Two-component pumps

Two-component injection with airless pumps is a process used to apply materials composed of two distinct components, which are mixed together shortly before application. This method is often employed for applications where it is necessary to ensure adequate mixing of components to achieve the desired material properties.

This is how the two-component injection process with airless pumps works:

1. Two-Component Components: The materials used in this process are composed of two components, often referred to as “Part A” and “Part B”. These components are formulated to react chemically when mixed together.
2. Preparation of the Mixture: The airless pumps are configured to precisely and controlledly dispense the correct quantities of the two parts of the material. Usually, there is a specific proportion between the two components that must be respected to ensure the desired properties of the final material.
3. Mixing: Within the airless pump or at a point near the outlet, the two parts are mixed together. The mixing can take place through a mechanical action or thanks to the pressure generated by the pump itself.
4. Injection: The two-component mixture is then dispensed through the injector of the airless pump. The pressure generated by the airless pump helps to inject the material in a uniform way, even in the presence of considerable back pressure, in depth.
5. Spraying: The two component mix is then dispensed through the airless pump spray gun. The pressure generated by the airless pump helps to spray the material evenly on the desired surface.
6. Cure and Reaction: Once applied, the material begins to react chemically. This reaction can include processes such as polymerization or hardening, which lead to the solidification of the material and the development of the desired properties such as strength, adhesion and durability.

Two-component injections with airless pumps are used in a variety of applications, such as:

• Structural Repairs: In the construction industry, two-component grouts can be used to repair cracks, fissures and structural damage on surfaces such as cement and concrete.
• Construction of Joints and Gaskets: This process is used to create sealed joints, gaskets and hermetic connections in applications such as the marine industry, the chemical industry and civil engineering.
• Waterproofing Applications: Two-component injections can be used to apply waterproofing materials in places such as underground utilities or areas subject to water infiltration.
• Repairs of Industrial Equipment: In the industrial setting, this process can be used to repair equipment and components that require specific mechanical or chemical properties.
• Applications in the Electronics Industry: Two-component injections can be used to seal and protect electronic components from moisture, dust, and contaminants.

The use of airless pumps for two-component injections allows accurate control of the quantities of each component and ensures homogeneous mixing before application, guaranteeing consistent and high quality results.
