Single Screw Pump - Industrial Pumps Manufacturers & Suppliers

Single Screw Pumps Manufacturers

Single Screw Pumps are a type of rotary Positive Displacement Pumps. These pumps are the best choice for transfer of liquids requiring smooth and non-pulsating flow. These pumps are known for their high suction ability. Single screw pumps cater to a number of industries including shipping, chemical, ceramic, paper, waste water, paint, oil & gas and many more. These pumps can efficiently handle the transfer of abrasive and non-abrasive liquids, with and without solid particles such as sewage, sludge, bilge and foods such as jelly, yeast and ketchup. These pumps offer very low life cycle cost. Also single screw pumps are non-clogging.

Single Screw Pumps are reversible. These pumps work on the principle of positive displacement. These pumps comprise of a single helix metallic rotor and double helix elastomer stator. The liquid is pumped through suction port. As the rotor moves inside the stator, cavities are formed. The liquid moves along the cavities due to positive displacement and gets discharged from the discharge port of the pump.

Pumping Principle

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.

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.
