Key Features

• Hydraulically Balanced: The stepped shaft/sleeve design of this balanced mechanical seal reduces the closing force on the seal faces, allowing operation at higher pressures (up to 50 bar) common in hydrocarbon pumping, a critical feature for ensuring the reliability of the O ring mechanical seal in such demanding conditions.

• API 682 Type A Equivalent: This balanced mechanical seal is designed to meet the requirements of API 682 Type A pusher seals, making it an ideal and reliable O ring mechanical seal for refinery and other high-pressure hydrocarbon services.

• Low Heat Generation: The balanced geometry of this balanced mechanical seal minimizes friction, preventing the vaporization (flashing) of volatile hydrocarbons like propane or butane, thereby protecting the integrity and function of the O ring mechanical seal.

• Anti-Extrusion Rings: O-rings are equipped with backup rings to prevent extrusion under high pressure.

• Robust Drive Keys: This balanced mechanical seal utilizes milled drive slots and keys to handle high torque start-ups without transferring stress to the bellows or spring, ensuring the mechanical stability and longevity of the entire assembly, including the critical O ring mechanical seal elements.

FAQs about O-Ring Balanced Mechanical Seal for Hydrocarbon Pump

Q: What is a "balanced" mechanical seal?

A: A balanced mechanical seal has a design where the area of the seal face exposed to hydraulic pressure is reduced. This means less force pushing the faces together, allowing the seal to run cooler and last longer at high pressures compared to unbalanced seals.
