Series 3000

The FSI 3000 Series mechanical seal is a multiple spring design available in both balanced and unbalanced configurations. The basic 3B/3B-1 can be offered for single, dual, or tandem operation. Most 3000 Series mechanical seals are custom engineered designs due to operating conditions and / or equipment type.

FEATURES:

  • Normally cartridge seal mounted for ease of installation and equipment accommodation

  • Can be used as either a rotating spring design or as a flexible stator design depending on operating parameters

  • Required seal face designs and balance ratios can be calculated to ensure optimum performance

  • Can be furnished with pumping ring or circulating shroud for API Plan 23 or 53 operation

TYPICAL APPLICATIONS WOULD INCLUDE:

  • Refinery & Petrochemical light hydrocarbon services

  • High pressure multistage pumps

  • Circ water & cooling water services

  • Boiler Feed pump applications

  • Specialty Equipment applications

SERIES 3000 ACCESSORIES:

  • Close clearance restriction bushings, floating throat bushings, and lip seals for use in conjunction with API Plans 21, 23, and 32.

  • A complete line of standard and custom designed seal reservoirs to support tandem and double seal operations per API Plans 52 and 53.

  • Specifically sized and selected heat ex-changers for proper seal cooling when using API Plans 21 and 23.

  • Custom engineered bearing isolating devices for specialty equipment applications.
