CB Type NB, NBA, GN, GNL, N Condensate Pump
NB and NBA pumps are single-stage single-suction cantilever centrifugal condensate pumps. GN and GNL pumps are two-stage single-suction centrifugal condensate pumps, suitable for power plants, used to pump condensate in condensers and 750~3000 kW steam turbine generator sets to pump condensate or other liquids with physical and chemical properties similar to water. The liquid temperature does not exceed 80 ℃. The pump inlet pressure is not higher than 0.6 MPa.
NB, NBA, GN, N are horizontal, GNL is vertical. Rolling bearings are used, grease is used for lubrication, and the shaft seal is a packing seal, or a mechanical seal.EMAC will continue to update the product introduction pages of different standard versions of pumps.
