Protection. The second offers improved working conditions for leveling drawings, machining and assembling. Main functions are protection against wear and tear, reducing the risk that abrasive materials may produce lethal "Dest" Or make everything so polluted it wont work on a made-in series projection (mip) system, ensuring a smooth flow of fluids. With advanced material technology, dvt pump sleeves use the latest in materials designed and manufactured to fit extreme temperature and pressure environments. These high-performance protective measures are a few steps ahead of traditional coatings and linings. They are generally used in industries such as mining, petrochemistry, food processing and pharmaceuticals, whenever the operation of pumps must be both reliable and long lived.
