Selection of pumps for special locations
Thread Content
Selection of pumps for special applications: 1. Flow rate of 5–10 L/min; used for pumping from pipelines containing gas in the intermediate stage, where gas and liquid are mixed later on； 2. The liquid mixture contains a significant amount of particulates; those that can settle through free sedimentation are no larger than 10 mm, with many small particles present ； 3. For export-foldable filters, the pressure increases after use, reaching up to 0.2 MPa. Experienced users are requested to recommend a suitable type of pump.
For the mixed transport of gas, liquid, and solid substances, twin-screw pumps are the preferred choice for transporting gas and liquid. However, they are not suitable when solids are involved. Nevertheless, such pumps still require external lubrication and drive systems; the best option in this case is a cam-rotor pump. I am a manufacturer in this field, and the original poster can leave their contact information so that we can communicate
Various rotary positive displacement pumps should offer different pump types to choose from, but the presence of solids is a major problem; even if they can be used, their service life won’t be long~~~ It’s recommended to use a pre-treatment step such as sedimentation or cycloning before using these pumps~~~ That would make a big difference~~~ Oh~~~ Sinusoidal pumps could be considered as an option~~
Take a look at the single-screw pump: it can transport gas-liquid mixtures as well as media containing solid particles
