How to choose such a pump?
Thread Content
For production needs, the head required is 20~30 meters, and the flow rate only needs to be 30~60 liters/Hr (note: Hr). Please advise.
Could you please indicate what medium flows inside the pump? The selection of the pump is determined based on the medium, pressure, and other factors
I wonder what the pump used by the original poster is for? Peristaltic pumps are used in the pharmaceutical industry, generally for spray granulation. Pumps with low flow rates include plunger pumps or metering pumps.
- -#Speechless. 1. The flow rate is too low; adding a flow meter and a control valve will do. There are many options when it comes to selecting pumps. Moreover, for a flow rate of 30–60 L, the cost of choosing an appropriate flow meter isn’t low either. Of course, if one makes a glass tube flow meter themselves, the cost will be lower – around 500 yuan per unit. 2. It’s better to have a storage tank nearby (the daily volume required is less than 1.5 m3); use a high-level tank system, fill it up at once, and then let the liquid flow out slowly. This way, the issue of selecting a pump can be avoided.

I’m not sure what material you intend to transport. Based solely on the parameters you provided, magnetic-driven micro gear pumps can be used; the T series pumps have a minimum flow rate of 19 L/h and a maximum flow rate of 2460 L/h, while the D series pumps have a minimum flow rate of 0.06 L/h with a head range of 3.5 Bar to 17.2 Bar (provided by Thayer Group’s Shanghai office).

Based on the information provided by the poster, a positive-displacement pump can be chosen; however, to finalize the model of the pump, detailed specifications such as the pressure, temperature, viscosity, corrosivity of the medium, as well as the cost of the equipment, are required.
A metering pump can adjust the flow rate and also measure it. Depending on the medium, a plunger type or diaphragm type can be selected.
Bingo! It’s used for spray granulation. Could you tell me something about the pump types that can be used for this purpose?

Axial flow metering pumps are good options; they are suitable for accurate measurement of low flow rates, and can be used with a wide range of media.
