Magnetic couplings are used as transmission mechanisms in modern pumps, which makes it possible to obtain a qualitatively new 100% tight device without making essential changes to the design of the electric drive and the wet end of the pump. At present Villina offers GNVC, GNGC and GNVC-P series vertical, horizontal and semi-submersible centrifugal pumps with magnetic couplings, designed for pumping explosive and flammable, toxic and corrosive fluids (petroleum products, alkalis, acids, alcohols, etc). PURPOSE Magnetic couplings for Villina centrifugal pumps allow for transmission of torque from the electric motor to the pump shaft using magnetic fields generated by permanent magnets instead of mechanical engagement devices. At the same time, there is no need to withdraw the shaft from the pump wet end to the drive device, therefore the wet end can be made in the form of a completely sealed system free of leaks which are typical for pumps with mechanical shaft seals.

The magnetic coupling drives for stirring devices are designed to be installed immediately into the tank and provide the necessary stirring of the product. The drive is electrically driven and consists of two half-couplings (driven and driven magnetic half-couplings), bearing assembly and the stirring device itself. Stirring devices (mixers) are of several types: paddle, anchor, propeller, U-type, etc. We develop and supply turn-key solutions for our customers. Magnetic coupling drives for stirring devices are custom-tailored for each specific customer's application in accordance with the sketches provided or according to the parameters specified in the questionnaire form.

Modern petrochemical and gas industries typically use horizontal centrifugal canned pump units with magnetic couplings similar to Villina-GNGC type pumps. They are designed for transiting neutral, corrosive, toxic, as well as explosive and flammable liquids in stationary conditions, the vapors of which can form explosive mixtures with air. Magnetic coupling pumps combine complete tightness, smooth operation, long service life and high maintainability. A sub-type of horizontal pumping units are high-temperature pumps Temperature of the pumped fluid: -50°C to +420°C; viscosity up to 26 cSt; density 2,000 kg/m3 maximum; mass concentration of solid non-abrasive inclusions up to 0.2%; size 0.2 mm maximum Permanent magnets (SmCo) with an operating temperature of up to 450°C are used for operation in these temperature conditions. The pump, a part of the pumping unit, is a single-stage or multi-stage horizontal centrifugal section-type

Centrifugal pumps have well-known advantages such as uniform pumping without surges, the ability to create high pressures at low pump rate in multi-stage designs, long service life and others. However, operation of centrifugal pumps requires building positive pressure (pressure boosting) upstream of the inlet suction pipe for the following reasons: to fill the pump body with the pumped fluid in order to avoid a "dry start" to prevent cavitation during pump operation. Classic methods for creating pressure boosting before centrifugal pumps can be: installation of a tank from which the fluid is pumped, several meters above the axis of the pump shaft and placing the pump in the draw-off sump; inclusion of an additional vacuum pump into the process, which is capable of building the desired pressure boosting of several metres. HOW IS THE PROBLEM OF CREATING A PRESSURE BOOSTING IN MODERN SELF-PRIMING CENTRIFUGAL PUMPS SOLVED? Villina company offers you Villina self-priming GNGC series

The main parts of magnetic couplings used in GNVC series vertical pumps are the driving (external) and the driven (internal) half couplings, and a sealing sleeve between the half couplings. The exceptional reliability of Villina magnetic couplings is the result of a high-tech design: the enclosed capsular design of the half couplings (enclosed body) secures the magnetic systems from environmental effects; the use of special adhesives allows for fast fixture of domestically produced permanent magnets based on rare-earth elements on the half coupling ferrules; double protection against overheating and demagnetization is implemented using the temperature sensor of the sealing sleeve, which is triggered when the maximum acceptable operating temperature is exceeded by 20 to 50°C, with the use of magnets with Curie point of more than 100°C higher than the maximum acceptable operating fluid temperature; the sealing sleeve made of high-strength Hastelloy alloys

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

The Villina GNGC series horizontal canned centrifugal pumps with magnetic couplings are widely used in oil and gas companies of Russia and its neighbouring countries for transit of explosive and flammable, toxic and corrosive fluids. The horizontal arrangement allows the use of a GNGC as a replacement for technically obsolete and physically worn pumps without significantly changing the geometry of the location and pump lines group assembly systems. 100% tightness, structural design in accordance with API 610, 685 (ISO 13709) standards and explosion-proof design of GNGC pumps are approved by design institutes and Rostekhnadzor for use in projects for modernization, reconstruction or construction of new facilities. GNGC horizontal pumps with magnetic couplings provide for axial position of the suction pipe and radial position of the delivery pipe. The motor and pump body are mounted on supports (OH 2 according to API 610), the drive shaft of the motor
