Electromagnetic diaphragm metering pump
Characteristics
1. Electromagnetic metering pumps have only one moving part—the armature shaft. Generally speaking, the fewer moving parts, the more reliable the metering pump.
2. Electromagnetic metering pumps are ideal for low-flow, low-pressure applications and offer excellent compensation for power supply voltage fluctuations.
3. Compared to fixed-frequency, variable-stroke metering pumps, fixed-stroke pumps, through calibration, provide a known dosage per stroke. Therefore, the total dosage can be calculated (dosage = dosage per stroke * frequency).
4. The total dosage is linearly proportional to frequency (50% frequency = 50% dosage). Control is via external pulse or analog control.
