Sludge pump selection issues
Thread Content
Having seen the discussions on forums regarding sludge pumps, my personal experience is that 1) for materials with a high moisture content, such as over 99%, centrifugal pumps or double-suction pumps can be used； Because pumps are easy to repair and buy ； 2. For those with a moisture content of around 97%, an eccentric screw pump can be used; however, the spare parts are expensive, so brands such as Nippon or Seppick are generally chosen ； 3. Currently, rotor pumps can be used to replace screw pumps
Slurry pumps and screw pumps are my first choices when designing
A screw pump is not necessary if there is no sludge thickening tank; it should be used if there is a sludge thickening tank.
I agree with what was said above: generally, screw pumps are used for fluids with high viscosity, while centrifugal pumps are more efficient for fluids with low viscosity.
Screw pumps have low viscosity, while centrifugal pumps are efficient – not bad.
I still support what was said on floor 4 – centrifugal pumps give better results
The original poster is right; it’s practical experience
A screw pump is generally used – a small sludge storage tank is installed
In general, a centrifugal pump is the better choice as it is more convenient to use
"For those with a high moisture content, such as over 99%, centrifugal pumps or double-suction pumps can be used； Because pumps are easy to repair and buy – that’s a good point! I feel the same way!
It’s really enlightening; everyone has the same opinion. Let’s give it our support~!
If there are no special requirements, a centrifugal pump is the better choice – it has a low cost and high efficiency. Screw pumps have strong stability
My recommendation is to use a sludge pump, as it is designed for transporting materials with large particles and high viscosity. We have used screw pumps in the past for transporting materials similar to water, but the outlet pressure never reached a high level (that is, it did not reach the designed head), so we eventually stopped using them. Centrifugal pumps are still better in performance, cheaper, and easier to maintain.
A manufacturer came by this morning, but it seems she knows very little about this technology. In the future, more materials of this kind could be sent over. Thank you, Xue*!
Slurry pumps and screw pumps are supported.
A screw pump is not necessary if there is no sludge thickening tank; it should be used if there is a sludge thickening tank.
Agree with what was said above; pneumatic diaphragm pumps are also being used quite frequently these days
Pneumatic diaphragm pumps are also used quite often; they offer support, and I’m using one of them right now.
