Selection of centrifugal pumps
Thread Content
Is there a centrifugal pump with a flow rate of 0.1 cubic meters per hour? ? ?
The smallest one I’ve seen was 1.1; I’ve never seen one that was 0.1.
The metering pump should be able to meet this requirement
HDX low-flow chemical centrifugal pump: ● Flow rate (Q): 0.1–12 m3/h ● Head (H): 20–160 m ● Temperature (T): -80°C to +350°C ● Pressure (P): up to 1.6 MPa
I’ve never seen a centrifugal pump with such low flow rate; can a metering pump be used as a substitute? Such as piston pumps, diaphragm pumps, etc
Search on Google for: centrifugal pump, low flow rate, 0.1 – there are many results! ! PY,……
Why not choose other types of pumps? Centrifugal pumps with such low flow rates have very low efficiency, making them uneconomical to use. The various types of pumps developed are designed to meet the needs of different operating conditions, with the aim of achieving energy efficiency and economic viability.
For such a low flow rate, it is recommended to use an imported pump
I can only choose a micro centrifugal pump, but I’ve never seen one
There are micro centrifugal pumps, but they are also quite expensive. I recommend using metering pumps
It is recommended to use a plunger pump with pulse feeding
