Which operational risk escalates when a progressive cavity pump handles abrasive fluid at high shear rates?

💡 Explanation

When abrasive fluid encounters a progressive cavity pump experiencing high shear rates, accelerated abrasion occurs because smaller shear gaps increase the cutting action of particles on pump components. Therefore, exponential wear rates increase as the cutting action intensifies, rather than merely causing motor fluctuations, deformation, or seal failure which aren't directly related to the inherent mechanism.
