The main technical parameters of high-temperature melt pumps are displacement, operating temperature, operating pressure, speed, torque, and drive power, etc. Usually, the displacement, operating temperature and operating pressure are clearly marked on the products of high-temperature melt gear pumps to show that the three parameters of the high-temperature melt gear pump's conveying capacity and pressurizing capacity. In the selection of high temperature melt pump, the displacement multiplied by the pump speed, volumetric efficiency and melt density, to see whether it can achieve the desired larger output. Selection of small displacement melt pump, its economy is better, but the melt pump needs to run at a higher speed, remember that the speed should not be too high, otherwise the melt heating or pump rapid wear and loss.
