NB, NBA, GN, GNL, N type condensing pump Summary: NB, NBA type pump, is a single - stage single - suction cantilever centrifugal condensing pump. GN and GNL type pump are two-stage single-suction centrifugal condensing pump, suitable for power plant, used for pumping condensate in condenser and 750 ~ 3000kW turbo generator unit for pumping condensate or other liquids with physical and chemical properties similar to water. The liquid temperature does not exceed 80℃. Pump inlet pressure shall not be higher than 0.6mpa. Parameters: flow Q 11 ~ 12 ~ 36 m3 / h head h 62 m model description: NB 100-45, 100 - the pump inlet diameter for mm N - condensate pump B - suspension frame 45 - the design of the pump head high m GNL3 - A GNL3 - G - B N - condensate pump suction L - vertical 3 - pump inlet diameter of 3 inches of A and B, two different structural type of impeller diameter: NB, NBA, designed.the GN, N be horizontal, vertical GNL. Using rolling bearing, grease lubrication, shaft seal as packing seal, can also be mechanical seal. Direction of rotation: The pump rotates counterclockwise from the motor end. The main parts material: the pump body, the pump cover, the seal ring, the shaft sleeve material is cast iron, the N-type condensing pump impeller is silicon brass, the induction wheel is aluminum iron bronze. The shafts are of high quality carbon steel. Complete range: complete supply pump, motor, coupling, check valve, gate valve. When ordering, please indicate the material of main parts, if you have special requirements for pumps and motors, you can negotiate with our company about the technical requirements.
