Mechanical Seals

A failed seal means your pump is offline and your team is under pressure. You need the correct replacement identified, confirmed compatible, and shipped fast. As a mechanical seal distributor in Texas, Tejas Pump & Equipment supplies component seals, cartridge seals, and OEM-compatible replacements for pumps and motors across Oil & Gas, Chemical & Petrochemical, Food & Beverage, and heavy industrial operations. Every seal we provide is sourced through authorized OEM channels with full factory warranty and documentation.

John Crane Seal Replacements

John Crane is one of the most widely installed mechanical seal brands in industrial service. When a John Crane seal fails, you need an exact match on dimensions, materials, and performance specs to get your pump back online without modification.

What We Supply:

  • Direct OEM John Crane seal replacements with factory certification
  • OEM-compatible alternatives that meet the same dimensional, material, and performance specifications as the original
  • Replacements for legacy and superseded John Crane models, with cross-reference verification before shipment

How We Ensure the Right Fit:

Our team cross-references your existing seal model number, pump make and model, shaft size, and seal chamber dimensions before anything ships. If the original model has been discontinued or superseded, we identify the current replacement and confirm compatibility with your specific equipment. Send us your seal model number or pump nameplate data and we will handle the rest. Request your John Crane replacement.

Pump Shaft Seals for API & ANSI Pumps

Seal requirements differ significantly between API 610 and ANSI B73.1 pump standards. We supply pump shaft seals for API & ANSI pumps with the specifications matched to each standard’s requirements.

API 610 Pump Seals:

  • Seals specified to API 682 standards for qualification, testing, and documentation
  • Configurations for all API Plan arrangements, including Plan 11, 13, 23, 32, 53A/B/C, and 54
  • Seal chamber bore and depth matched to your pump’s type designation (OH, BB, or VS)
  • Face materials, including carbon, silicon carbide, tungsten carbide, and specialty materials rated for your process fluid and operating temperature

 

ANSI B73.1 Pump Seals:

  • Component and cartridge seals sized to standardized ANSI seal chamber dimensions
  • Material combinations matched to your specific chemical exposure, including elastomers rated for the fluid and temperature in your process
  • Drop-in replacement compatibility that eliminates modification to the pump or gland


Proper seal selection for either standard depends on your actual operating conditions, not just the pump nameplate. Our team reviews your process data to confirm the correct seal type, face combination, and elastomer selection. Contact us with your pump specs.

Cartridge Seals for Oilfield Equipment and Process Service

Cartridge seals ship as a pre-assembled, pre-set unit with the seal, gland, and sleeve ready for installation. Your technicians install them without measuring, setting heights, or adjusting spring compression in the field, which eliminates the installation errors that are the leading cause of early seal failure.

Available Configurations:

  • Single seals for standard process service
  • Dual pressurized and dual unpressurized arrangements for hazardous, toxic, or high-value fluids requiring secondary containment
  • Split cartridge seals for large-bore equipment and applications where the pump cannot be fully disassembled

 

Built for Demanding Conditions:

  • Abrasive produced water and sand-laden fluids in upstream oil and gas production
  • High-pressure injection and chemical transfer service
  • Corrosive environments with H₂S and CO₂ exposure
  • Sanitary and hygienic applications in food and beverage processing

Cartridge seals for oilfield equipment and process applications reduce your maintenance team’s installation time and increase first-run reliability  Request a quote for your cartridge seal specification.
