Sludge Pump Manufacturers
Sludge pumps are used for transferring highly viscous solid laden liquid with minimal water content. Roto pumps have a rich history in supplying progressive cavity pumps for deposit transfer applications. Due to this premium 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, and this category of pumps both can transfer highly viscous media 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 liquid.
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.

Progressive Cavity Pumping Principle
Roto Pumps is a noted Progressive Cavity Pumps manufacturer. High Pressure Progressive Cavity Pumps are also known as Single Screw Pumps, these pumps have been built and designed to transfer liquids with different chemical properties and variable viscosities. These pumps can be customized as per the application requirement. These pumps function with the help of precision mechanized single external helix metallic rotor and double internal helix elastomer stator. The fluid gets transferred through the cavities formed by the turning of the rotor within the stator.
The working principle of these pumps involves the rotation of the single helix-shaped rotor within the stator. A sealing line is developed along the axis of the rotor owing to the positioning of the rotor and the stator, which upholds in both static and compelling conditions. Several cavities are formed along the suction and the discharge end of the pump by the rotation of the rotor. These cavities transfer the fluid within the pumps.
Because of single rotating element, progressive cavities are generated which deliver a uniform, metered and non-pulsating flow. The developed head is independent of the rotational speed, where as the capacity is proportionate to the speed.
Inherently self-priming, the pumps can work on snore and do not require a foot valve.
Can handle solid in suspension or media containing a high percentage of solids.
Low NPSH Requirement
Suction lift capabilities of up to 9.5mWc and effective in high vacuum conditions.
Low Internal Velocity
Minimum degradation of shear-sensitive media, and can also handle highly viscous materials having pseudo-plastic characteristics.
Due to the reversible rotation capabilities, Progressive Cavity Pumps can perform with equal efficiency in either direction.
Rotors turn inside a resilient stator and thus generate little noise.
Separate Bearing Housing
Fluids can be pumped without no contamination.
