682C Series Seals

PPC’s 682C Series of cartridge seals are a complete line of high temperature seals meeting the criteria of the Type C design under API Standard 682, completely manufactured by us at our corporate facility in Baton Rouge, LA. These designs are balanced, internally mounted cartridge non-pusher seals with a flexible metal bellows element and static graphite secondary sealing members. Designed as Category 2 seals per API 682, these designs are fully compatible with API 610 pumps.

Per the latest API 682 publication, the standard seal design features a stationary flexible element (metal bellows) for Arrangement 1 (single) seals. Under the API Standard, the seals are applicable to process temperatures up to 750 °F (400 °C), although engineered designs may be suitable for even greater temperatures.

682C Series seals may be provided in all three API Arrangements (single, tandem, double), and may be configured to suit individual applications.
