This series of pumps are single stage, double suction centrifulgal pumps, the capacity of this pump ranges from 30 to 1900 m3/h, the head ranges from 3 to 145m, the temperature of the medium should no more than 105?, this type of pump is used in central air-conditioning system, and aslo used for water supply and drainage.The series of pumps are designed by adopting polular structure abroad recently, compared with horizontal split-casingstructure, the new structure has many advantages, firstly?can stand with higher static pressure(=1.6Mpa), under the condition of same wall thickness and materials; Secondly, shaft seal only use mechanical seal, shorten the distance from impeller to shaft and the dictance between shaft seal and bearing, so shorten the axial size of the pump observably.
