Liquid transfer pump
Thread Content
I’m seeking advice from experts: for my factory, we have liquids with a melting point of 90° and fine particles in them. What type of pump is suitable for use? Rotary pumps can get clogged due to these particles, while piston metering pumps experience wear on their valve balls after prolonged operation because of the small diameter of the pipeline nozzles. Neither of these two types of pumps can be used; moreover, a pump with a flow rate of just 200 L/h would be sufficient. Thank you all.
It is recommended to check whether the slurry pump has such a minimum flow rate; oh, you haven’t mentioned the head (exit pressure) yet.
System pressure and head are very important; they need to be considered comprehensively

The outlet pressure of the pump is not specified, nor are the temperature and viscosity of the fluid being transported provided. If a rotary pump can be used, the pressure of the pump is likely to not be very high, within 0.6 MPa. It is recommended to use a insulated gear pump with external bearings, and then reduce the pump’s rotation speed through frequency conversion or a matching reducer. Feel free to leave a message if you have any questions.
Yes, I feel the same way!
With such low flow rate, it is recommended to use a diaphragm pump
Check on Taobao to see how diaphragm pumps are, for reference.
