Vertical semi-submersible pumps are designed to solve the problem of pumping liquid out of a tank when a part of the pump is within the pumped medium. Pump units are used with the engine speed up to 3,000 rpm. Therefore, the temperature conditions for semi-submersible pumping units are up to 250 degrees. Centrifugal semi-submersible pumps are widely used both in petroleum refining (petroleum and drainage pumps) and the chemical industry, and in the food industry. They are used for transit of various liquids and mixtures including explosive and flammable fluids (oil and gas products, etc.). Semi-submersible pumps are in between surface and submersible units and combine all their advantages, nevertheless, a semi-submersible pump is not designed to carry out specialized tasks for which these two types of units were created. Semi-submersible pumps consist of an electric motor, a working section and immersed sections. The engine is placed on a base plate

One of the priority areas in the production of Villina pumping equipment was initially the development of a specialized line of pumps designed for pumping harsh chemical fluids. At present, we are ready to offer you Villina high-end lined centrifugal canned pumps having design life of 20 years for pumping mineral and organic acids, alkalis, salts, oxides and anhydrides, including chlorides, as well as alcohols, esters, aromatic hydrocarbons, ketones, aldehydes and other media which contain various concentrations of mordant substances. Modern technology makes rapid progress, and in place of pumps used earlier for transit of corrosive fluids made of chemically resistant yet expensive steels such as KhN65МV, N70MFV, 06KhN28MDT, lined pumps are widely used now. In accordance with para. 51 of the Safety Rules of chemically hazardous production facilities, corrosion-resistant non-metallic coatings (polyethylene, fluoroplastic) can be used to protect equipment and pipelines
