What is a progressive cavity pump?
A progressive cavity pump is a positive displacement pump that moves fluid through sealed cavities formed between a rotating rotor and an elastomeric stator.
How does a progressive cavity pump work?
It works by progressing sealed cavities from suction to discharge as the rotor turns eccentrically inside the stator, producing continuous, low-pulsation flow.
What are the disadvantages of a progressive cavity pump?
Potential limitations include stator wear, sensitivity to dry running, speed-related wear, and elastomer compatibility constraints. These are application-dependent.
What fluids are best for progressive cavity pumps?
Progressive cavity pumps are commonly used for viscous, shear-sensitive, abrasive, or solids-laden fluids.
What is the difference between a gear pump and a progressive cavity pump?
Gear pumps use meshing gears and are typically applied to clean, lubricating fluids. Progressive cavity pumps use cavity progression and are better suited for viscous or solids-containing fluids.
