Thickened Sludge Pumps

Sludge Pumps is a type of Positive Displacement Pumps that are designed to handle the flow of combination of waste water liquids or different types of sludge with solid concentration. Due to their use in difficult applications, these kinds of pumps are built with strong and robust materials. The industries which actively use these kinds of pumps are municipal sewer treatment, ETP plants, biogas plants and waste water plants.

These Thickened Sludge pumps works on the principle of progressive cavity pumps where a single helix metallic rotor rotates inside a double helix elastomeric stator to form cavities along the axis. The liquid is transferred through these cavities from suction to discharge end of the pump. These pumps are also available with hopper and bridge breaker arrangement on application requirement. Also, these pumps are customizable to suit customer’s application requirement. Roto Thickened sludge pumps are non-clogging due to their unique design and work fine in low NPSHR conditions as well.

Progressive Cavity Pumping Principle

The pumping element comprises of a precision machined single external helix metallic rotor, and a double internal helix elastomer stator. Due to the special profile of the rotor and stator set, a sealing line is formed along the axis of the rotor which is maintained at both static and dynamic conditions. As the rotor turns within the stator, these cavities progress from the suction to the discharge end of the pump carrying the fluid.

Positive Displacement
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.

Self priming
Inherently self-priming, the pumps can work on snore and do not require a foot valve.

Non-Clogging
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.

Reversible
Due to the reversible rotation capabilities, Progressive Cavity Pumps can perform with equal efficiency in either direction.

Silent Running
Rotors turn inside a resilient stator and thus generate little noise.

Separate Bearing Housing
Fluids can be pumped without no contamination.
