OverviewType NDX pump is applicable for pumping clean water and
liquids whose physical and chemical properties are similar to water
and without solid particles.This series of products can be used in
factories,mines,urban water supply and drainage,HAVC,industrial
softened water and farmland irrigation and drainage,etc.It can also
be used in pressure stabilization and water supply systems of urban
fire control.Pump with the same specification can change the
performance parameters by cutting the outer diameter of the
impeller;the normal speed of the pump is 1450RPM and 2900RPM, if it
is required to operate at the maximum speed of 3550RPM(60Hz power
supply or with gasoline and diesel engine),our company can provide
technical instruction on the change of the outer diameter of the
impellerThe type NDX pump features simple structure,reliable
performance,small volume,light weight,high efficiency,good
ati-cavitation performance, low power consumption and convenient
use and maintenanceThe pump is suitable for pumping medium at
temperature of -10~85ºC and working pressure of 1.0MPa,if
there is a need to increase to 1.6MPa or higher,please specify when
selecting and orderingPerformance Parameters

efficient: Applying the most advanced NRCE design software and
CFD fluid simulation software to develop and design the high
efficiency hydraulic model,through the analysis of pump flow
field,temperature field and strength,thermal
deformation,fracture,rotor dynamics,etc,to achieve high efficiency
,reliability and wide efficiency zone,we have made the pump satisfy
the efficiency and reliability requirements of centrifugal pump
operating under design conditions and non-design conditions,
reaching the international advanced level.Rear opening type
structure:The maintenance is convenient,It is not necessary to
disassemble the suction and discharge pipes during maintenance to
pull out the rotor parts for maintenanceQuality assurance:Before
casting,the imported chemical analysis of the materials was carried
out by the direct reading spectrum analyzer introduced from Britain
to ensure that the material composition meets the requirement.The
pump impeller and rotor components are tested by precise dynamic
balance test,so the pump can run more smoothly, have less vibration
and noise and longer service life.Product orientation:Improve the
technical level of the domestic equipment industry, effectively
serve equipment and processes to meet the needs of
safety,reliability,energy conservation and environmental
Protection.Structural FeaturesPump casing:Footing support
structures,base support structure.The pump intakes axially and
discharges from the top end.The spiral volute can bear up to 2.5Mpa
of pressure.The flanges at the inlet and outlet can be drilled
according to the metric system or the American systemImpeller:The
closed impeller adopts excellent hydraulic model design to ensure
the performance and efficiency of the pump.The impellers are 100%
tested by dynamic balance test to reduce the vibration of the
pumpPump shaft:The pump is equipped with SS420 stainless steel
shaft,which has wide versatility.There are more than 60
specifications in the whole series,while only six kinds of shafts
are used.The same specifications of shafts,bearding,shaft
sleeves,shaft seals and impeller fasteners can be interchangedShaft
seal:It adopts high quality mechanical seals from well know
domestic manufactures,the seals have long service life and no
leakage,and can be equipped with auxiliary systems such as flushing
and coolingBearing:It is imported NSK bearing that ensure a longer
service life.The double closed,maintenance free bearding eliminates
the need for separate lubricants,saving the time for
maintenance.FAQ1. Q:Are you a manufacturer or trading company
A:We are a manufacturer that specializes in industrial pump
for 60 years 2. Q:What payment term do you
prefer? A:Normally we take payment term 30% T/T in advance,70%
paid before shipment, we can also accept L/C at sight. 3.
