Product overview
GSN series is our company’s latest high efficiency single stage double suction centrifugal pump. It refers to the world’s best hydraulic model and uses the most advanced hydrodynamic calculation method – CFD (Computer Aided Design) to develop a new generation of pump products.
The pump can complete the company’s vacuum water diversion device to achieve full automatic control, to provide you with a real water supply solution.
Main advantages
The efficiency of GSN pump is the highest in the field of pumps nowadays, which is 3%-5% higher than that of the same products in the same industry. It has higher operating efficiency in a wide flow range. It can reduce operating costs and select motor with smaller power. It is the most energy-saving and high efficiency to start pumps.
GSN pump has excellent cavitation resistance through special design. Compared with traditional double suction pump, it can save capital construction cost.
GSN pump adopts the careful design of reducing noise and vibration, prolongs the service life of equipment, is more economical and environmental protection.
Various material combinations make the GSN pump suitable for a wider range of fields, according to different requirements, choose different material combinations.
Simple structure, easy maintenance
The shell adopts the upper and lower split structure, which is easy to disassemble and easy to repair. As long as the upper shell is disassembled and the main piping is not disassembled, the internal parts of the pump can be repaired.
