SOLVE YOUR TOUGHEST SEALING CHALLENGE WITH THE MOST VERSATILE SLURRY PUMP SEAL IN THE INDUSTRY

In the demanding world of slurry pumping, where abrasive materials and challenging conditions are the norm, reliability and efficiency are non-negotiable. The Rock Killer Crusher (RKC) Series sets a new standard for heavy-duty flushless slurry pump seals, designed to conquer the harshest applications in industries such as mining, mineral processing, and flue gas desulfurization.


The RKC Series Advantage: 

Engineered with ease of maintenance and operational efficiency in mind, the RKC Series stands out as a single cartridge slurry seal that operates seamlessly with zero external flushing. Offering four (4) configuration options, the RKC Series incorporates advanced features like reverse pressure capability, non-clogging multi-springs, rugged seal drive operation, and hydraulically balanced faces. These features collectively make the RKC Series seals a reliable solution for the toughest slurry challenges in various industries.


Design Features and Benefits: 

Let's delve into the key design features and benefits that make the RKC Series a game-changer in the slurry pump seal market:


Ease of Fitment and Maintenance:
  • Designed as a simple maintenance cartridge with compatibility for popular slurry pump conversion kits, ensuring easy fitment and simplified maintenance procedures.

Durability in Service:
  • Constructed with abrasion and corrosion-resistant materials to promote longevity in service, making the RKC Series seals ideal for prolonged use in challenging environments.

Flushless Sealing Capability:
  • Unique seal design, coupled with pump features, allows for single-face flushless sealing of slurries containing up to 60% solids by weight, showcasing versatility in handling varying slurry compositions.

Optimized Face Design:
  • Stationary face multi-spring design with isolated springs, ensuring durability and reliability by keeping springs away from the pumped media.

Efficient Heat Dissipation:
  • Large and open inner seal chamber that self-evacuates, preventing the packing in of materials and effectively dissipating heat during operation.

Adaptability for Special Circumstances:
  • For special circumstances, an outboard lip seal is installed, and Plan 62 grease or water quench is provided to lubricate the seal faces during dry-running pump cycles.


Applications: 

The RKC Series excels in sealing applications across various industries, including but not limited to:

  • Alumina Refining

  • Gold Mining

  • Hard Rock Mining

  • Coal Prep/Washing

  • Flue Gas Desulfurization (FGD)

  • Ore Mining

  • Synthetic Rutile Plant

  • Pigment Plant

  • Industrial Processes

  • Aggregates
