Airless pumps find application in foundries in a variety of contexts. They involve the movement and application of materials in a critical working environment, such as that of a foundry.
Airless pumps are widely prized for their ability to deliver high-pressure fluids precisely through the use of airless guns, making them invaluable in many aspects of machining and production in a foundry. Below, we examine some of the common applications of airless pumps in a foundry:
1 – Spraying of refractory linings: Airless pumps are used to spray refractory linings inside melting furnaces and other equipment. This process protects the exposed surfaces from high temperatures and corrosion, which greatly contributes to extending the life of the equipment.
2 – Applying paints and coatings: Foundries use airless pumps to apply paints, anticorrosive and decorative coatings to metal parts or finished products. This process guarantees uniform, high-quality coverage.
3 – Transporting abrasive materials: Airless pumps demonstrate a remarkable ability to handle dense and abrasive materials, making them useful for pumping sludge and materials containing solids, such as sand, within the working environment.
4 – Transfer of liquid metals: In some foundries, airless pumps are used to transfer liquid metals from one point to another, e.g. during the casting process. The precision and reliability of these pumps are crucial in these applications.
5 – High-pressure cleaning: Airless pumps are also used in high-pressure cleaning of equipment such as ovens. This process effectively removes residues and debris, helping to maintain a safe and hygienic working environment.
6 – Injection of melting agents or additives: In foundries, this type of tool can be used to inject melting agents or additives into metal alloys in order to achieve specific desired properties. Dispensing precision is crucial in these applications to ensure the quality of the final product. In fact, precise airless guns are used for this type of use.
Foundries often require robust and durable equipment, as the working environment can be extremely corrosive and subject to high temperatures. Airless pumps are particularly suited to these challenges due to their ability to deliver high-pressure fluids and their inherent reliability.
The choice of airless pump type and specifications will depend on the specific requirements of the foundry application. The careful selection of equipment is crucial to ensure efficient and high-quality production.
