Industrial motor pumps - 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.

Villina-VS1-M type pumps are designed for use in oil and gas and chemical industries for transit of explosive and highly flammable liquids as well as corrosive media and natural gas liquids. A distinctive feature of these pumps is the ability to transit contaminated liquids with particle size of 3 to 12 mm (depending on the pump rate). MAIN SPECIFICATIONS - Pump rate ranges: 2 to 108 m3/h; - Head: 11 to 178.5 m; - Temperature of the pumped fluid: -50°С to +440°С.

ADVANTAGES - GNVC-P vertical semi-submersible pumps are developed and manufactured according to individual parameters of the Customer and in compliance with normative documents. - Time of manufacture: 90 days. - Warranty period: 24 months. - Chemical pumps are capable of pumping liquids with viscosity up to 35 cSt, and density up to 2,000 kg/m3. PERFORMANCE SPECIFICATIONS - Purpose: transit of corrosive, toxic, explosive and flammable fluids; - Pump rate ranges: 1 to 55 m3/h; - Head ranges: 5 to 250 m; - Seal type: a magnetic coupling according to API 685 with a sealing sleeve made of Hastelloy alloy (standard version) ensures 100% tightness; - Temperature of the pumped fluid: up to plus 250°С; - Shaft speed: 2,900 rpm; - Structural design: type VS4 according to API 610, vertical type, fixed installation on the container neck on the base plate; - Submergence: 1 to 6 metres, with a length increment of 10 cm for the choice of a specific immersed part length of the pump.
