Cartridge Mechanical Seals

AS&P, AST, Delta, Flow Serve, Latty, Utex, Vulcan.  Each of these companies provides quality seals. Where we have value is in providing the technical support and recommendation of what brands product is best for your requirements.

The process usually begins when the customer tells us what they want.  Often the brand, the materials of construction, and the style is already known.  If you want a John Crane metal bellows seal, we will supply it.

Other times the application is known, but the seal is still inside the pump and the records of what was put into the pump last don’t exist.  That is where we can help.  Armed with the application parameters, and the style of pump we may have the solution.

Some customers just send us the seal from the pump.  Not only do we repair seals, we can also replicate hard to find seals.  When we identify your seal, we have the capability to improve its performance.  By replacing Carbon, Ceramic, 17-4, or Niresist with  Silicon Carbide or Tungsten Carbide your seals can run 5 to 10 times longer.  Ordering the upgraded repairable seal, and a replica of the improved version of that seal gives you 2 seals for the price or one and a half.

AST 7023 – Hot liquid Seal

• API Plan 23 (ANSI Plan 7323) is the most reliable and economical way to cool a seal.  The sealed liquid is circulated from the seal chamber (not the pump discharge) through a cooler and back to the seal. Since only the liquid around the seal is cooled, the heat load on the cooler is minimized and process energy is conserved.
