Metering pumps and peristaltic pumps are common industrial pump categories and are widely used in different fields. Their working principle and application environment are slightly different, and this paper will make a detailed comparison from multiple dimensions to show the characteristics and applicability of the two for readers. Whether you are a practitioner in the relevant industry or a reader interested in this field, this article will provide you with useful information.
First, let's look at metering pumps. Metering pump is a kind of equipment to achieve accurate metering through displacement adjustment. Its working principle is driven by a motor to make the plunger or pulse motor reciprocate, so as to work the flow of liquid in the room. Metering pumps are commonly used in scenarios that require accurate metering, such as the chemical, pharmaceutical and food industries. Due to its high precision, stable and reliable characteristics, metering pumps are widely used in the process of controlling flow.
In contrast, the working principle of the peristaltic pump is more special. Peristaltic pumps deliver liquid by compressing a hose or pipe. It works by pressing the hose with a rotating rotor to produce peristalsis, which pushes the fluid forward.
Peristaltic pumps are commonly used to transport liquids containing solid particles or high viscosity, such as sewage treatment, mining and environmental protection industries. Because of its good self-priming capacity and corrosion resistance, peristaltic pumps play an important role in handling complex liquids.
In addition to the differences in working principles, metering pumps and peristaltic pumps are also different in the application environment. Metering pumps are generally suitable for scenarios where high precision metering and precise flow control are required. For example, in the pharmaceutical industry, dosing pumps are often used to dispense medicines and deliver active ingredients. In the petrochemical industry, metering pumps are widely used in chemical process control and regulation. Peristaltic pumps are often used to handle liquids with concentration changes or particles. For example, in sewage treatment stations, peristaltic pumps are used to transport sewage containing solid particles and suspended solids.
In addition, there are also some differences between metering pumps and peristaltic pumps in installation and maintenance. Metering pumps usually require a complex installation process involving connection to the piping system and commissioning of the control system. During maintenance, key components such as the plunger or pulse motor need to be checked and replaced regularly to ensure the normal operation of the pump. In contrast, the installation of peristaltic pumps is relatively simple and usually requires only the proper connection of hoses or pipes. In terms of maintenance, peristaltic pumps need to regularly check the degree of wear of the hose, as well as cleaning and replacing the hose to ensure the normal use of the pump.
In summary, there are some differences between the metering pump and the peristaltic pump in terms of working principle, application environment and maintenance. Choosing the right pump for your application is very important, depending on factors such as fluid characteristics, accuracy requirements and working environment. I hope this article will be helpful to the reader, so that they have a clearer understanding and understanding when choosing the pump.
