Hot Melt

Positive displacement pumps are ideal for manufacturing hot melt due to their ability to handle highly viscous materials and maintain a consistent flow rate, which is essential in the production processes that require precise application and distribution. Unlike centrifugal pumps, positive displacement pumps are not affected by changes in viscosity, ensuring that hot melt adhesives and materials are delivered accurately and with minimal pulsation. This precision helps in maintaining the quality and performance of hot melt products, reducing waste and inefficiencies. Additionally, these pumps are robust and can effectively manage the high pressures and temperatures often associated with hot melt manufacturing, making them a reliable choice for industries focused on producing high-quality adhesive solutions.

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.

Current and Flow: An electrical engineer’s guide to the concepts of fluid systems
Unlike most of my colleagues I didn’t start out with a mechanical background.  While they were studying kinetics and machine design, I was studying digital electronics and industrial power.  When I started my career in the world of pumps, I had to learn a whole new set of concepts.  What was surprising was that while the terminology may be a bit different, the concepts are very similar.  Think of the following as a “Rosetta Stone” for translating the common terms and concepts of fluid systems to your more familiar terms and concepts of electrical systems.
