This series of pumps are single stage and double suction centrifugal pumps. The flow range is 188 ~ 1476m3/H: The pumping head is 16 ~ 75m, and the temperature of the medium does not exceed 105 ° C. It is mainly used for the central air -conditioning system. It is also suitable for various drainage occasions.

This series of pumps have adopted foreign popular structures in recent years. Compared with the open structure in the horizontal, firstly the same wall thickness and material can withstand higher static pressure (three 1.6MPa); secondly, The axis is only mechanically sealed, shortening the distance between the impeller to the shaft seal and the axis seal to the bearing, so the axial dimension of the pump is also significantly shortened.

The NS single stage double suction split case  pump is our company's summary of the excellent hydraulic models at home and abroad, extensively absorbing the advanced design and manufacturing technology of similar products at home and abroad, and developed a new type of open -style double -suction pump based on the actual needs of the domestic market. The planning of all models in the entire series of pump types is more scientific and reasonable. The high -rise dual -suction pumps can replace some multi -stage pumps. Large -flow dual pumps can replace some mixed pumps to optimize the size of all hydraulic size, take into account both auto erosion and efficiency, and meet GB /T19762 Energy Evaluation value, achieve energy -saving goals.

The structure is re -innovated, the operation is reliable and easy to maintain, and the service life is extended, so that the outstanding pump type of the Chinese open -style dual -suction centrifugal pump is more effective. The dual pumps currently produced by our company have 46 models and 390 specifications. They are considered in energy saving and use performance. One model has two impeller, called standard impeller and narrow leaf wheels to meet the requirements of the use conditions with better performance. This series of pumps meet the ISO2548C, GB3216, GB/T5657 standards.
