One of the most dynamic designs for driving the flow of variety of liquids,Progressive Cavity Pumps可以定制以有效处理具有不同粘度水平和化学性质的液体。渐进式腔泵包括精密机械式单个螺旋金属转子和双内部螺旋弹性体定子。当转子在定子内转动时，腔腔从吸入与流体一起排出。
这些泵用于妨碍处理压力并超越其他泵的情况下的情况，以便通过它们处理压力高达80巴的容量。使用吸力驾驶更高，更好的性能，这些PC泵是市场上可用的流行类别。这些PC泵也是粘性和磨蚀性液体的理想源。
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.
这些泵的工作原理涉及单个螺旋形转子在定子内的旋转。由于转子和定子的定位，沿转子的轴线沿着转子的轴线开发密封线，这在静态和诱导条件下坚持。通过转子的旋转，沿着抽吸和泵的排出端形成有几个空腔。这些空腔将流体转移到泵内。
Positive Displacement
由于单旋转元件，产生渐进腔，其提供均匀，计量和非脉动流动。发达的头部独立于转速，随着容量与速度成比例。
Self priming
固有的自吸泵，泵可以在鼾声上工作，不需要脚阀。
非堵塞
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.
内部速度低
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
转子turn inside a resilient stator and thus generate little noise.
Separate Bearing Housing
Fluids can be pumped without no contamination.
