Which type of pump is better to choose based on the following conditions?
Thread Content
The fluid for the pump is lubricating oil, and high and uniform pressure is required. I don’t know which type is good to choose. Could everyone give some advice? Thank you~~~~
I’m not sure if a screw pump is suitable
A gear pump is a more suitable choice; the oil pumps in hydraulic stations are all gear pumps.
Could you tell me about the working principle of screw pumps and their characteristics? Thank you! ~~
The working principle of a screw pump is that as it operates, the screws rotate while meshing with each other; the liquid is then driven by the helical grooves on one or several of these screws and discharged in an axial direction. Its features include compact scaling, virtually no pulsations in flow rate and pressure, stable operation, long service life, as well as a limited range of applicable liquids and viscosities.
