General informations |
|
| Anti-abrasion centrifugal pumps can be covered in rubber or made of very high resistance alloy. They are horizontal axis pumps with rotor shaft supported by 2 grease lubricated bearings, for heavy duty. Open impeller covered in rubber or alloy with very high abrasion resistance suitable for pumping abrasive liquids. Double mechanical seals with pressurized external flow. High percentage of pumpable dry matter. The rubber compounds for the covering depend on the application needs. The lining shells are replaceable. | |
Applications |
|
|
In the ceramic sector they can be used for pumping the slip in the production process or for disposing of the sludge produced during processing.
In the processing of marble, granite and stone in general, both in quarries and in laboratories or sawmills, water has multiple applications. From cutting to polishing, water is necessary to avoid overheating of work tools and reduce the dust produced during the various procedures. The water must then be treated to be reused in a closed production cycle or to be safely discharged into the environment. Due to their applications, aggregates, such as gravel and in particular sand, need to be washed to recover the fine material and eliminate the sludge that remains attached to their surface. Usually, the water used for washing the sand can be recycled through the use of settling lakes in which the heaviest particles end up at the bottom and are then recovered and stored. In the mining sector, different types of abrasive and acidic liquids are handled, such as sludge, waste and waste water, our pumps provide excellent solutions and reliability in every situation. In order to recover the water and cement residues at the end of the processing cycle, the water used for washing trucks and concrete mixers must undergo treatment. Our pumps are also suitable for this sector with very aggressive water and mud. In glass factories, water is treated to remove the residue created during glass processing. The environmental reclamation sector is the sector dedicated to the recovery of material deriving from soil crushing and washing processes. The material must be washed to remove the polluting part, decontaminating it. An important application is for the recovery of construction materials. Pumps for chemical plants are designed, built and coated to withstand the pumping of aggressive and corrosive liquids of all kinds and types. Our pumps are used in urban organic waste collection systems. These are food residues or food preparations and similar fractions, such as food paper soiled with food residues. |
