Pumps for low flow rates
Thread Content
I would like to ask what kind of pump is suitable for low-flow applications? Could you recommend some manufacturers? Thank you
How small? That’s a bit too general – flow rate, medium, head? ?
There are many manufacturers of chemical process pumps; you can search for them on your own. Just inform them of the operating conditions, and that’s all.
It depends on the head required. Generally, metering pumps are used, but vortex pumps and high-speed pumps can also be chosen
A metering pump will suffice for dozens of kilograms. What is the medium? Viscosity? Diaphragm pumps or piston pumps work fine; there’s no need to consider head pressure.
Pneumatic diaphragm pumps, vortex pumps, etc., are suitable for low flow rates, but all relevant conditions must be considered: flow rate, head, medium, viscosity, density, etc
The original poster’s concept isn’t very clear. Flow rate is just one aspect; head pressure, the chemical properties of the material, specific gravity, viscosity, and suction conditions are all very important. Pumps for low flow rates include pneumatic diaphragm pumps, metering pumps, magnetic pumps, etc.
Pneumatic diaphragm pumps, metering pumps, and magnetic drive pumps all have relatively high prices. Are there any pumps that are cheaper yet still meet the required performance standards?
