Under what circumstances should a screw pump be used?
Depending on the properties of the medium, those containing particles are generally suitable options
For substances with high viscosity, such as heavy oil and residue, screw pumps are required; screw pumps are also used for transporting slurries.
The applicable range of screw pumps is specified in the documentation, and it can also be found online
This question is difficult to answer; there is a great deal of detailed information available online. There are many types of screw pumps, and countless different operating conditions
Generally, they have a high viscosity; when there are many particles in the material, a screw pump can be considered as an option. For example, screw pumps are used as the transfer pumps for transporting the product obtained from gypsum-based flue gas desulfurization to vacuum filters where the gypsum is dehydrated.
Transporting high-concentration, high-viscosity slurries with <10000 PaS and containing particles.
If particles are present, a triple-screw pump cannot be chosen. The viscosity of the medium is generally between 1 and 100,000 cst. And it is non-corrosive.
