Progressive Cavity Pumps Provide Optimized Operation in Multiple Pulp & Paper Processes
Pumps & Systems, May 2014, by Nimish Sheth.
"Progressive cavity (PC) pumps are energy efficient and experience long life in harsh applications. Self-priming and with a low net positive suction head required, their positive displacement flow is proportionate to the speed and independent of discharge pressure. With their large capacity, PC pumps reach flow rates up to 1,500 gallons per minute and have high-pressure capability. With friction losses, pressures as high as 2,000 psi can be achieved. The addition of a cardan joint helps resolve wear and failure and delivers improved angularity and smooth transmission of radial and axial loads."
