Key Features

• Zero Leakage to Atmosphere: The pressurized double seal arrangement uses a barrier fluid to ensure that any leakage is contained within the seal loop, never reaching the environment.

• Optimized for Hydrocarbons: FKM or FFKM O-rings are selected specifically for compatibility with crude oil, diesel, and refined petroleum products.

• Balanced Face Design: Hydraulically balanced faces reduce heat generation, crucial for preventing vaporization of volatile oils.

Q: Why use a double seal for oil?

A: Many oils are volatile, flammable, or hazardous. A single seal may leak small amounts of vapor. A double pressurized seal (Plan 53A) provides a buffer of clean fluid at a higher pressure than the product, ensuring zero process fluid escapes to the atmosphere.
