PCD is a continuous volumetric dispense pump based on the Progressive Cavity principle. PCD technology is an innovation in dispensing for a wide range of fluids, from low viscosity coatings to high viscosity greases. The many advantages of PCD technology will simplify your dispense process and improve reliability and quality in the long run. PCD Technology revolutionizes how you dispense and how you perceive dispensing. PCD is a continuous volumetric dispense pump based on the Progressive Cavity principle. PCD technology is an innovation in dispensing for a wide range of fluids, from low viscosity coatings to high viscosity greases.

The many advantages of PCD technology will simplify your dispense process and improve reliability and quality in the long run.The two primary parts of PCD continuously volumetric dispense technology are the rotor and stator. The rotor "threads" into the stator, and a "fluid engine" is generated between the two. The rotor is a stainless steel, double helix device with a complex geometry designed to push fluid through the single helix stator. In the fluid engine, two out-of-phase fluid chambers are deposited to the substrate.

When the rotor rotates, fluid is fed from chamber A, chamber A + B, or Chamber B. At any time in the dispense process the volume of fluid is the same.

  • Pump will not drip or drool
  • Dispense as much or as little as you need - volumetrically
  • Experience outstanding repeatability over the full range of fluid pot life
  • Level of fluid in a syringe will not affect the volumetric repeatability or capability of the pump
  • PCD dispense technology enhances dispense processes that require fluids ranging from very low viscosity, such as water, to thick pastes up to 80,000 cps

Suitable for:

  • Underfill
  • LED encapsulation
  • Flux or Grease
  • Conformal coatings
  • Silicones
  • And many more
