TGS type energy-saving single stage double suction centrifugal pump technology advantages:
(1) compact structure, convenient disassembly and assembly
The advanced dual suction structure design ensures large flow and high suction. Compared with the traditional dual suction pump, the CS pump system and associated equipment have small footprint. The inner opening design of the shell is easy to disassemble and convenient to overhaul. When the parts need to be replaced, there is no need to move the pump body and the inlet and outlet pipe.
(2) high efficiency and energy saving;
By using the most advanced three element fluid analysis technology, the high efficiency hydraulic model is developed. The efficiency is higher than the previous similar products, and the highest efficiency is 94%. It is 3% to 8% higher than the traditional pump efficiency. The utility model has the advantages of high operating efficiency in a wide flow range, and the use of a smaller power motor to reduce operating costs.
(3) environmental protection
Years of experience of integrated users, the use of patented cooling water take over components and shaft seal water pipe components, to ensure that the pump room clean, no leakage, in line with environmental protection requirements. When the pump runs, the noise is low, the vibration is small, and the comfortable working environment can be ensured.
(4) high transport performance
The excellent hydraulic model, water pump cavitation performance of the pump is excellent, stable operation at a lower level, provide water pump pumping capacity.
