Regarding the selection of metering pumps
Thread Content
For the current pilot-scale setup, a metering pump is required. Due to the special properties of the raw material, it needs to be heated to around 80°C before feeding can take place, and the feeding rate needs to be controlled between 50 and 500 g/h I’ve communicated with the equipment manufacturers, and they all said that such pumps are very difficult to find. How should one choose such pumps? Does anyone know? Please give me some advice!
This pump does not provide inlet and outlet pressures. If the pressure is low, a centrifugal pump with a low flow rate and an outlet needle valve can be used to control the flow.
If a plunger metering pump (with slight leakage) is available, the process can be carried out here; it is also necessary to provide: 1. Information on whether insulation measures are required for the pump head and check valves. 2. Viscosity of the medium at operating temperature. 3. Import and export conditions. 4. Requirements for measurement accuracy.

What medium? You can try using a gear pump
