High Efficiency Single Stage Double Suction Centrifugal Pump

General
Type GSX series product is characterized by broad comprehensive performance
curve,sound hydraulic performance, novel structure,high efficiency,high
reliability,low net positive suction head ,and low maintenance.
The design,manufacture,and quality of this series product meet the standard of
GB/T5656”Technical conditions for centrifugal pumps-Class II”and its
efficiency indexes meet the standard of GB/T19762”The minimum allowable values
of energy efficiency and evaluating values of energy conservation of
centrifugal pump for fresh water”

Application
GSX series products are mainly used for transport fresh water or other liquid
with similar physicochemical properties to fresh water,it can also be widely
applied in water supply and drainage system or circulation cooling water system
for steel,petrochemical,thermal power generation,mining,and other working
conditions
