Progressive Cavity

Also known as single-screw pumps and eccentric-screw pumps, these are perfect for a diverse list of applications involving various chemical processes, wastewater, adhesives, resins, pulpy liquids, oil, gasoline, and pharmaceutical products.  Progressive cavity pumps are especially useful for fluid displacement applications involving particularly thick, sludgy substances, as they allow space for small particles within the fluid to move through the pump without harming the mechanism or gumming up the shaft.  Our systems can handle particles of up to six inches in diameter, assuming the fluid they are in can keep them coated, and push through substances with a viscosity level ranging from 1-3,000,000 cps.

        History of Single-Screw Pumps

        Even though it was created in the middle years of the 20th century, the single-screw positive displacement pump has remained largely unchanged in design ever since.  The device was first conceived by a French entrepreneur, inventor, and industrialist named René Moineau.   Moineau was a pilot and a mechanic at the forefront of aeronautic innovation.  After spending most of his life working in fluid mechanics and aviation, by the 1930s Moineau saw the need for a self-priming, reversible pump that could offer consistent flow rates free from pulsation.  Today, almost a century after its creation, around and about a quarter million units of René Moineau’s invention are still sold annually--utilizing a design virtually identical to that of the original model.  

          How It Works

          Progressive cavity pumps are made up primarily of a long, cylindrical shaft which serves as the flow tube for whatever substance is being transferred.  Rather than being forced out via pressure or suction, the liquid is progressed (hence one of the many names for the device) through the discharge end of the tube by a rotating helioid shaft, using the divets in the corkscrew-like shape as a passageway.  The controlled flow area and continuous motion of the rotor allows fluids with a high viscosity to move through the pump as easily as thinner liquids.

          Benefits of a Single-Screw Pump

          Screw pumps offer a level of control not found in many other pump options.  Because the flow rate of the substance being transferred is directly correlated to the speed of the rotation of the internal screw, operators are able to adjust their work speed in whatever way the job at hand necessitates.  This makes them an ideal mechanism for moving large quantities of slurry and muck, when a liquid is shear sensitive, or when there are no good suction capabilities for the discharge end of the pump. Eccentric-screw pumps from Process & Power can achieve a flow rate of up to 2000 gallons per minute, while handling pressures up to 720 psi.
