Eliminates the need for lubrication and coupling maintenance
Coupling can be inspected without disassembly
Condition of disc packs can be inspected with a strobe light while the machine is running
(Note: It is not recommended that couplings be operated without coupling guards. )
Easy to assess equipment misalignment
Torsionally rigid without any backlash
No wearing parts
Resistance to harsh environments
Long life when properly sized and aligned
High power density (higher torque for a given outside diameter)
EP supports the API-610 Standard up to 3, 800 RPM
Unitized disc packs assure repeatability essential for meeting the total amount and piloting requirements since mandated by API-610

Disc Couplings
EP takes great pride in being able to offer a wide variety of superior disc coupling products in models designed to meet the application needs of today’s worldwide power transmission market.
Using advanced design techniques, implementation of Finite Element Analysis, and extensive testing of materials, EP has developed an innovative disc pack profile design revolutionary to traditional disc pack designs found in the market. This disc pack can accommodate 1/2° to 1-1/2° of angular misalignment, and is used in all EP disc coupling products.
EP disc packs are manufactured using high grade stainless steel (AISI-301), ensuring high strength, high endurance to fatigue, and resistance to most environmental conditions.
EP disc couplings utilize unitized disc packs with 4, 6 or 8 bolt designs. As the 8 bolt style can transmit better torque compared to the 6 or 4 bolt style, it is not in a position to accommodate as very much angular misalignment.
EP couplings may also be fitted with overload bushings to safeguard the disk pack during momentary torsional overloads.
