The Future of Precision Dispensing: Progressive Cavity Pump

Progressive Cavity Pumps (PCPs) have been driving impacts in many dispensing processes due to their exceptional capabilities and versatility. These innovative dispensing pumps offer numerous advantages that cater to a wide range of industries and applications, from precision dispensing for semiconductor’s applications to handling abrasive fluids in other manufacturing processes. In this article, we will explore the unique features of PCPs and how they are transforming the way we dispense adhesives in various sectors.

The Smooth Flow: Pulsation-Free Dosing

One of the standout features of PCPs is their ability to provide pulsation-free dosing. By combining the precise control of the pump by time and rotor speed with the eccentric screw pump principle, PCP offers one of the best dispensing results.  Unlike traditional dosing methods that often do not offer volumetric dispensed volume, PCPs ensure a smooth and consistent fluid delivery. This feature is especially important for line dispensing applications with precision and consistency requirements. 

Viscosity Knows No Bounds

PCPs are not easily daunted by high viscosities. In fact, they can handle fluids with viscosities reaching up to a staggering 7 million centipoises (cps). This remarkable viscosity tolerance enable PCP to be highly effective in dispensing Silicone RTVs, TIM and solder paste in various industries.

Gentle Handling: Low Shearing Stress

In industries where shear-sensitive substances are involved, PCPs shine. They exert very low shearing stress on the fluids they handle, ensuring that delicate materials retain their integrity throughout the dosing process. This quality is a game-changer for industries that dealing with shear-sensitive products.

Versatility Beyond Compare

PCPs are known for their versatility. They can handle abrasive fluids with high content of solid particles making them indispensable in manufacturing processes involving cutting-edge materials and challenging environments. On the other extreme end, they can dispense solvent and medical fluid with high volumetric tolerances.  Thus they can handle applications from medical to consumer electronics and 3D printing.

User-Friendly Operation

Ease of operation is a key feature of PCPs.  Volumetric quantity to be dispensed can be achieved simply by setting speed and time.  In some systems, you can even set the volume that you wanted. 

Drip Prevention and Efficient Container Emptying

PCPs come equipped with an adjustable reverse-flow feature that prevents dripping. This ensures that no material is wasted during the dispensing process, ensure volumetric dispensed volume and prevent accidental dripping of materials onto other areas.

Additionally, their capability for almost complete container and barrel emptying minimizes material waste, making them eco-friendly options for environmentally conscious industries.

Embracing Automation

Automation is on the rise across industries, and PCPs seamlessly integrate into our automated fluid dispensing systems. Their user-friendly design allows for easy integration into robot cells, making them an ideal choice for tasks requiring precision and consistency. Industries such as electronics, semi-conductors and medical equipment manufacturing are benefiting from this feature by achieving higher production efficiency.

Advanced Design Elements

The design of PCPs includes advanced features like the DLC Coated Rotor, which offers remarkable durability compared to traditional Chrome Plated Rotors. The DLC Coated Rotor lasts approximately 4-5 times longer and extends the stator’s lifespan by 2-3 times when used in combination. This is particularly valuable in applications where long-term durability is a priority.

Material Compatibility

PCPs are compatible with a wide range of materials, from adhesives (including 1- and 2-component, UV curing, and moisture curing) to epoxy resins, acrylates, silicones, polyurethanes, potting and sealing compounds, solder paste, thermal pastes, gap fillers, grease, food ingredients, and pharmaceutical liquids. This compatibility is a testament to their adaptability across industries and applications.
