With the new, third generation cartridge seals, we have the ability to meet customers’ increasingly stringent emission control needs with greatly extended MTBPM (Mean Time Between Planned Maintenance).

442 Split Seal

We can now reference emissions in just a few parts per million – well within regulatory compliance limits.  Our total line of general service and specialized mechanical seals can fulfill the plant-wide needs of most process industries and a surprisingly cost-effective value.  Now, with the new Streamline™ S10 Single and S20 Dual Seals we can offer plant-wide fluid sealing needs in one set of seals.  But the S-Series goes beyond the basics of fluid sealing, to address the economies of total sealing workflow. S-Series will streamline inventory, simplify seal selection, reduce installation complexity and minimize total maintenance costs.

Chesterton’s Engineered Solutions cell can also provide out-of-the-box thinking for difficult to seal and custom applications.
