Selection of low-flow, high-head pumps
Thread Content
Operating conditions: Medium pH 13, slightly muddy; flow rate of 2 m3/h, head pressure of 350. What type of pump would be suitable for these conditions?
For high-head pumps, piston pumps are generally chosen, and the working medium for piston pumps must be a clean liquid. It’s better to start by finding ways to study medium purification.
Piston slurry pump; Plunger slurry pump
Can shielded pumps and submersible pumps work?
Are shielded pumps or submersible pumps feasible?
It seems that the head capacity of these two types of pumps you mentioned is not sufficient to reach 350m. The names of these two pumps do not indicate the way in which they operate. Pumps can be roughly classified into centrifugal pumps, screw pumps, gear pumps, piston pumps, and so on. The applications of these pumps also have corresponding names; for example, submersible sewage pumps are mostly centrifugal pumps, but they can also be diaphragm pumps or other types.
A diaphragm pump is a suitable choice, as it offers low flow rate and high head pressure.
With such a low flow rate, series connection isn’t an option for now; well, it seems that a plunger pump will have to be used. I don’t know what the lifespan is like
Now that the head needs to be reduced to below 100, what kind of pump would be suitable?
