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?

The magnetic system of this field source is also built on the principle of nested cylindrical Halbach-structures. An important feature is the presence of two motors, controlled independently, so it is possible to manage the change not only the magnitude but also the direction of the magnetic field. Because the device was designed for operation together with an optical microscope, the vertical size of the system near the working region is reduced to 90 mm. Stepper motors, that turn the two magnetic subsystems, are located on the sides of the casing Working bore diameter:36 mm Size of the homogenous field area:Ø20 х 20 mm Maximal field:1.05 T System mass:40 kg

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 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.

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
