External Foam Pump plays a key role in many industries. Its main function is to convert liquid into foam through mechanical action. It is widely used in cleaning, chemical, agricultural, laboratory and other fields. However, in practical applications, leakage is one of the common faults of External Foam Pump, which not only affects the normal operation of the equipment, but also may cause potential harm to the environment and operators. Therefore, it is crucial to deeply analyze the cause of leakage and propose practical solutions.

Cause Analysis of Leakage Problem
Aging or Damage of Seals: The seals used in External Foam Pump (such as O-rings, sealing rings, etc.) work in liquid environment for a long time, which is prone to corrosion, wear and aging, resulting in decreased sealing performance and eventually leakage.
Loose connection parts: If the connection parts between the pump body and various components (such as flanges, threads, etc.) are not fully tightened during installation, or loosen during long-term use, liquid leakage will occur.
Cracks in the pump body or components: Due to insufficient material quality, harsh use environment or long-term excessive pressure, cracks may appear in the pump body or some key components, which will lead to leakage.
Improper operation: When using the External Foam Pump, improper operation, such as over-tightening the connection parts, using inappropriate tools, etc., may cause leakage problems.
Liquid corrosion: Some liquids are corrosive to the pump body or seals. Long-term contact may cause damage to the materials, which in turn causes leakage.

Solution to leakage problems
Replace aged or damaged seals: Regularly check and replace aged or damaged seals in time to ensure good sealing performance. When selecting seals, consider their corrosion resistance, wear resistance and high temperature resistance to adapt to different working environments.
Tighten the connection parts: Regularly check the connection parts between the pump body and each component to ensure that they are tightened in place. Use appropriate tools and methods for tightening to avoid over-tightening or damaging the connection parts.
Repair or replace cracked parts: For cracked pump bodies or components, they need to be repaired or replaced in time. During the repair process, choose repair materials that match the original component materials to ensure that the repaired components have sufficient strength and sealing performance.
Standardized operating procedures: When using the External Foam Pump, strictly follow the operating procedures to avoid leakage caused by improper operation. At the same time, operators should be trained to improve their operating skills and safety awareness to ensure the safe operation of the equipment.
Select corrosion-resistant materials: For corrosive liquids, it is recommended to use corrosion-resistant materials to manufacture pump bodies and seals to extend the service life of the equipment and reduce the risk of leakage.

Preventive measures and suggestions
Regular inspection and maintenance of External Foam Pump is the key to ensure its long-term stable operation. By timely discovering and dealing with potential problems, the failure rate of equipment can be effectively reduced. In addition, when selecting accessories such as pump bodies and seals, attention should be paid to their quality and performance, and products with reliable quality and excellent performance should be selected to ensure the overall performance and safety of the equipment.
