Single-stage Double-suction Centrifugal Pump

The single-stage double-suction centrifugal pump is a high-efficiency, high-flow-rate clean water pump. It adopts a double-suction symmetrical structure and is widely used in municipal water supply, industrial circulating water, air conditioning systems, and fire protection engineering.

For example:
GSX150-280MA

GSX  Series designation
150  Discharge (outlet) diameter (mm)
280  Nominal impeller diameter (mm)
M   Indicates a modified small impeller (standard impeller is unmarked; "N" denotes a modified large impeller)
A   Impeller trim code ("A", "B", and "C" indicate the first, second, and third trim levels, respectively)

High Efficiency, Low Energy Consumption

Double-suction symmetrical impeller design ensures uniform water flow distribution and balanced axial force, improving efficiency by 5-8% and significantly reducing operating energy consumption.

Low Noise, Low Vibration

Symmetrical impeller and thickened pump body design effectively counteract vibration sources.

Durable

Pump body options include cast iron, ductile iron, and stainless steel. Diverse shaft seal configurations are available to suit clean water and mildly corrosive media.
