Knoll single screw pumpIt is a rotary positive displacement pump. These pumps are the best choice for delivering liquids that require smooth and non-pulsating flow. These pumps are known for their high suction capacity. Single screw pumps are suitable for many industries, including shipping, chemicals, ceramics, paper, wastewater, paint, oil and gas, and more. These pumps can effectively handle the delivery of abrasive and non-abrasive liquids, with or without solid particles such as sewage, sludge, bilge water and foods such as jellies, yeast and ketchup. The life cycle cost of these pumps is very low. Single screw pump will not clog.

Single screw pump is reversible. These pumps operate on a positive displacement basis. These pumps consist of a single helix metal rotor and a double helix elastomer stator. The liquid is pumped out through the suction inlet. As the rotor moves inside the stator, a cavity is formed. The liquid moves along the chamber due to positive displacement and exits from the pump outlet.

Knoll Single screw Pump Advantages:

1. Positive displacement

Thanks to a single rotating element, a progressive cavity is created to provide a uniform, metered, and pulsation-free flow rate. The development of the head is not related to speed, because the capacity is proportional to the speed.

2. Self-absorption

Self-priming in nature, the pump can work during snoring and does not require a bottom valve.

3, no blockage

It can handle solids in suspension or media containing a high percentage of solids.

4, low NPSH requirements

Suction capacity up to 9.5mWc, effective in high vacuum conditions.

5, low internal speed

Shear sensitive media have minimal degradation and can also handle high viscosity materials with pseudoplastic properties.

6. Reversible

Due to the reversible rotation ability, the screw pump can operate with the same efficiency in either direction.

7. Silent operation

The rotor rotates in an elastic stator, so it produces very little noise.

Knoll single screw pump working principle:

Single-screw pumps are manufactured and designed to transport liquids with different chemical properties and variable viscosity. These pumps can be customized to meet application requirements. These pumps operate with the help of precision mechanized single outer helical metal rotors and double inner helical elastomer stators. Fluid is transmitted through a cavity formed by rotation of the rotor in the stator.

The working principle of these pumps involves the rotation of a single helical rotor in the stator. Due to the positioning of the rotor and stator, a sealing line is formed along the axis of the rotor, which remains unchanged under both static and forced conditions. Through the rotation of the rotor, a plurality of cavities are formed along the suction and discharge ends of the pump. These cavities transfer fluid within the pump.
