2BV water ring vacuum pump type determination To determine the model of 2BV water ring vacuum pump, we should first determine which series of pump to choose according to the process parameters of the device, the physical and chemical properties of the conveying medium and other parameters, combined with the structural characteristics and applicable station of our company's products; then determine the rated flow of 2BV water ring vacuum pump; thirdly, we should also determine its rated head; and then determine the 2BV water ring vacuum pump Rated motor.When determining the model of 2BV water ring vacuum pump, you should also check the type spectrum of the selected series of pumps, the corresponding flow and head in which model box. At this time, you can preliminarily determine the selected model. Usually, under different speeds, you may choose one model. For checking the performance curve of the initially selected model, check whether the NPSHr of the pump is consistent Meet the npsha requirements of the unit.When selecting 2BV water ring vacuum pump, pay attention to check the performance curve and check whether the rated working point of the selected model falls in the high efficiency working area of the pump. The final model of 2BV water ring vacuum pump is determined by comprehensively comparing the efficiency, speed (the lower the speed, the longer the service life) and price of the pump.CL Sereis Cone Liquid Ring Vacuum PumpRoots BlowersRoots Vacuum Pump
