Pumpesprøytesystemer

Pumpesprøytesystemer, also known as plunger pump systems, are mechanical devices used to deliver a precise and controlled volume of liquid. They typically consist of a cylinder, a piston (plunger), an inlet valve, and an outlet valve. The plunger moves within the cylinder, creating a vacuum that draws liquid in through the inlet valve. As the plunger moves in the opposite direction, it forces the liquid out through the outlet valve under pressure. The volume of liquid dispensed is determined by the stroke length of the plunger and the internal diameter of the cylinder.

These systems are valued for their accuracy and repeatability, making them suitable for applications requiring precise fluid handling. They are often used in laboratories for dispensing reagents, in medical devices for administering medication, and in industrial processes for precise chemical dosing. The materials used in their construction can vary depending on the type of liquid being handled, with common options including glass, stainless steel, and various plastics and elastomers to ensure compatibility and prevent contamination. Maintenance usually involves cleaning and occasional replacement of seals or valves to maintain optimal performance.
