Single Heavy Duty Multi-Spring Slurry Cartridge Mechanical Seal

Mechanical Seal Style RKCS

Heavy Duty Interchangeable Slurry Seal

With four (4) configuration options all incorporating additional engineered features such as reverse pressure capability, non-clogging multi-springs, rugged seal drive operation, and hydraulically balanced faces, the RKCS single and RKCD dual seals successfully contend with the industry’s toughest slurry challenges.

100mm Slurry Seal
 

FEATURES:

RKCS Version A

​Integral Spring Shield is manufactured from a flexible and durable material to effectively shield the springs from debris and slurry during operation. Compatible with API 682 Plan 32. Flush connection optional.

 

RKCS Version B

(For grease-filled operation)

Addition of bolt-on lip seal assembly and two (2) additional O-rings. Compatible with API 682 Plan 32. Flush connection optional.

 

RKCS Version C

(Quench operation)

Fluid Guide Sleeve added to Version B to support the effective removal of debris during quench operation. Compatible with API 682 Plan 32. Flush connection optional.

 

RKCD (Dual Seal)

dual seal option designed for the most rigorous slurry processes. In addition to Version C’s Fluid Guide Sleeve, this option is engineered for optimum service when paired with either an API 682 Plan 53A buffer or API 682 Plan 54 barrier fluid seal support system.
