Magnetic coupling pumps - Import export

Gear pumps with magnetic coupling The magnetic coupling is equal to contact-free drive and seal. Magnetic coupling pumps are used if critical media has to be transported. The seal ensures that the pumps work 100% securely and without leaking. The magnetic coupling is particularly ideal for hazardous substances that should not escape into the enviroment. The coupling is hermetically sealed and can be designed with different sensors for monitoring and in different variations and materials. A magnetic coupling is used in combination with a chemical pump by default.

Universal drive control for utmost efficiency MAGSON magnetically coupled centrifugal pumps are extremely efficient by nature. Using the SFU frequency converter for optimum adjustment to changing conditions, this efficiency will increase even more. Thanks to leading-edge control technology, the SFU permanently adjusts the discharge rate to specific requirements. Whenever the rate has to be reduced or the pump has to be operated with changing volume flows, using a frequency converter will save you lots of money. Thus, the power required by a pump running at half speed is only 12% of the original demand. So the system operates with optimum efficiency but saves a lot of energy, especially in part-load operation.

Depending on the scrubbing liquid, they can be used for caustic or acidic vapors. Gas scrubbers are equipped with an ETFE lined, corrosion resistant magnetic coupled pump. The flow rate of the scrubbing liquid can be controlled with the built-in reducing valve. The scrubbing liquid temperature is maintained by a spiral cooler in the liquid circuit.

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

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

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 MPN Pump Series is particularly suitable for crystallizing media (no air can get inside), toxic or environmentally hazardous media.
