Slurry Pumps manufacturers
Roto Pumps is a leading Slurry Pumps manufacturers and suppliers. Slurry pumps are also know as Progressive Cavity Pumps or Single Screw Pump. These pumps are heavy-duty pumps built and designed to transfer waste — liquids containing solid particles or a concentration of solids. They are made with robust material in order to handle both abrasive and non- abrasive fluids. Slurry pumps are used in a number of industries such as mining, sugar, paper and wastewater etc. They are also suitable for pumping a variety of liquids such as crude oil, mud and paints. These economical and low-maintenance pumps can be customized as per the requirements of the applications.
These pumps primarily consist of a single external helix metallic rotor, and a double internal helix elastomer stator. When the rotor moves inside the stator, cavities are formed from suction to discharge and the fluid moves through these cavities.
These kinds of pumps are ideal for applications involving viscous, abrasive and gentle types of media. They are also extremely economical to maintain and easy to clean. Their parts are easily replaceable in case of any wear and tear caused due to the corrosive nature of the fluid. An extremely useful feature of these pumps is that they are non-clogging in nature, that means they don’t get clogged easily due to the presence of solid elements in the liquids. They are also reversible and are capable of working in low NPSHR conditions.
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.
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.
