What information is needed to properly select a metering pump? 1, is the measurement of liquid flow. 2, was measured the main characteristics of liquids, such as chemical corrosion, viscosity and specific gravity. 3, the system's back pressure. 4, the appropriate suction height. 5, the other options needed, such as analog control, pulse control, flow monitoring and timer. What are the main advantages of electromagnetic driven metering pump? Electromagnetically driven metering pumps have only one moving part - the armature shaft. Generally, the less moving parts, the more reliable the metering pump works. Metering pump is ideal for low-flow, low-pressure workplaces, and good compensation in the supply voltage fluctuations. And fixed frequency, change the stroke length of the metering pump, the fixed stroke length, change the frequency of the metering pump What are the advantages? By calibration, the dosing amount for each stroke is known. The total dosage can therefore be calculated (dosing = dosing per stroke * frequency). The total dosage is linear with frequency (50% frequency = 50% dosing). Through external pulse or analog control, dosage can be transferred from minimum to maximum in one second. In addition, it is much less costly than motor-driven stroke length adjustment. Want to know more? Shengzhou Weidelong Pump Co., Ltd., we give you more ~
