Food Grade Micro Electric Dosing Peristaltic Pump

Do peristaltic pumps need check valves?

Whether a Mini DC Peristaltic Pump needs to be equipped with a check valve depends on the specific usage scenario.

Under normal working conditions, the Peristaltic Pump only transports material in one direction, and there is no backflow of material. Therefore, it is not necessary to install a check valve. However, in some special cases,

For example, when conveying relatively viscous or easy-to-agglomerate substances, a certain amount of material will remain in the pipeline and pump chamber. These materials can easily flow back after the pump stops working, causing negative pressure in the pump.

Or the pumping situation will seriously damage the normal operation of the pump. At this time, installing a check valve can effectively avoid this situation.

Therefore, for normal use, peristaltic pumps do not need to be equipped with check valves. However, for special usage scenarios, in order to protect the normal operation of the pump, you can consider installing a check valve.

How to choose a check valve for a Small DC Peristaltic Pump?

When selecting a peristaltic doing pump check valve, you need to consider the following factors:

1. Material: Select the appropriate material according to the transported medium to avoid reaction or corrosion with the medium. For example, if corrosive media is transported, corrosion-resistant materials such as polytetrafluoroethylene should be selected.

2. Structure: The structure of the check valve should be simple, lightweight, and easy to clean and replace. At the same time, the sealing performance of the valve must be good to ensure a good sealing effect.

3. Connection method: According to the usage requirements, different connection methods can be selected, such as flange connection, threaded connection, etc. At the same time, attention should be paid to the sealing performance of the joint.

4. Working pressure: The working pressure of the check valve should match the working pressure of the DC Circulating Peristaltic Pump to ensure normal use.

5. Working temperature: For transporting high-temperature media, high-temperature-resistant check valves should be selected.

Technical Specification

Are peristaltic pumps quiet?

The noise level of Micro DC Peristaltic Pump is usually less than 70dB, which is a low-noise device. Compared with traditional peristaltic pumps, micro peristaltic pumps use more advanced technology and materials, resulting in less noise during operation.

Micro peristaltic pumps usually push fluid flow through a cam or scraper in a peristaltic hose. This movement method may produce a certain amount of vibration and noise. The Micro diaphragm pump uses a diaphragm

It uses reciprocating motion to transport fluid. Relatively speaking, its noise generation mechanism is relatively simple, so the noise level may be lower.

However, the specific noise level is also affected by many factors, such as equipment model, operating conditions, fluid properties, etc. Therefore, in actual use, it is necessary to compare the two

Evaluate and compare the noise levels of various devices. If you need more detailed information, it is recommended to refer to the noise data provided by the relevant manufacturers or conduct field testing.

What is the lifespan of a DC Electric Peristaltic Pump?

The life of a Micro Peristaltic Pump will be affected by many factors, such as equipment model, usage environment, maintenance conditions, etc. Generally speaking, under the proper use and maintenance conditions of a high-quality micro peristaltic pump, the life of the DYX micro peristaltic pump is more than 30,000 cycles, starting for 30 seconds and stopping for 10 seconds.
