ROCK KILLER CRUSHER (RKC) SERIES: HEAVY-DUTY FLUSHLESS SLURRY PUMP SEAL SOLUTIONS

In high-demand applications like mining, mineral processing, and flue gas desulfurization, slurry pumps operate under extreme conditions. Reliability and efficiency are critical—especially when dealing with abrasive slurries. That’s where the Flexaseal Rock Killer Crusher (RKC) Series stands out. Designed for the harshest slurry applications, the RKC Series offers flushless mechanical seal technology built to last.

Why Choose the RKC Series Slurry Pump Seal?

The Flexaseal RKC Series slurry pump seal is a single cartridge mechanical seal designed for ease of maintenance and maximum operational uptime—without the need for external flushing. Available in four configurations, it’s engineered with advanced features such as:

• Reverse pressure capability

• Non-clogging multi-springs

• Rugged seal drive operation

• Hydraulically balanced faces

These design elements deliver dependable performance across a variety of abrasive and corrosive environments.

Key Design Features and Benefits

1. Easy Installation and Maintenance

• Designed as a plug-and-play cartridge seal.

• Compatible with popular slurry pump conversion kits.

• Simplifies routine maintenance procedures.

  
  

2. Durable in Harsh Conditions

• Built from abrasion- and corrosion-resistant materials.

• Ideal for long-term service in demanding applications.

  
  

3. Flushless Operation

• Seals slurries with up to 60% solids by weight without external flush systems.

• Reduces water usage and maintenance requirements

  
  

4. Multi-Spring Face Design

• Stationary face and isolated springs keep components clear of pumped media.

• Increases seal reliability and extends service life.

  
  

5. Self-Evacuating Seal Chamber

• Open internal geometry prevents material build-up.

• Efficiently dissipates heat to protect internal components.

  
  

6. Adaptability for Dry-Running Cycles

• Optional outboard lip seal with Plan 62 grease or water quench system.

• Maintains seal lubrication even during temporary dry running.

  
  

Ideal Applications

The RKC Series is suited for a wide range of slurry handling processes, including:

• Alumina refining

• Gold and hard rock mining

• Coal preparation and washing

• Flue gas desulfurization (FGD)

• Ore and mineral processing

• Synthetic rutile and pigment plants

• Industrial wastewater

• Aggregate processing

Configuration Options

The RKC Series offers four distinct configuration options to cater to different operational needs:

RKCS Version A

1. 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

2. 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

3. 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.

RKCS Version D

4. RKCD (Dual Seal)

A 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.

Each configuration is tailored to meet specific challenges and industry requirements, ensuring versatility and reliability in a range of applications.

In conclusion, the Flexaseal Rock Killer Crusher (RKC) Series stands as a testament to innovation in mechanical seal technology, offering reliability, efficiency, and savings for the slurry pump seal market. Whether you're dealing with abrasive mining slurries or challenging industrial processes, the RKC Series is engineered to deliver optimal performance, making it a standout choice in the world of heavy-duty flushless slurry pump seals.
