1.Production introduction of Single Screw Pump
● 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.
2.Principles of Single Screw Pump
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.

4.Feature and Benefit
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.
Stainless Steel Rotor
Rubber Rotor
Mechanical Seal
