Kalvopumpuissa

Kalvopumpuissa is a term of Finnish origin referring to diaphragm pumps. These pumps are a type of positive displacement pump that utilize a flexible diaphragm to move fluid. The diaphragm is moved back and forth by a mechanical linkage, creating a pumping action. When the diaphragm moves away from the pumping chamber, it creates a vacuum, drawing fluid into the chamber through an inlet valve. As the diaphragm moves back towards the chamber, it expels the fluid through an outlet valve. This mechanism allows for a consistent flow rate and can handle a variety of fluids, including those with solids or abrasive particles.

Diaphragm pumps are known for their ability to operate dry without damage and their leak-proof design, making them suitable for hazardous or sensitive materials. They are often used in chemical processing, water treatment, and in applications where precise dosing is required. The materials used for the diaphragm and pump body can be selected to be compatible with the fluid being pumped, offering good chemical resistance. Maintenance typically involves replacing worn diaphragms and valves. Their operational principle makes them a versatile choice for many industrial and laboratory applications.
