DCCM-1100 - Double Concentric Cannister Mixers

The DCCM-1100 is a Double Concentric Cannister Mechanical Seal, externally mounted and designed specifically for mixers, agitators, and reactors operating in critical process environments.

Engineered for reliability and efficiency, this compact seal features monolithic, hydraulically balanced seal faces, ensuring superior performance under varying pressures and speeds.

Designed for API Plan 52, 53 and 54 systems, the DCCM-1100 delivers enhanced safety, extended seal life, and reliable performance, making it the ideal choice for high-performance mixing and reaction equipment.

Key Features:

  • Double Concentric Design – Provides optimal sealing for high-pressure applications and demanding process conditions.
  • Externally Mounted - The cannister design allows for the seal to be installed direct to an equipment plate without the need for a stuffing box/seal chamber.
  • Hydraulically Balanced Seal Faces – Minimizes wear and enhances seal longevity, reducing maintenance and downtime.
  • API Plan 53/54 Compatibility – Ideal for pressurized barrier fluid systems, ensuring zero process leakage and enhanced safety. Can also be used in unpressurised barrier Plan 52 systems
  • Stainless Steel Wetted Parts – Corrosion-resistant components for long-lasting durability in aggressive chemical and industrial applications.
  • Compact Cartridge Construction – The concentric mounted seal faces creates a compact double seal for equipment with limited physical space. The cartridge design provides easy installation and replacement, reducing assembly time and maintenance complexity.
  • Stationary Design – Self-aligning stationary seal faces, ideal for mixing equipment where the physical size of the equipment may create alignment issues
  • Integral Double Lip Seal - Prevents dust and debris collecting around outboard seal faces in top entry applications. Supplied with Drain connection orifice for leak face leakage detection.
  • Monolithic Seal Faces - Monolithic (one piece) seal faces are the face of choice for high temperature applications over shrink fitted seal faces with differential thermal expansions of the bi-materials.

Upgrade your mixers, agitators, and reactors with the DCCM-1100 – where precision engineering meets industrial strength.

Safe Operating Limits:

This seal incorporates best practice features and innovation as detailed in our technical blogs and white papers.

** Apply "industry standard" Pressure, Speed and Temperature de-rating factors, by shaft size and application. The safe seal performance characteristics are typical characteristics for each variable in isolation. The individual upper limit values of each variable should NOT be used in multiple combinations of Speed, Pressure and Temperature. Contact our Technical Sales Department for further details.
