Milton Roy metering pump selection parameters and methods of use

Milton Roy metering pumps are ideal for low flow, low pressure applications and provide good compensation for supply voltage fluctuations.
First, Milton Roy metering pump selection parameters:

1. The flow rate of the liquid being metered.
2. The main characteristics of the liquid being metered, such as chemical corrosivity, viscosity and specific gravity.
3. Back pressure of the system.
4. Appropriate suction height.
5. Other options required, such as analog control, pulse volume control, flow monitoring, and timers.

Second, what are the main advantages of electromagnetic drive metering pumps?

The electromagnetically driven metering pump has only one moving part - the armature shaft. In general, the less moving parts, the more reliable the metering pump will work. Milton Roy metering pumps are ideal for low flow, low pressure applications and provide good compensation for supply voltage fluctuations.
What are the advantages of a fixed-stroke, variable-frequency metering pump compared to a fixed-frequency, variable-stroke metering pump? The amount of stroke per stroke is known by calibration. Therefore, the total dosage can be calculated by calculation (adding amount = frequency per stroke * frequency). The total dosage is linear with frequency (50% frequency = 50% dosage). With external pulse or analog control, the dose can be adjusted from minimum to maximum within one second. In addition, it is much less expensive than the motor-driven stroke length adjustment.

Third. How to use the performance curve of the Milton Roy metering pump?

1. Find the performance graph corresponding to the metering pump you have selected.
2. Mark the current back pressure in the chart below.
3. Determine the correction factor, take the back pressure value in bar, extend up to the curve, and read the correction factor value vertically to the left at the intersection.

Fo. Divide the required dosage value by the corrected factor value to get the value in ml/min. or L/h.
Fi. Place the calculation result in the middle of the dosage scale.
Six. When placing this value on the dosing scale, use a ruler to find the stroke length setting and stroke frequency setting.
