Polyurethanes
Gear pumps are the best solution for transferring polyurethane liquid due to their precision, reliability, and ability to handle viscous substances without compromising efficiency. Polyurethane, being a material that requires careful handling to maintain its properties, benefits from the continuous, non-pulsating flow provided by gear pumps. This mechanism not only minimizes shear, which can degrade the material, but also provides exceptional control over flow rates, crucial for applications requiring precise dosages.

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.
