Regarding the selection of slurry, grout, and mortar pumps?
Thread Content
1. I’ve never really understood the differences between these three types of media: slurry, sludge, and mortar. Is the difference the particle size and fluid viscosity? 2. For the selection of such pumps, apart from open impeller centrifugal pumps, what other types are recommended? 3. How can a single pump supply water to 3 identical spraying devices, ensuring that the flow rate and head delivered to each device are equal and that the spraying occurs simultaneously?
Diaphragm pumps are very suitable for various media with high solid content, high viscosity, and abrasive properties, such as slurries, mortars, and sludge. Diaphragm pumps can be used in applications where the flow rate is not very high but the pressure is high.
I’m helping you move to the mobile device section for more communication; more people are welcome to participate in the discussions in various sections of the technology forum
There is no air supply at the site; although the first thing that came to mind was a diaphragm pump.
Diaphragm pumps come in both pneumatic and electric types; those that are pneumatic generally have lower pressure. Electric diaphragm pumps can achieve relatively high pressures, with maximum values exceeding 100 bar
