First, an overview: SFG-type single-stage single-suction pipeline centrifugal pump is the selection of domestic excellent hydraulic model, using IS centrifugal pump performance parameters, based on the general vertical pump designed to be clever combination, while SFG Based on derived from the applicable hot water SFGR, low-speed SFGD. The series has high efficiency, low noise, reliable performance. Second, the main purposes: ①SFG, SFGD vertical pipeline centrifugal pump for the transport of water and physical and chemical properties similar to other liquids used in water, suitable for industrial and urban water supply and drainage, high-rise building pressurized water, garden sprinkler, fire by Pressure, long-distance transport, HVAC refrigeration cycle, bathroom and other heating and cooling water cycle pressure and equipment support, the use of temperature T <80 ℃. ②SFGR type vertical hot water (high temperature) circulating pump is widely used in: energy, metallurgy, chemical industry, textile, papermaking, hotels and restaurants boilers and other high-temperature hot water circulating pump and urban heating system circulating pump, the use of temperature T <120 ℃. Third, the main features: SFG pump flow range 1.5-1280m3 / h, lift 8-125m, can replace the conventional centrifugal pump used in all occasions. Low noise, low vibration: The pump and the motor shaft are absolutely concentric, the impeller has excellent balance, ensuring high-speed operation without vibration, short axial dimensions, so that the pump noise is very low. Solve the noise caused by the conventional centrifugal pump coupling, vibration and other issues. Fourth, the working conditions: System pressure 1.6Mpa, that is, the pressure of the pump population of 10 pump head ≤ 1. 6Mpa, pump test pressure 2.4Mpa. For the transport of water or physical and chemical properties similar to the water of the liquid. Medium temperature: SFG, SFGD T <80 ° C, SFGR T <120 ° C. Please specify when ordering system working pressure, pump working pressure greater than 1.6Mpa should be made separately, in order to manufacture, the pump overcurrent parts cast steel material.
