Peristaltic Pump Types: Dispensing Peristaltic Pump, Peristaltic Pump Flow Rate, Variable Speed Peristaltic Pump

Peristaltic pumps are widely used in various industries for dispensing fluids and controlling flow rates. These pumps operate based on the principle of peristalsis, where a flexible tube is squeezed by rotating rollers or shoes to create a pumping action.

The working principle of dispensing peristaltic pump

The working principle of the dispensing peristaltic pump is to use the peristaltic pump to transport the glue to the glue needle, and to achieve high-precision liquid dispensing by controlling its speed and dispensing time. Specifically, peristaltic pumps push liquid flow through constant deformation and recovery, and their core component is the “peristaltic tube,” which is a pipe that can be deformed. When the “roller” inside the peristaltic pump rotates, it constantly squeezes and relaxes the peristaltic tube, thus pushing the liquid flow. The output flow rate and speed of the peristaltic pump can be controlled by adjusting the speed of the roller and the diameter and length of the peristaltic tube.

Advantages of dispensing peristaltic pump

Dispensing peristaltic pumps are specifically designed for accurate and precise fluid dispensing applications.They offer several advantages such as high repeatability, minimal maintenance requirements, and compatibility with a wide range of fluids.The pump’s design ensures that there is no direct contact between the fluid being dispensed and any moving parts, eliminating the risk of contamination.

Dispensing peristaltic pump application

When it comes to peristaltic pump flow rate, it can be adjusted by varying parameters such as tubing size, rotational speed, and compression force applied to the tubing. A dispensing peristaltic pump is a type of pump that uses rotating rollers to compress and decompress a flexible tube, creating a pumping action. It is commonly used in various industries for precise liquid dispensing applications. The advantage of using a peristaltic pump for dispensing is its ability to provide accurate and repeatable flow rates.

Introduction of peristaltic pump flow rate

Peristaltic pumps are known for their ability to control the flow rate of liquids. The flow rate refers to the volume of liquid passing through the pump per unit time. In the case of a peristaltic pump, the flow rate can be adjusted by changing the rotational speed or adjusting the compression force applied by the rollers on the tube. This flexibility allows users to achieve different flow rates according to their specific needs.

Introduction of variable speed peristaltic pump

Variable speed peristaltic pumps offer an additional level of control over the pumping process. By adjusting the rotational speed, users can precisely regulate both low and high-flow rates as required by their application. This feature makes variable speed peristaltic pumps suitable for tasks that demand varying fluid volumes or require gradual changes in flow rates.

Function and principle of variable speed peristaltic pump

Variable speed peristaltic pump is mainly used in scientific experiments and industrial production, its role is to transport the fluid according to a certain flow and pressure to the place where it is needed, common application fields include medicine, chemical, environmental protection, food and pharmaceutical.

The variable speed peristaltic pump works by converting rotary motion to reciprocating motion by squeezing the hose through multiple sliders on the spoke to push the fluid out. In normal operation, the extrusion of each slider is the same, so as to ensure a stable flow and pressure output, while the transmission can adjust the output of the pump according to the fluid demand.

Advantages of variable speed peristaltic pump

Variable speed peristaltic pumps take flow rate control one step further by allowing users to adjust the rotational speed of the pump motor. This feature enables fine-tuning of flow rates within a wider range while maintaining accuracy and consistency. Variable speed capability enhances process optimization possibilities in industries like pharmaceuticals, food processing, laboratory research, etc., where different viscosities or volumes need to be accommodated.


In conclusion, these three products dispensing peristaltic pump, peristaltic pump flow rate, and variable speed peristaltic pump – all relate to different aspects of utilizing this type of technology in fluid handling applications. Whether it’s achieving accurate dispenses, controlling desired flow rates or having adjustable speeds for versatile operations, these features make them valuable tools across various industries.
