One mechanical seal pump<\/a> it is one of the preferred choices for its reliable performance and ability to operate in harsh environments, making it ideal for many industrial and commercial applications.<\/p>\r\n\r\n\r\n\r\n

Its main strength is the design that allows fluids to be kept separate in two distinct environments, preventing any communication between them. In the electric pumps<\/a>, the mechanical seal allows the rotating shaft to come into contact with the fluid without causing leakage. For this reason, sealing systems are installed between the shaft and the pump housing, ensuring resistance to friction and effective pressure control.<\/p>\r\n\r\n\r\n\r\n

Let's now examine this type of pump in detail, its benefits, and its main characteristics.<\/p>\r\n\r\n\r\n\r\n

Mechanical seals for pumps: operation<\/h2>\r\n\r\n\r\n\r\n

A mechanical seal pump like the ones present in the CCL line of CDR Pompe<\/a>, represents an evolution compared to older pumping systems, overcoming their limits of resistance and productivity. In this type of pump, the mechanical seal acts as the interface between the static part (the housing) and the dynamic part (the shaft) of the pump.<\/p>\r\n\r\n\r\n\r\n

The rotating section, which connects to the shaft, is sealed by an O-ring, an annular seal made of elastic materials and available in various sizes. This seal is designed to accommodate deformation and ensure an effective seal.<\/p>\r\n\r\n\r\n\r\n

Systems of Mechanical seal for pumps<\/a> generally include three contact points: two on the static part and one on the dynamic part, near the rotating shaft, which is particularly critical. This last element is essential for the system's effectiveness and comprises a surface with two bearings, one fixed and one rotating, designed to reduce friction. The bearings are kept under pressure and stabilized by a spring, thus preventing fluid leakage.<\/p>\r\n\r\n\r\n\r\n

To ensure proper operation and prevent wear, bearings must be constantly lubricated with a fluid film during use. The distance between the bearings must be very precise, around 1 micron, to allow for smooth, frictionless movement and prevent leaks.<\/p>\r\n\r\n\r\n\r\n

Single or double mechanical seal pump<\/h3>\r\n\r\n\r\n\r\n

A mechanical seal pump can be either single or double, like the models present in our UCL line<\/a>.\u00a0<\/p>\r\n\r\n\r\n\r\n

The main difference between a single mechanical seal pump and a double mechanical seal pump lies in the number of sealing surfaces and their arrangement.\u00a0<\/p>\r\n\r\n\r\n\r\n

Here's an overview of the differences:<\/p>\r\n\r\n\r\n\r\n
