stuffing boxes by shortening the spring and widening the spring. The wider spring allows us to drop the seal head to the inside dimensions of the seal spring. As long as your stuffing box is wide enough to accommodate the seal (most are), The Type 2D can be used in deep stuffing boxes with the use of a lock collar.

Mechanical Seals

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.
