Description

The 711909 O-RING FKM is a high-quality sealing component manufactured by Blackmer and supplied exclusively by KI Pumps, based in Waukesha, WI. This O-ring is designed to fit a variety of pump applications, particularly in positive displacement and sliding vane pumps. It features a composition of fluoroelastomer (FKM), commonly known as Viton, which provides excellent chemical resistance, high-temperature tolerance, and durability suited for demanding industrial environments.

Constructed from high-grade FKM material, the 711909 O-RING offers a precise 2-246 inch (approximately 2.25 inches) inner diameter size, ensuring compatibility with specific pump model fittings. Its cross-sectional thickness measures 1/8 inch (3.18 mm), providing a strong, reliable seal under pressure. The O-ring’s diameter and material composition contribute to resistance against oils, fuels, acids, and other aggressive chemicals, making it suitable for various industrial, petrochemical, and hydraulic applications.

Key features include:

  • Inner diameter: approximately 2.246 inches
  • Cross-sectional thickness: 1/8 inch
  • Material: fluoroelastomer (FKM/Viton)
  • Temperature resistance: -20°C to +200°C
  • Chemical resistance: oils, fuels, acids, and solvents
  • Designed for sealing in pumps, valves, and hydraulic systems

This 711909 O-RING is ideal for use in industrial pump repair, fluid handling systems, and applications requiring reliable sealing under high-pressure conditions. It is especially suitable for maintenance and replacement in Blackmer pumps, ensuring performance and longevity without significant budget expenditure.

The O-ring is supplied as a single unit, and no additional accessories are included. Proper installation requires clean, free surfaces to ensure optimal sealing performance. It is recommended to inspect the O-ring regularly for signs of wear or damage and replace it as needed to maintain system integrity. Cleaning involves using compatible solvents; avoid abrasive tools that could damage the FKM material. The O-ring has an expected lifespan of several years with proper maintenance, based on operating conditions.
