Depo metering pump is a kind of metering equipment commonly used in chemical, pharmaceutical, food and environmental protection industries, with high precision, good reliability and wide viscosity range. However, in the process of conveying liquid, Depo metering pumps will also face various problems, which are described in detail below:

First, pump pipe wear

After using the pump for a period of time, due to the continuous friction, compression and extrusion of the liquid in the pump tube, the inner wall of the pump tube appears wear and corrosion. This wear will not only lead to a decrease in the accuracy of the pump, but also affect the efficiency of liquid delivery and the life of the pump. Therefore, in order to avoid the wear of the pump tube, it is necessary to replace the pump tube regularly, and choose wear-resistant and corrosion-resistant pump tube materials.

Second, scale inside the pump chamber 

When transporting some liquids, such as high concentration solution and viscous liquid, it is easy to form scale and sediment, forming an adhesive layer on the inner wall of the pump cavity, making the inner diameter of the pump smaller, thereby reducing the transportation efficiency of the liquid. At this time, it is necessary to clean the pump chamber to avoid scaling and sediment formation, or use a corrosion-resistant pump material.

Third, the pump pressure is unstable

When transporting some chemically reactive liquids, due to changes in the reaction process, the pressure and temperature of the liquid change, resulting in unstable pump pressure, affecting the accurate measurement of the liquid. At this time, you can use a Depo metering pump equipped with a pressure regulator, or according to the use of liquid requirements, choose other forms of metering pump.

Four, pump pipe leakage

In the process of conveying liquid, if the pump pipe is not tightly connected or the pump head exceeds the specified range, the pump pipe leakage phenomenon will occur. This leakage will not only affect the measurement accuracy of the liquid, but also cause pollution and waste to the working environment. Therefore, it is necessary to pay attention to the installation and use conditions of the pump pipe, and replace the pump pipe in time.

Five, the working noise of the pump is large

When conveying liquids with high viscosity, high concentration, high temperature and high pressure, there will be greater friction between the rotor and the shaft of the Depro metering pump, resulting in a relatively loud working noise of the pump. At this time, measures such as buffer materials and noise reducers can be used to reduce noise.
