VVN-type liquid-packed ring vacuum pumps Rambler's Top100

The pumps are designed for suction of air or inert gases insoluble in water as well as aggressive gases not producing corroding effect on the pump flowing part materials.
The inlet gas pressure is up to 0,01 MPa, the outlet one is atmospheric. They can be used for suction of dust-laden gases with content of solid particles of no more than 0,1 mm size and little water content.
The flowing part for pumps VVN2-50M, VVN2-150M and VVN2-300 is made of grey cast iron and carbon steels, for pumps VVN1-12TM and VVN1-50TM - of titanium alloys, for VVN2-50N and VVN2-50H - of corrosion-proof steels.
