Snake Pumps Manufacturers
Snake Pumps are built and designed to efficiently handle the transfer of thick and highly viscous fluids. These pumps are also known as single screw pump or progressive cavity pumps. These pumps are an ideal choice to transfer liquids with varied viscosities, abrasiveness and with solid concentration. These pumps are capable of maintaining a uniform flow of the liquids. The speed of these pumps can also be manipulated as per the required flow of fluids. In these pumps, pressure is inversely proportional to flow of the pump.
Roto’s Snake Pumps are a kind of Positive Displacement Pumps. Their primary parts consist of a rotor and a stator. The material from which the stator is built depends upon the requirement of the application. Usually synthetic rubber like elastomer or fluoro-elastomer are used in its construction. The rotor is made from stainless steel, hard-coated stainless steel or hard-coated carbon steel. It is usually built in the shape of a helix.
When the rotor starts rotating inside stator, it form cavities which help in transfer of liquid from suction to discharge. Roto’s snake pumps are non-clogging, reversible and have low NPSHR and low internal velocity. These pumps are customized based on application requirement.
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.
