The design of an electric pump section is similar to the design of a standard vertical electric pump with a GNVC series magnetic coupling, which allows for the use of already proven technical solutions: impeller blades with curved surfaces create an angle of attack and partially allow for switching to the laminar mode of wall-adjacent flow on their surface and provide more efficient deflection of liquid to the periphery; a closed type impeller has a higher efficiency and longer service life compared to open and semi-closed impellers; bell-type fit of the impeller on the pump shaft precisely keeps the geometric position of the impeller with respect to the guide vanes; the vertical position of the shaft resting on a heavy-duty carrying cushion in the vertical plane, and sleeve type bearings in the horizontal plane help prevent sagging of the shaft, as for instance, in the horizontal design of the pump, and play and runout; the use of sleeve type bearings

Villina-GNVCP-2T type vertical electric semi-submersible pumping units are designed for transit in stationary conditions of neutral, corrosive, toxic, as well as explosive and fire hazardous liquids, the vapors of which can form explosive mixtures with air. These are used in gas, petrochemical, petroleum refining and other industries. The vertical semi-submersible pump – the pump part is fully or partially in the pumped liquid. The unit consists of a pump part, drive sections, a base plate, a device that transmits torque from the drive, an electric motor (drive). The ground part comprises a console fastened to the base plate, an electric motor mounted and fastened to the console, and a mechanical seal support system fastened to a base plate. The semi-submersible part comprises drive sections fastened to the base plate, an elastic coupling body connected to the lower drive section, a pump connected to the elastic coupling body and a discharge line.

Our products include Villina-GNGC-2T type centrifugal horizontal pumps with tandem mechanical seals type according to your parameters. These are used for transit in stationary conditions of neutral, corrosive, toxic, as well as explosive and fire hazardous liquids, the vapors of which can form explosive mixtures with air. The units are mainly used by petrochemical industry companies. Parameters of operating fluids (liquids): temperature from -50oС to +400oС viscosity up to 160 cSt density 2,000 kg/m3 max, with a high concentration of particles particle size over 0.2 mm, but not exceeding free passage of the impeller (3 to 12 mm depending on the pump rate) For such conditions, mechanical seals (operating temperature up to 425°C) of well-known companies are used, such as: OOO NPC ANOD, JSC TREM ENGINEERING, UNICHIMTEK Group of Companies and others DESIGN FEATURES The unit consists of a pump, a base plate, an electric motor, a casing and a support system.

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
