Volumetric Dispensing: Two-Part Mixing Pump

Precision 2K Dispensing with Disposable Static Mixing – No Recharge Required

The volumetric two-part (2K / bi-component) mixing pump utilizes advanced Progressive Cavity Displacement (PCD) technology to deliver highly accurate, repeatable dispensing of mixed materials. Engineered for performance and reliability, the system ensures precise volumetric flow of components A and B through a disposable static mixer, eliminating cross-contamination and simplifying maintenance.

Volumetric Two-Part Mixing Pump Key Features

  • True Volumetric Dispensing
    Precisely meters and delivers both components by volume for consistent mix ratios and repeatable results.
  • Valve-Free Mixing Head
    Reduces complexity and maintenance while eliminating potential leak paths.
  • Disposable Static Mixer
    Mixing occurs exclusively within the static mixer—the only wetted component—available in multiple sizes and lengths to suit various applications.
  • No Recharge Required
    Unlike piston-based systems, continuous operation is achieved without refill cycles, improving uptime and efficiency.
  • Reverse Flow (Suck-Back) Capability
    Prevents dripping and stringing for clean shut-off and improved process control.
  • Wide Viscosity Range
    Capable of processing low- to high-viscosity materials with consistent output.
  • Constant Volume Output
    Maintains accuracy even with temperature fluctuations or material batch variations.

Advanced Dispensing Technology

The system operates by transferring sealed, uniform cavities of fluid through a progressive displacement mechanism. This design enables:

  • High dispense rates
    With smooth, continuous flow
  • Gentle material handling
    Ideal for abrasive or filled materials
  • Extended component life
    As materials are pushed rather than sheared

The pump core consists of a Precision stainless steel rotor operating within a high-durometer elastomer stator, ensuring durability and consistent performance.
