Ours Coated pumps<\/strong> are made with the technology of transfer molding<\/strong> and represent a fundamental part of the production of CDR<\/strong><\/a> with regard to applications in the chemical and pharmaceutical fields.<\/p>\n

These are essential devices for transporting highly corrosive or abrasive fluids: their internal lining of thermoplastic or elastomeric materials guarantees chemical and mechanical resistance, increasing the equipment's operational lifespan.<\/p>\n

Transfer molding\u201c<\/h2>\n

The \u201cTransfer Molding\u201d<\/strong> It is a molding technique that combines elements of compression and injection molding. The polymer material is first heated in a separate chamber and then forced into a closed mold through a runner system.<\/p>\n

This methodology's main result is a high-thickness coating<\/strong>, ensuring superior vacuum resistance compared to other molding technologies such as \u201cRotational molding<\/a>\u201dRotational molding\u201c<\/strong>, which instead uses heat and rotational movement to evenly distribute the plastic material inside a mold.<\/p>\n

Compared to plastic pumps with components machined from solid or made with injection molding, Lined pumps manufactured with Transfer Molding\u201censure greater dimensional stability<\/strong> all various temperatures and also greater resistance to the pressures and loads applied to the suction and discharge flanges. Furthermore, this method reduces the risk of voids or inhomogeneities that could compromise the chemical resistance of the product.<\/p>\n

This therefore refers to a procedure that requires advanced technologies and ensures maximum quality<\/strong> in those more critical environments that require complete isolation of the content, even in very delicate parts of the system.<\/p>\n

The Lined CDR Pumps: Highest quality and safety products<\/h3>\n

\"\"<\/p>\n

The importance of Lined pump<\/strong> In the chemical and pharmaceutical sectors, this led us to implement them by leveraging the technology of the mechanical seal<\/a> What a shame magnetic drag<\/a>. In this way, we can meet the needs of both customers who require pumping of slightly dirty liquids or those with suspended particulate matter, and customers who require more critical and delicate applications, where plant safety and reliability are paramount:<\/p>\n

For mechanical seals, CDR Pompe offers two models:<\/p>\n
