In this blog we want to explain you the specifications and advantages. Are you ready? What is the LSC41? LSC41 specifications Environmentally friendly LID eCONTROL technology What is the mechanical seal LSC41? The mechanical seal LSC41 is an evolution of the LSC40 cartridge, a seal that have proved a great reliability and versatility in many applications. It has been tested successfully by many clients from different countries and sectors! By comparison,…

  The food concentrates industry is one of the most powerful sectors in Southern Europe. There are many plants dedicated to manufacturing concentrated products such as tomato, citrus fruit, milk, sweets, alcoholic beverages and aromatic essences, among others. The concentrate production process consists basically of eliminate the water presence in the raw material to obtain a product with extremely intense properties. At the same time, their volume and weight are reduced by more than 90%, which facilitates their transportation and storage. What is more, concentrated products can be stored for long periods of time without spoiling and without their properties…

As we already saw in previous blog entries, agitators/reactors are a very special type of machine that is usually involved in the main processes of many facilities. This type of system requires mechanical seals that provide the highest level of service. In some cases, apart from the usual requirements for agitators to be able to operate in dry conditions, at high temperatures and with axial/tangential force, there are other, more demanding requirements such as being in contact with extremely aggressive chemicals or abrasive substances. The agitators that operate under these conditions usually have enamel-coated interiors and they are known as…

Agitators are of the most common industrial systems. They can be used in practically any sector, with the chemical and food industries being those in which this type of machinery is used most. There are many agitator/mixer designs with a greater or lesser degree of complexity, but they all have a common basic concept; they are used in tanks or similar devices into which different substances are poured and stirred using a rotating paddle system to mix them. Reactions usually occur between the added products, and for this reason these mixtures/reactions must remain under controlled pressure and/or temperature conditions. Again,…

When a process implies working with chemically very aggressive fluids, our systems’ components must be prepared for it, including mechanical seals, thus avoiding their becoming of the weak link in the installation. Acid and alkaline solutions in very high concentrations are common both in the chemical and food industries. In the automotive sector, for example, decanting pumps of acids, such as hydrochloric and sulphuric, can be found as mordants to strip metal plates destined to bodywork. In the paper industrya multitude of alkaline, such as sodium hydroxide, and acid substances, like chlorine dioxide and hydrogen peroxide, are used to obtain…

It is known that a mechanical seal is a complex device in its design, assembly and functioning. Nevertheless, its efficacy does not often depend on any of the aforementioned points but on another one, which is not always considered: the state of the installation of mechanical seals for pumps. The state of the installation and the shaft where the seal must be assembled is determining for the mechanical seal’s proper functioning. It is common for these components of the pumps to suffer from wear and damage at the time of the repair. The first element that must be revised to…

Often, work conditions under which a sealing system must function can be very demanding: high pressures, extremely elevated temperatures, paste-like or chemically corrosive products, high frequency and intensity vibrations, etc. In the face of extreme conditions, a peak performance sealing system is required, such as our range of metal bellows mechanical seals. ADVANTAGES OF METAL BELLOWS MECHANICAL SEALS: These kinds of seals characteristically have a metal bellows instead of a spring/springs in order to maintain the strength between friction faces. Metal bellows present some advantages in relation to conventional spring systems (simple springs, multisprings or wave springs): · Increased capability…

The industrial refrigeration sector requires very complex and special systems and machinery, there even are specific products and solutions for each application. The most characteristic element of industrial refrigeration systems is the compressor. It compresses the refrigerating fluid and makes it circulate so it can absorb the heat from the space that needs to be refrigerated. If you wish to know more, you can consult the following PDF about our industrial refrigeration compressors. Characteristics of industrial refrigeration compressors • High frequency vibrations. – They can endure high frequency vibrations, even over 4000 hz. • High pressures. – Compressors work in full…

  Itt is becoming more and more common for companies to set up preventive maintenance models, with planned stops that overtake production stops, failing of parts, and thus, fluid leaks. This enables companies to avoid emergency repairs. Therefore, it is fundamental to have not only the mechanical seal technically most adequate for appliance, but also the spare parts and resources to offer its repair. ADVANTAGES OF MECHANICAL SEAL REPAIRS It increases life cycle   Mechanical seals can be repaired, which means their life cycle is longer, considerably reducing maintenance costs.   The possibility of an improvement in design   Thanks…

To correctly define the cost of maintaining a system, it is necessary to consider all the relevant issues, in order to make the best decision about which elements to use and how. When sealing a pump, this exercise is even more complex compared to other systems. This article explains all the aspects that must be taken into consideration when selecting two of the sealing elements that are mostly used in pump maintenance: braided packing and mechanical seals, especially cartridge seals. Level of efficacy of a mechanical seal as opposed to braided packing The first aspect to be considered is the…

The LWS31 model is a high performance mechanical seal in technological and hygienic terms. The basis for its design is the LWS30 mechanical seal which is known for its balancing system, making it possible to work comfortably at pressures of up to 35 bar (500 PSI). The rest of the design has been reviewed and optimised with respect to hygienic criteria. One of the great advantages of the LWS31 seal is its assembly length according to EN12756 (KU) standard, eliminating the need for manufacturers to have to modify the design of their pumps. Nonetheless, in the event of having to…
