Pump selection, seeking advice
Thread Content
In workshop production, during the desolventization process, the material tends to form particles of size φ1-2; currently, self-priming non-clogging sewage pumps are being used. During use, pipeline blockages often occur due to particle issues. It is hoped that the use of a pump in the future will help avoid such problems; it would be even better if the particles can be broken down. Are there any suitable pumps for this purpose? Or what kind of crushing equipment should be added in front of the pump? (Class A explosion-proof. . . ）
Try a positive displacement pump; one type of such pump is the peristaltic pump, whose mechanical components do not come into contact with the material
A pneumatic diaphragm pump should work; are the particles soft or hard, and what is their size?
The flow velocity within the pipeline is determined through sedimentation calculations; when installing the piping, try to use as few elbows as possible or 45-degree elbows, utilize ball valves extensively, minimize or avoid branches, and a 2900rad centrifugal pump will suffice. You won’t realize how inconvenient it is until you use a self-priming, clog-free sewage pump.
The hose pump mentioned on the 2nd floor is a good solution, but the lifespan of the pipes won’t be very long; it’s necessary to purchase spare ones.
Perhaps a screw pump is a good choice!
Personally, I think it is better to install buffer zones on the pipelines to allow the particles to settle, as particles entering the pump, regardless of the type of pump, will affect its operation
I also personally recommend single-screw pumps~they have good efficiency and are not prone to clogging
You could try a screw pump... The key is Class A explosion protection and good sealing
There should be no problem using a slurry pump. In our company’s wastewater, there are particles, and slurry pumps are used for their transport, with good results. No crushing is required. For reference only
I don’t know either which pump to use to learn* it
