Magnetic - Import export

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.

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
