Ravtech Low-Drag Extreme Performance (LDEP) Seal Features:

Aerospace Quality

·All Ravtech LDEP seals are produced in accredited

aerospace manufacturing facilities.

Sustained High Temperature

& High Rubbing Speed Capability

·Long-Life

·Unequaled reliability

Lower Coefficient of Friction

Dynamic frictional coefficients of 0.05 to 0.1 are typical for

Ravtech LDEP seals.

Reduced Face Loading

Ravtech LDEP seal face loads are unaffected by shaft

position

·Less heat generation

·Longer wear

·Less power loss from friction

Greater Tolerance For High

Surface Speeds

Ravtech LDEP seals can tolerate rubbing speeds of up to

21,000 feet per minute

·No spring bounce

·No chatter

·No spring fatigue

Springs Trap Fluids

·Oil & other organic fluids can "coke" at high temperatures, impeding lubrication.

·Ravtech LDEP seals constantly circulate oil as they rotate allowing them to run cool.

High Temperature Capability

·Ravtech LDEP seals can be designed to withstand temperatures up to 600° F (316° C)

Magnetically Controlled

Sealing Surfaces

·Seal faces are lapped to within two helium light bands.

·Seal faces mate and seal on installation.
