Vertical Single-Stage Suction Centrifugal Pumps

Overview Type 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 impeller The 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 maintenance The pump is suitable for pumping medium at temperature of -10~85â?? and working pressure of 1.0MPa,if there is a need to increase to 1.6MPa or higher,please specify when selecting and ordering Performance  Capacity: 5-1650m3/h  Head: 5-135 m Product Features Energy 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 maintenance Quality 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.

Os series single-stage double-suction split volute centrifugal pump Os axially split pump overview: Model os pumps are single-stage double-suction inter opened spiral casing centrifugal pumps.It is used to water transportation in water plants, air conditioning water circulation, building water supply, irrigation, drainage pump station, electric power station, industrial water supply system, fire-fighting system, and shipbuilding and so on. Os axially split pump material: Pump casing:casting pig, ductalloy, cast steel; Impeller: bronze, casting pig, silicon brass, stainless steel; Shaft: stainless steel, carbon steel; Seal-ring on pump casing:bronze, casting pig, silicon brass, stainless steel. Os axially split pump feature: 1. It has compact structure, nice appearance, good stability and it is easy to install; 2. The optimally designed and stable running double-suction impeller makes the axial force reduced to the minimum and it has a blade-style of excellent hydraulic performance. Both internal surface of the of the pump casing and the impeller's surface are extremely smooth after being precisely cast.They have a notable performance on ovapour-corrosion resisting and a high efficiency. 3.Bearing use skf and nsf bearings to guarantee a stable running, low noise ande long duration. 4.Shaft seal use burgmann mechanical or stuffing seal to ensure a 8000h non-leak running. 5.Installation does not need to adjust when assembly and it can be vertically or horizontally assembled upon the conditions of use on the spot.
