Product Description General Type N NB NBA GN GNL3 Serial big flow gland type Condensate Water Pump/Condensation Pump are single-stage single-suction overhanging centrifugal condensate pumps.Type GN GNL pumps are double-stage single-suction centrifugal condensate pumps.They are used for transferring condensate water from the condensator or the turbo generator of 750-3000KW in power station as well as turbogenerator other liquid which is physically and chemically similar to water.The temperature of the liquid is below 80°c.Inlet pressure is not allowed more than 0.6MPa. Performance range Capacity Q:11~120m3/h Head H:12-143m Description of pump type Example 1 100NB--45 100--Inlet diameter of pump(mm) N--Condensate pump B--Overhanging type 45--Designed head(m) Example 2 GNL3--A GNL3---B G--High head N--Condensate pump L--Vertical type 3--Inlet diameter is 3 inches A,B--Diameter of impeller is changed Structure Chart Construction of Type N NB Serial Big Flow Gland Type Condensate Water Pump/Condensation Pump Type N NB NBA GN GNL3 Serial big flow gland type condensate transfer pump are horizontal type and GNL pump is vertical type.The pumps use rolling bearings which get lubricated with grease.The shaft seal is either packing seal or mechanical seal. The direction of rotation The rotation of pump rotor is counter clockwise looking from the motor to the pump. The material of main parts of Type N NB Serial Big Flow Gland Type Condensate Water Pump/Condensation Pump The medium-contacting parts,i.e.pump casing,cover,seal ring and shaft sleeve are made of cast iron. The material of impeller and inducer of type N is separately silicon brass,aluminium-ferro-bronze. The material of shaft is high-quality carbon steel. Complete provision range Pump,motor,coupling,check valve and sluice valve. Company Information
