Pump selection

Question: For a flow rate of 1-2 cubic meters per hour and a head of 250 meters, which pump should be chosen? Thank you!
It is necessary to indicate the medium and viscosity. Low flow rate and high pressure are suitable for plungers, for reference.
The head is not low; you can try a multi-stage centrifugal pump.
Factors like the medium, as well as other elements, need to be taken into account
If the flow rate is not high but the pressure needs to be high, choose a vertical booster pump with multiple stages connected in series
First, determine the properties of the material, such as its density and viscosity. For pumps that require low flow rates but high head pressures, piston pumps, metering pumps, or Hamlin’s multi-stage shielded pumps can be used
High-speed pumps: 11 models are available, and Tiande ones work as well. Screw pump, Nippon Kikai, or Seals can be used; multi-stage pumps won’t work. Plunger pumps tend to break easily.
For pumps with low flow rates but high head, it is recommended to select them in the following order of priority: high-speed pumps, multi-stage pumps, and reciprocating pumps.
