Adhesives

Positive displacement pumps are ideally suited for transferring adhesives due to their ability to handle viscous, shear-sensitive, and sometimes abrasive materials with precision and care. Unlike centrifugal pumps, positive displacement pumps displace a specific volume of fluid with each cycle, ensuring a consistent flow rate that is crucial for maintaining the quality and integrity of adhesives during transfer. This is especially important when dealing with adhesives that require an even application to function correctly. Furthermore, these pumps offer superior control over pressure and flow, minimizing the risk of damaging the adhesive structure or altering its properties through excessive shear. Their versatility in handling a wide range of viscosities and their capability to pump fluids with uniform delivery make positive displacement pumps an excellent choice for adhesive applications.

Viking in the Process

Adhesives is a broad category covering many materials, presenting unique challenges for which Viking Pump has proven solutions. They may range in viscosity from water thin solvents to extremely viscous polymers. Some are shear sensitive and require larger pumps operating at slow speeds, and some require double seals with barrier fluid or magnetic drives to prevent air or humidity contact at seal faces which can cause sticking or crystallization. Viking’s O-Pro® seal provides a lower-cost solution with grease barrier between dual dynamic O-rings to prevent air infiltration at the seal.

Adhesive Applications

  • Manufacturing and packaging adhesives (e.g. PVAc, polyurethanes, epoxy resins)
  • Transfer from onsite blending (e.g. starch kitchen) to application and return
  • Metering onto items to be bonded

Universal Mag Drive, The Sealless Upgrade That Prevents Leakage and Fugitive Emissions
Viking Pump invented, patented and manufactured the very first sealless mag drive rotary positive displacement (PD) pumps in the world, and developed several series over time for different applications, including the first generation 825, 895 and 855 ™ internal gear pumps. Of these first generation mag drive pumps, all had different footprints from their dynamically-sealed cousins with...

Viscosity Through Thick and Thin
Viscosity is a measure of a liquid’s resistance to flow. And you don’t need to work in a laboratory to observe this. Anyone who’s spent any time in the kitchen has observed a variety of liquids with a wide variety of viscosities.
