Sludge Pump Manufacturers

Sludge pumps are used for transferring highly viscous solid laden sludge with minimal water content. Roto pumps have a rich history in supplying progressive cavity pumps for sludge transfer applications. Due to the sludge transfer capability, these pumps are also known as sludge pumps. Roto Progressive Cavity pumps are used in municipal water treatment plants, commercial water treatment plants, biogas plants and effluent treatment plants. The wide throat progressive cavity pump with bridge breaker arrangement is capable of handling sludge with up to 40% solid particles. As far as performance is concerned, Roto progressive cavity pumps or sludge pumps can transfer sludge at capacity up to 420 m3/hr or 1850 GPM and pressure up to 48 bar or 696 PSI. These parameters can vary depending upon viscosity of the sludge.

These pumps offer superior performance and efficiency. These pumps operate with the help single external helix metallic rotor & double internal helix elastomer stator and when rotor start rotating inside the stator, it form cavities through which liquid is transferred as result of positive displacement.  These pumps are becoming the best choice for several industries such as mining, wastewater, biogas, paper, paint, explosives etc.
