Lösungspumpe

A Lösungspumpe, often translated as a solvent pump or displacement pump, is a type of pump used in laboratories and industrial processes to transfer solvents. Unlike other pump types that may rely on centrifugal force or positive displacement of a fluid volume, a Lösungspumpe typically operates by creating a vacuum or pressure differential. This differential draws the solvent from one container and pushes it into another. They are particularly useful for safely and efficiently dispensing or moving volatile or corrosive solvents where direct pouring or exposure might be hazardous or lead to evaporation.

These pumps are often designed with materials resistant to a wide range of chemicals, ensuring compatibility with various solvents. Common mechanisms include diaphragm pumps, peristaltic pumps, or simple piston-driven systems, all engineered to handle liquid transfer without introducing contaminants or excessive shear. The precise operation of a Lösungspumpe allows for controlled flow rates, which is essential in applications like chromatography, titrations, or chemical synthesis where accurate reagent delivery is critical. Their robust construction and chemical inertness make them a staple in analytical, research, and manufacturing environments.
