High Pressure Slurry Pump

Roto Pumps is a leading High Pressure Slurry Pumps manufacturer and supplier. These kinds of pumps are built to transfer slurry- a semi- liquid combination of solid particles and fluid. The nature of these pumps makes them an ideal choice for various industries such as chemical, pharma, food, cosmetics, paper, paint etc. The robust quality of these pumps enables them to handle the transfer of varied kinds of liquids including mud, paints and crude oil. These kinds of pumps are extremely customer-friendly as they can are easy to clean and maintain.

Roto slurry pumps are a subtype of positive displacement pumps and work on the principle of progressive cavity pumps where cavities are from by rotary action of helix metallic rotor inside double helix elastomeric stator. The slurry is then transferred through these cavities from suction to discharge as a result of positive displacement. These pumps are ideal for liquids with varied viscosities, abrasiveness and other chemical compositions. These pumps can easily provide flow rate of 2200 GPM and pressure up to 696 PSI. Also, these pumps can be reversely operated and are non-clogging due to their unique design. Roto slurry pumps works fine in low NPSHR conditions as well.

Pumping Principle

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.

Features & Benefits

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.
