Progressive cavity (PC) pumps are widely used in demanding applications—including pulp, paper, chemical industries, and mining and minerals processing—where they handle thick pastes, shear-sensitive fluids or abrasive slurries. One of the greatest risks to PC pumps is dry running—a condition where the pump operates without fluid, leading to excessive heat, stator damage and costly downtime.
Traditional dry run protection relies solely on temperature monitoring, but this method alone isn’t always enough. Some process media naturally lubricate the stator, delaying heat buildup and causing late detection. To address these challenges, Valmet's Flowrox PC pumps offer a multilayered approach, ensuring reliable protection in all conditions.
