The kerosene chemical industry occupies a very important position in the national economy, and chemical process pumps, as supporting equipment, are also receiving increasing attention. How to correctly select the model of chemical pumps is of utmost concern to users. Due to the complex characteristics of chemical media and the continuous improvement of user requirements, how to select and what aspects should be focused on? It appears particularly important. This article provides a comprehensive summary of the material selection, conveying medium, and sealing issues of chemical pumps. The conveying medium includes two aspects: medium type and medium viscosity, which are expected to be more helpful for customers in selecting chemical pumps.

Chemical pumps are widely used for industrial and urban water supply and drainage, as well as for irrigation and drainage in farmland and orchards. They are used to transport clean water or other liquids with physical and chemical properties similar to clean water.

Chemical pump modelThe principle of choice.

1Make the selectedChemical pump modelThe performance meets the requirements of process parameters such as device flow rate, head, pressure, temperature, cavitation flow rate, and suction.

2It must meet the requirements of medium characteristics.

For pumps that transport flammable, explosive, toxic, or valuable media, reliable shaft seals or leak free pumps such as magnetic drive pumps, barrier pumps, and shielded pumps are required.

For pumps transporting corrosive media, it is required that the convection components use corrosion-resistant materials, such asAFBStainless steel corrosion-resistant pump,CQFEngineering plastic magnetic drive pump.

For pumps transporting media containing solid particles, it is required to use wear-resistant materials for convection components, and if necessary, clean liquid flushing should be used for shaft seals.

3High mechanical reliability, low noise, and minimal vibration.

4Economically, it is necessary to consider that the total cost of equipment, operation, maintenance, and management fees is very low.

The above is a summary of the principles for selecting chemical pump models, hoping to be helpful to everyone.
