Diaphragm pump and peristaltic pump are two common types of pumps in the industrial field, and there are some differences in their use mode, working principle and application scenarios.

First of all, diaphragm pumps and peristaltic pumps are different in the way they are used. A diaphragm pump is a discharge pressure pump that is pushed through a diaphragm in the pump body. The peristaltic pump is a displacement pump that pushes the medium out by rotating the roller. In a diaphragm pump, the medium is transmitted through the diaphragm inside the pump body, while in a peristaltic pump, the medium is transmitted through the interaction between the roller and the pipe.

Secondly, the working principle of diaphragm pump and peristaltic pump is also different. The diaphragm pump realizes the transmission of the medium by compressing and releasing the diaphragm, so it has the characteristics of no gas and no leakage. Peristaltic pump is through the rotation of the roller so that the medium in the pipeline is squeezed out, suitable for conveying high viscosity and easy crystallization of the medium.

Again, the application scenarios of diaphragm pumps and peristaltic pumps are not exactly the same. Diaphragm pump is suitable for the transport of various media, especially suitable for the transport of corrosive and granular media. Peristaltic pump is suitable for conveying high viscosity media, such as mud, sludge and so on.

In addition, diaphragm pumps and peristaltic pumps also have some differences in performance. Diaphragm pumps usually have a larger flow rate and a higher discharge pressure, which is suitable for larger transportation needs. The peristaltic pump has a smaller flow rate and lower discharge pressure, which is suitable for smaller transportation needs.

In summary, there are some differences between diaphragm pump and peristaltic pump in the use mode, working principle, application scenario and performance. When choosing which pump to use, it needs to be determined according to the specific needs and media characteristics.
