Peristaltic pump

A peristaltic pump is a special type of positive displacement pump that transports liquids by compressing and expanding a flexible tube. This type of pump is primarily used where precise conveying and gentle handling of media that can be sensitive to mechanical influences are required.

The peristaltic pump operates according to the principle of peristaltic conveying. The tube is compressed by a rotating roller or cylinder unit, pushing the liquid through the tube, similar to the movement of food pulp in a digestive tract. As soon as the roller releases the tube, the tube retracts, creating a vacuum that draws the liquid along.

Gentle conveying: Since the liquid does not come into contact with moving parts, it is not subjected to mechanical stress, making it ideal for sensitive media such as food, pharmaceuticals, or biological fluids.

Accuracy and dosing: Peristaltic pumps are capable of conveying precise quantities, making them suitable for applications in the chemical industry or in dosing systems.

Dense liquids and sludge: Peristaltic pumps can also transport viscous or thick media without clogging.

Easy maintenance: The hose can be easily replaced without disassembling the entire pump.

No leaks: Due to their design, no leaks occur, as the pumping process is completely hermetic.
