Faster dosing in metering pumps offers several advantages
The IWAKI electromagnetic diaphragm pumps work with up to 360 strokes per minute – ie as many as 6 strokes per second, offering essential benefits in terms of flow, diaphragm and economy.
The short and fast dosing intervals provide a more continuous flow of eg chemicals compared to a slower stroke rate, where a longer stroke length must be used to achieve the same volume.
Repeatability and accuracy are key words in chemical dosing. The dosage amount per stroke is adjusted with the stroke length and the quantity remains the same throughout the dosing process. This helps to optimize chemical consumption.
The technology is actually quite simple as IWAKI’s electromagnetic metering pumps are diaphragm pumps, where the diaphragm is driven back and forth by a solenoid / electric coil and a spring. The solution is good, durable and economical.
IWAKI’s E-pump series (electromagnetic diaphragm metering pumps) offers many control options in terms of both analog and digital controls.

Extended lifetime of the diaphragm
IWAKI Dosing Technology
- Short and fast dosing intervals
- Less stress on the diaphragm
- The life of the diaphragm is extended
The fast stroke rate and the short stroke length on IWAKIs electromagnetic diaphragm pumps minimizes the stress on the diaphragm (diaphragm deformation).
The diaphragm is flexed both backward and forward and thus minimize wear on the diaphragm.
All in all, the life of the diaphragm is optimized.
Other pump types
At a slower stroke rate a longer stroke length is required to achieve the same volume. This results in more stress and wear on the diaphragm.
For some pump models, the diaphragm only moves forward from neutral position, which stresses the diaphragm further and has huge impact on the life of the diaphragm.
