Can the peristaltic pump run dry?

Peristaltic pump is a type of pump equipment widely used in industrial and chemical fields. It has attracted much attention due to its unique working principle and characteristics. When using peristaltic pumps, people often ask an important question: can peristaltic pumps run dry? This article will explore this issue in detail and provide relevant details and information.

Let's understand the working principle of peristaltic pumps. The peristaltic pump utilizes a compressed hose to achieve fluid delivery. It generates a series of continuous peristaltic effects by compressing and releasing the hose, thereby pushing the liquid to the desired position. The working principle of a peristaltic pump determines that it requires the presence of liquid to provide necessary lubrication and cooling during operation.

In many industrial applications, OEM peristaltic pumps typically require continuous operation to meet production needs. However, in some cases, whether a peristaltic pump can operate dry becomes an important issue when there is no liquid supply. Dry operation refers to whether a peristaltic pump can operate normally without liquid or with insufficient liquid supply.

According to the design and manufacturing of peristaltic pumps, most of them can currently operate dry to a certain extent. This is mainly due to the development of modern technology and materials. Modern peristaltic pumps use high-quality hoses and materials that can withstand the risk of high wear and tear for a certain period of time. Therefore, peristaltic pumps can operate dry for a short period of time, but it is not recommended to operate dry for a long time to avoid problems that may cause equipment damage.

It is worth mentioning that the dry running ability of specific peristaltic pump models and brands may vary. Some high-quality peristaltic pumps may have stronger durability and wear resistance, allowing for prolonged dry operation within certain limits. However, even high-quality peristaltic pumps still require regular inspection and maintenance during dry operation to ensure their normal operation.

Dry operation may have a certain impact on the peristaltic pump. Firstly, pump micro creep may generate higher temperatures without liquid cooling and lubrication. This may lead to thermal expansion and increased thermal stress of pump components, thereby increasing the risk of equipment damage. Secondly, peristaltic pumps may experience poor sealing or pump head blockage during dry operation, which may lead to a decrease in pump performance or even complete shutdown.

To avoid these issues, we recommend maintaining a liquid supply at all times while the peristaltic pump is running. If the liquid supply is interrupted or insufficient, timely measures must be taken, such as stopping the pump or providing temporary liquid supply. Regular inspection and maintenance are also key to ensuring the normal operation of peristaltic pumps. This includes checking the degree of wear on the hoses, ensuring the cleanliness of the pump head and seals, and regularly replacing severely worn components.

In summary, peristaltic pumps can operate dry to a certain extent, but long-term dry operation is not recommended. Dry operation may cause damage and performance degradation of the pump. In order to ensure the normal operation of the peristaltic pump and extend its service life, it is very important to always maintain liquid supply and regular inspection and maintenance.
